THE Summit Range of the
Rocky Mountains as they extend northward from the deep and narrow valley
of the Kicking Horse River has a special name—the Waputehk
Range,—derived, it is said, from a word which in the language of the
Stoney Indians means the White Goat.
From the summit of one
of the peaks in this range, the climber beholds a sea of mountains
running in long, nearly parallel, ridges, sometimes uniting and rising
to a higher altitude, and again dividing, so as to form countless spurs
and a complicated topography. In this range each ridge usually presents
a lofty escarpment and bare precipitous walls of rock on its eastern
face, while the opposite slope is more gentle. Here the Cambrian
sandstones and shales and the limestones of later ages may be seen in
clearly marked strata tilted up, generally, toward the east, though many
of the mountains reveal contortions and faults throughout their
structure, which indicate the wellnigh inconceivable forces that have
here been at work.
The Waputehk Mountains
have remained to this day but very little known, and almost totally
unexplored, in their interior portions. No passes are known through this
range between the Kicking Horse Pass on the south and the Howse Pass on
the north. Then another long interval northwards to the Athabasca Pass
is said by the Indians to offer an impassable barrier to men and horses.
The continuity of the range is well indicated by the fact that, for a
distance of one hundred miles, these mountains present only one pass
across the range available for horses. The several ridges which form
this range rise to a very uniform altitude of 10,000 or 11,000 feet. On
Palliser’s map of this region, one peak north of the Howse Pass, Mount
Forbes, is accredited with an altitude of 13,400 feet, and the standard
atlases have for many years placed the altitude of Mount Brown at 16,000
feet, and that of Mount Hooker at 15,700 feet, but there is much reason
to doubt that any mountains attain such heights in this part of the
Rocky Mountains.
A heavy snowfall, due
to the precipitation brought about by this lofty and continuous range,
as the westerly winds ascend and pass over it, and the existence of many
elevated plateaus, or large areas having gentle slopes, have conspired
to make vast neve regions and boundless snowfields among these
mountains. From the snowfields, long tongues of ice and large glaciers
descend into the valleys, and thus drain away the surplus material from
the
higher altitudes. No
other parts of the Rocky Mountains, south of Alaska, have glaciers and
snowfields which may compare in size or extent with those of the
Waputehk Range.
The desolate though
grand extent of gray cliffs and boundless snowfields, extending farther
than the eye can reach, when seen from a high altitude, gives no
suggestion of the delightful valleys below, where many beautiful lakes
nestle among the green forests, and form picturesque mirrors for the
surrounding rugged mountains. On the shores of one of these mountain
lakes, in the genial warmth of lower altitudes, where the water is
hemmed in, and encroached upon, by the trees and luxuriant vegetation
fostered by a moist climate, the explorer beholds each mountain peak as
the central point of interest in every view. Each cliff or massive
snow-covered mountain then appears an unscalable height reaching upward
toward the heavens,—a most inspiring work of nature, raising the eyes
and the thoughts above the common level of our earth. When seen from
high altitudes, a mountain appears merely as a part of a vast panorama
or a single element in a wild, limitless scene of desolate peaks, which
raise their bare, bleak summits among the sea of mountains far up into
the cold regions of the atmosphere, where they become white with eternal
snow, and bound by rigid glaciers.
Having become much
interested in reports of the vast dimensions of the glaciers in the
Waputehk Mountains, and the beauty of the lakes, especially near the
sources of the Bow River and the Little Fork of the Saskatchewan, I
started on August 14th, 1895, with the intention of visiting those
regions and spending some time there. My outfit
consisted of five
horses, a cook, and a packer. I had engaged Peyto for the latter
service, as he had been most efficient on our trip to Mount Assiniboine.
We left Laggan a
little before noon. Not
far from the station, there commenced an old tote-road, which runs
northward for many miles toward the source of the Bow River. This
tote-road had been hastily built for wagons, previous to the
construction of the railroad through the Kicking Horse Pass, for at one
time it was thought the line would cross the range by the Howse Pass.
Thus for several miles
we enjoyed easy and rapid travelling. The weather was mild and pleasant,
and my men seemed pleased at the prospect of another month or so in
camp.
In the course of a few
miles we came to the house of an old prospector. As this was the
farthest outpost of civilization, and the old man was reported to be an
interesting character, I entered the log-house for a brief visit. The
prospector’s name was Hunter. I found him at home and was cordially
welcomed. Here, in a state of solitude and absolute loneliness, with no
lake or stream to entertain, and surrounded by a bristling maze of
bleached bare sticks looking like the masts of countless ships in a
great harbor, this man had spent several years of his life, and,
moreover, was apparently happy. On his table I saw spread about
illustrated magazines from the United States and Canada, newspapers, and
books. The house was roughly but comfortably finished inside, and
furnished with good chairs and tables evidently imported from
civilization.
This isolated dwelling
and its solitary inhabitant reminded me somewhat of Thoreau at Walden
Pond. Like this lover of nature, Hunter enjoys his hermit life, which he
varies occasionally by a visit to the village of Laggan. Hunter had the
better house of the two men, but Thoreau must have had much more to
entertain him, in his garden, and the beautiful lake with its constant
change of light and shadow, and the surrounding forests full of
well-known plants and trees, where his bird and animal friends lived in
undisturbed possession.
No sooner had we taken
leave of this interesting home of the old prospector, than the trail
plunged into the intricacies of the burnt timber, and our horses were
severely tried. Peyto and another man had been at work on this part of
the trail for two days, very fortunately for us, as without some
clearing we should not have been able to force our way through.
The fire had run
through after the tote-road was built, so that the fallen timber now
rendered it nearly impassable in many places. The forest fires have been
much more frequent since the country has been opened by the whites, but
it would be a great mistake to conclude that before the arrival of
civilized men the country was clothed by an uninterrupted primeval
forest. When we read the accounts of Alexander Mackenzie, and the
earliest explorers in the Rocky Mountains, we find burnt timber
frequently mentioned.
However, these accounts
only cover the last one hundred years, and records of geology must be
sought previous to 1793. Dr. Dawson mentions a place near the Bow River
where forest trees at least one hundred years old are growing over a bed
of charcoal made by an ancient forest fire. Another bank near the Bow
River, not far from Banff, reveals seven layers of charcoal, and under
each layer the clay is reddened or otherwise changed by the heat. Thus
the oldest records carry us back thousands of years. The cause of these
ancient fires was probably, in great part, lightning, and possibly the
escaping camp fires of an aboriginal race of men.
Forest fires in the
Canadian Rockies only prevail at one season of the year—in July, August,
and September, —when the severe heat dries up the underbrush and fallen
timber. Earlier than this, everything is saturated by the melting snows
of winter, while in autumn the sharp frosts and heavy night dews keep
the forests damp. According to the condition of the trees, a forest fire
will burn sometimes slowly and sometimes with fearful rapidity. When a
long period of dry, hot weather has prevailed, the fire, once started,
leaps from tree to tree, while the sparks soar high into the air and,
dropping farther, kindle a thousand places at once. The furious uprush
of heated air causes a strong draught, which fans the fire into a still
more intense heat. Sometimes whirlwinds of smoke and heated air are seen
above the forest fires, and at other times the great mass of vapor and
smoke rises to such a height that condensation ensues, and clouds are
formed. In the summer of 1893, a forest fire was raging about five miles
east of Laggan. Standing at an altitude of 9000 feet, I had a grand view
of the ascending smoke and vapors, which rose in the form of a great
mushroom, or at other times more like a pine tree,—in fact, resembling a
volcanic eruption. Judging by the height of Mount Temple, the clouds
rose about 13,000 feet above the valley, or to an altitude of 18,000
feet above sea-level. It was a cumulus cloud, shining brilliant in the
sunlight, but often revealing a coppery cast from the presence of smoke.
The ascending vapors gave a striking example of one of the laws of
rising air currents. The tendency of an ascending column of air is to
break up into a succession of uprushes, separated by brief intervals of
repose, and not to rise steadily and constantly. The law was clearly
illustrated by this cloud, which, at intervals of about five or six
minutes, would nearly disappear and then rapidly form again and rise to
an immense height and magnitude.
In the course of a few
years after a forest fire has swept along its destructive course, the
work of regeneration begins, and a new crop of trees appears. Sometimes
the growth is alike all over the burnt region, young trees springing up
spontaneously everywhere, and sometimes the surrounding green forests
send out skirmishers, and gradually encroach on the burnt areas.
Curiously enough, however, a new kind of tree replaces the old almost
invariably. Out on the prairie the poplar usually follows the coniferous
trees, but in the Rockies, where the poplar can not grow at high
altitudes, the pines follow after spruce and balsam, or vice versa. The
contest of species in nature is so keen that the slightest advantage
gained by any, is sufficient to cause its universal establishment. This
is probably due to the fact that the soil becomes somewhat exhausted in
the particular elements needed by one species of tree, so that when they
are removed by an unnatural cause, new kinds have the advantage in the
renewed struggle for existence. Thus we have a natural rotation of crops
illustrated in the replacement of forest trees.
While we have been
considering the causes and effects of forest fires, our horses and men
have been struggling with the more material side of the question, and as
the imagination leaps lightly over all sorts of obstacles, let us now
overtake them as they arrive at a good camping place about eight miles
from Laggan. Here the Bow is no longer worthy the name of a river, but
is rather a broad, shallow stream, flowing with moderate rapidity.
Towards evening Peyto shot a black duck on the river, and I caught a
fine string of trout, so that our camp fare was much improved.
The next day we marched
for about three hours through light forests and extensive swamps,
finally pitching our camp near the first Bow Lake. The fishing was
remarkably fine in this part of the river. From a single pool I caught,
in less than three minutes, five trout which averaged more than one
pound each. We camped in this place for two days in order to have time
to explore about the lake. This first Bow Lake is about four miles long,
by perhaps one mile wide, and occupies the gently curving basin of a
valley which here sweeps into that of the Bow. There is something
remarkable in the unusual manner in which the Bow River divides itself
into two streams some time before it reaches this lake. The lesser of
these two ' streams continues in a straight course down the valley,
while the larger deviates to the west and flows into the lower end of
the lake, only to flow out again about a fourth of a mile farther down,
at the extreme end of the lake. The island thus formed is intersected
everywhere by the ancient courses of the river, which are now marked by
crooked and devious channels, in great part filled with clear water,
forming pools everywhere. This whole region must have once formed part
of a much larger lake, as for several miles down the valley there are
extensive swamps, almost perfectly level and underlaid by large deposits
of fine clay.
The drier places in
these muskegs are covered with a growth of bushes or clumps of trees,
gathered together on hummocks slightly elevated above the general level.
A rich growth of grass and sedge covers the lower and wetter places,
which often assume all the features of a peat bog, with a thick growth
of sphagnum mosses, while the ground trembles, for many yards about,
under the tread of men and horses.
The next day Peyto and
I crossed the river on one of our best horses known as the “Bay,” and
after turning him back towards the meadow, we started on a tramp around
the lake. We followed the west shore for the entire distance. The last
half mile was over a talus slope of loose stones, broken down from the
overhanging mountain, and now disposed at a very steep angle. There was
a barely perceptible shelf or beach about six inches wide, just at the
edge of the water, which we gladly took advantage of while it lasted.
The glacial stream
entering the lake has built out a curious delta, not fan-shaped as we
should expect, but almost perfectly straight from shore to shore. This
delta is a great gravel wash, nearly level, and quite bare of trees or
plants, except a few herbs, the seeds of which have lately been washed
down from higher up the valley. All this material has been carried into
the lake since the time when, in the great Ice Age, these valleys were
flooded with glaciers several thousand feet in depth.
As we turned the corner
near the end of the gravel wash, the glaciers at the head of the valley
began to
appear, and in a few
more steps we commanded a magnificent view of a great mountain,
literally covered by a vast sheet of ice and snow, from the very summit
down to our level. As we looked up the long gentle slope of this
mountain, we could hardly realize that it rose more than 5000 feet above
us. The glacier which descended into the valley was not very wide, but
showed the lines of flow very clearly. Six converging streams of ice
united to form the glacier on our right, while the glacier on the left
poured down a steep descent from the east, and formed a beautiful ice
cascade, where the sharp-pointed seracs, leaning forward, resembled a
cataract suddenly frozen and rendered motionless. As if by way of
contrast, a beautiful little waterfall poured gracefully over a dark
precipice of rock on the opposite side of the valley, and added motion
to this grand expanse of dazzling white snow. The loud-roaring, muddy
stream near where we stood, is one of the principal sources of the Bow,
and, after depositing its milky sediment in the lake, the waters flow
out purified and crystal clear, of that deep blue color characteristic
of glacial water. On a smaller scale this lake is like Lake Geneva, with
the Rhone entering at one end, muddy and polluted with glacial clays,
and flowing out at the other, transparently clear, and blue as the skies
above it.
After a partial ascent
of Mount Hector on the next day, we moved our camp and continued our
progress up the Bow River for about two hours. Here we camped on a
terrace near the water, surrounded on all sides by a very light forest
in a charming spot. On the following day the trail led us for two miles
through some very bad country, where the horses broke through the loose
ground between the roots of trees, and in their efforts to extricate
themselves were often in great danger of breaking a leg. Fortunately,
however, this was not of long duration. The trail soon improved and
became very clearly marked like a well made bridle-path. It led us along
the banks of the Bow, through groves of black pine, with a few spruces
intermingled. The ascent was constant, though gradual, and our altitude
was made apparent by the manner in which the trees grew in clumps, and
by the fact that the forests were no longer densely luxuriant, but quite
open, so that the horses could go easily among the trees in any
direction.
In about three hours
after leaving camp, our horses entered an open meadow where the trail
deserted us, but there was not the slightest difficulty in making good
progress. To the south, a great wall of rock rose to an immense height,
one of the lower escarpments of the Waputehk Range, and as we progressed
through the pleasant' moors a remarkable glacier was gradually revealed,
clinging to the cliffs in a three-pronged mass. As, one by one, these
branches of the glaciers were disclosed, they appeared first in profile,
and owing to the very steep pitch down which the ice was forced to
'descend, the glacier was rent and splintered into deep crevasses, with
sharp pinnacles of ice between, which appeared to lean out over the
steep descent and threaten to fall at any moment.
The absence of trees to
the north of us, and the general depression of the country in that
direction, gave us every indication that we were approaching the Upper
Bow Lake, nor were our surmises incorrect, for in a few minutes more of
progress, after seeing the glacier, glimpses of water surface were to be
had in the near distance among the trees. I went ahead of our column of
horses and selected a beautiful site for our camp, on the shore of the
lake, only a few yards from the water. The surrounding region was
certainly the most charming I have seen in the Rocky Mountains. The lake
on which we camped was nearly cut off from the main body of water to the
north, by a contraction of the shores to a narrow channel. In fact, it
might be regarded as a land-locked harbor of the Upper Bow Lake. Just
below our camping place the waters were contracted again, and descended
in a shallow rapid to another lake, resting against the mountain side on
the south. This latter lake is about three or four feet lower than the
others, and appeared to -be about two-thirds of a mile in length.
This region, for the
artist with pencil and brush, would be a fairy-land of inexhaustible
treasures. The shores along these various lakes were of a most irregular
nature, and in sweeping curves or sudden turns, formed innumerable coves
and bays, no less pleasing by reason of their small extent. Long, low
stretches of land, adorned with forest trees, stretched straight and
narrow far out into the two larger lakes, their ends dissolving into
chains of wooded islands, separated from the mainland by shallow
channels of the clearest water. In every direction were charming vistas
of wooded isles and bushy shores, while in the distance were the
irregular outlines of the mountains, their images often reflected in the
surface of the water. The very nature of the shores themselves, besides
their irregular contours, varied from place to place in a remarkable
manner. In one locality the waters became suddenly deep, the abrupt
shores were rocky, and formed low cliffs; in other places the bottom
shelved off more gradually, and there would be a narrow beach of sand
and small pebbles, ofttimes strewed with the wreckage of some storm,—a
massive tree trunk washed upon the beach, or stranded in shallow water
near the shore.
There were, moreover,
many shallow areas and swampy tracts where a rich, rank growth of water
grasses and sedges extended into the lake. Such border regions between
the land and water were perhaps the most beautiful and attractive of all
the many variations of these delightful shores. The coarse, saw-edged
leaves of the sedges, harsh to the touch, are pliant in the gentlest
breath of wind. The waving meadows of green banners, or ribbons, rising
above the water, uniform in height, and sensitive to the slightest air
motion, rustle continuously as the breezes sweep over them, and rub
their rough surfaces together.
From this region,
wherein were combined so many charming views of nature, with mountain
scenery, lakes, islands, and forests, all of the most attractive kind,
it proved impossible to move our camp for several days.
During the time that we
remained here, our explorations and wanderings took us along all the
shores and islands, and up the neighboring mountain slopes. On one of
the islands opposite our camp we discovered a small pool of singular
formation. The pool was nearly circular, and about ten yards in
diameter. The bottom was funnel-shaped, and in the very centre was a
black circle—in fact a bottomless hole—apparently connected by dark
subterranean channels with the depths of the adjacent lake. Its borders
were low and swampy, where the spongy ground quaked as we moved about,
and trembled so much that we feared at any moment to be swallowed up. In
fact the whole pool became rippled by the movements of its banks.
The glacier opposite
was the object of another trip, and this, too, proved interesting. The
neve on the flat plateau above discharges its surplus ice for the most
part by hanging glaciers, which from time to time break off and fall
down the precipice. We were often startled both day and night by the
thunder of these avalanches. Two tongues of ice, however, effect a
descent of the precipice where the slope is less steep, and though much
crevassed and splintered by the rapid motion, they reach the bottom
intact. Here the two streams, together with the accumulations of ice
constantly falling down from above, become welded into a single glacier,
which terminates only a short distance from the lake. The most unusual
circumstance about this glacier is the fact that the ice is much higher
at the very end than a little farther back, so that a great, swelling
mound of ice, about 200 feet thick, forms the termination.
About one fourth of a
mile below the end of the glacier, on an old moraine ridge now covered
over with luxuriant forest, we saw a towering cliff of rock rising above
the trees. This proved, on a closer examination, to be a separate
boulder, which must have been carried there by the ice a long time ago.
It was of colossal proportions, at least sixty feet high, and nearly as
large in its other dimensions. From the top we had an extensive view of
the lakes and valleys; while at its base we found on one side an
overhanging roof, making so complete a shelter, that it was not
difficult to imagine this place to-have been used by savages, in some
past age, as a cave dwelling.
Many years ago, not
less than one hundred, the forests on the slopes to the east of the
valley had been devastated by a fire. The long lapse of time intervening
had, however, nearly obliterated the dreary effects of this destruction.
The trees had replaced themselves scatteringly among the dead timber,
and attained a large size. The fallen trunks showed the great length of
time they had lain on the ground by the spongy, decomposed condition of
the wood. Many of the trunks had dissolved into red humus, the last
stage of slowly decomposing wood, and the fragments were disposed in
lines, bare of vegetation, indicating where each tree had found its
final resting-place.
The swampy shores and
large extent of water surface in this region fostered many varieties of
gnats, mosquitoes, and other insects, though, fortunately, not in such
great numbers as to be very troublesome. In fact, the season of the year
was approaching that period when the mosquitoes suddenly and regularly
disappear, for some unexplained reason. I have always noticed that in
the Canadian Rockies the mosquitoes become much reduced in numbers
between the 15th and 20th of August, and after that time cause little or
no trouble. In order, however, that there may be no lack of insect
pests, nature has substituted several species of small flies and
midgets, which appear about this time and follow in a rotation of
species, till the sharp frosts of October put an end to all active
insect life. Some of these small pests are no less troublesome than the
mosquitoes which have preceded them, though they afford a variation in
their manner of annoyance, and are accordingly the more endurable.
Along the reedy shores
of the lake and sometimes over its placid surface, when the air was
quiet toward evening, we often saw clouds of gnats hovering motionless
in one spot, or at times moving restlessly from place to place, like
some lightless will-o’-the-wisp, composed of a myriad of black points,
darting and circling one about another. Nature seems to love circular
motion: for just as the stars composing the cloudy nebulae revolve about
their centres of gravity in infinite numbers, moving forever, through an
infinity of space; so do these ephemeral creations of our world pass
their brief lives in a ceaseless vortex of complicated circles.
On one occasion we
built a raft to ferry us across the narrow part of the lake so that we
might try the fishing on the farther side. The raft was hastily
constructed, and, after we had reached deep water, it proved to be in a
state of stable equilibrium only when the upper surface was a yard under
water. After a thorough wetting we finally reached the shore, and
proceeded to build a more trustworthy craft.
On the 21st of August
we moved our camp down to the north end of the lake. Here the nature of
the scenery is entirely changed. Whereas the lower end of the lake
abounds in land-locked channels and wooded islands, so combined as to
make the most pleasing and artistic pictures from every shore, the other
part of this lake presents regular shore lines, and everything is formed
on a more extensive scale. The north side of the lake is curved in a
great arc, so symmetrical in appearance that it seems mathematically
perfect, and the eye sweeps along several miles of shore at a single
glance as though this were some bay on the sea-coast.
As we neared the north
end of the lake, a valley was disclosed toward the west, and an immense
glacier appeared descending from the crest of the Waputehk Range. Even
at a distance of three or four miles, this glacier revealed: its great
size. The lower part descended in several regular falls to nearly the
level of the lake. In the lower part, the glacier is less than a mile in
width, but above, the ice stream expands to three or four miles, and
extends back indefinitely, probably ten miles or more.
This Great Bow Glacier
had the same position relatively to the lake, as the glacier we visited
at the Lower Bow Lake held to that body of water.
A better knowledge of
these lakes revealed a striking similarity between them. Each lake
occupies a curving valley, which in each case enters the Bow valley from
the south. The two lakes are about the same size and nearly the same
shape, a long gentle curve about five times longer than broad. At the
head of each, though at slightly different distances, are large
glaciers. The glacial streams have likewise formed flat gravel washes,
or deltas, which have encroached regularly on the lake and formed a
straight line from shore to shore, perfectly similar one to another. A
further resemblance might be observed in the presence of two talus
slopes from the mountain sides, in each case on the south side of the
lake, near the delta. The Lower Bow Lake is about 5500 feet above
sea-level, while the upper lake is a little more than 6000 feet. The
increased altitude has the effect of making the forest more open, and
the country more generally accessible, in the region of the upper lake.
From one point on the shores of the upper lake, five large glaciers may
be counted, the least of which is two miles long, and the greatest has
an unknown extent, but is certainly ten miles in length.
Our camp was pleasantly
located in the woods not far from the water. After Peyto had put up the
tent and got the camp in order, with the horses enjoying a fine pasture,
he set off to explore the lake shore toward the Great Glacier. He
returned to camp about five o’clock carrying a fine lake trout which he
had caught. This fish
was taken near the
shore, and was probably a small one compared with those which live in
deeper water; nevertheless, it measured twenty - three inches in length,
and weighed about seven
CAMP AT UPPER BOW LAKE.
pounds. The Bow lakes
have a reputation for abounding in fish of a very large size. So far as
I am aware, no boat has ever sailed these waters, and there is no
certainty what size the fish may reach in the deeper parts of the lake.
Judging by trout which have been caught in Lake Minnewanka, near Banff,
it is very probable that they run as high as thirty or forty pounds.
The next day, Peyto and
I took a lunch with us and spent the entire day exploring and
photographing the glacier and its immediate neighborhood. The ice is not
hemmed in by any terminal moraine, but shelves down gradually to a thin
edge. In fact the termination of the glacier resembles somewhat the hoof
of a horse, or rather that of a rhinoceros, the divided portions being
formed by crevasses, while long thin projections of ice spread out
between. It is a very easy matter to get on the glacier, and quite safe
to proceed a long way on its smooth surface. We had some fine glimpses
of crevasses so deep that it was impossible to see the bottom, while the
rich blue color of the ice everywhere revealed to us marvels of colored
grottoes and hollow-sounding caverns, their sides dripping with the
surface waters. There is something peculiarly attractive, perhaps from
the danger, pertaining to a deep crevasse in a glacier. One stands near
the edge and throws, or pushes, large stones into these caverns, and
listens in awe to the hollow echoes from the depths, or the muffled
splash as the missile finally reaches a pool of water at the bottom.
There is a suggestion of a lingering death, should one make a false step
and fall down these horrible crevasses, where, wedged between icy walls
far below the surface, one could see the glimmering light of day above,
while starvation and cold prolong their agonies. A party of three
mountaineers thus lost their lives on Mount Blanc in 1820, and more than
forty years later their bodies were found at the foot of the Glacier des
Bossons, whither they had been slowly transported, a distance of several
miles, by the movement of the ice. The most dangerous crevasses are not
those of the so-called “dry glacier,” where the bare ice is everywhere
visible, but those of the neve regions where the crevasses are
concealed, or obscured by the overlying snow.
Not far from the foot
of the glacier the muddy stream flows through a miniature canyon, with
walls near together, cut out of a limestone formation. The water here
rushes some quarter of a mile, foaming and angry, as it dashes over many
a fall and cascade. Where the canyon is deepest an immense block of
limestone about twenty-five feet long has fallen down, and with either
end resting on the ' canyon walls, it affords a natural bridge over the
gloomy chasm. As probably no human being had ever crossed this bridge,
we felt a slight hesitation in making the attempt, fearing that even a
slight jar might be sufficient to dislodge the great mass. It proved,
however, quite safe and will undoubtedly remain where it is for many
years and afford a safe crossing-place for those who visit this
interesting region. |
