Bogard, who was an old hunter, and well acquainted with these creatures, shouldered his rifle, and said to me—“the game is up; and you now see the use of those big horns; when they fall by accident, or find it necessary to quit their foot-hold in the crevice, they fall upon their head at a great distance unharmed, even though it should be on the solid rock.”
Being on shore, and our canoe landed secure, we whiled away the greater part of this day amongst the wild and ragged cliffs, into which we had entered; and a part of our labours were vainly spent in the pursuit of a war-eagle. This noble bird is the one which the Indians in these regions, value so highly for their tail feathers, which are used as the most valued plumes for decorating the heads and dresses of their warriors. It is a beautiful bird, and, the Indians tell me, conquers all other varieties of eagles in the country; from which circumstance, the Indians respect the bird, and hold it in the highest esteem, and value its quills. I am unable so say to what variety it belongs; but I am sure it is not to be seen in any of our museums; nor is it to be found in America (I think), until one gets near to the base of the Rocky Mountains. This bird has often been called the calumet eagle and war-eagle; the last of which appellations I have already accounted for; and the other has arisen from the fact, that the Indians almost invariably ornament their calumets or pipes of peace with its quills.
Our day’s loitering brought us through many a wild scene; occasionally across the tracks of the grizzly bear, and, in sight merely of a band of buffaloes; “which got the wind of us,” and were out of the way, leaving us to return to our canoe at night, with a mere speck of good luck. Just before we reached the river, I heard the crack of a rifle, and in a few moments Bogard came in sight, and threw down from his shoulders a fine antelope; which added to our larder, and we were ready to proceed. We embarked and travelled until nightfall, when we encamped on a beautiful little prairie at the base of a series of grass-covered bluffs; and the next morning cooked our breakfast and ate it, and rowed on until late in the afternoon; when we stopped at the base of some huge clay bluffs, forming one of the most curious and romantic scenes imaginable. At this spot the river expands itself into the appearance somewhat of a beautiful lake; and in the midst of it, and on and about its sand-bars, floated and stood, hundreds and thousands of white swans and pelicans.
Though the scene in front of our encampment at this place was placid and beautiful; with its flowing water—its wild fowl—and its almost endless variety of gracefully sloping hills and green prairies in the distance; yet it was not less wild and picturesque in our rear, where the rugged and various coloured bluffs were grouped in all the wildest fancies and rudeness of Nature’s accidental varieties.
The whole country behind us seemed to have been dug and thrown up into huge piles, as if some giant mason had been there mixing his mortar and paints, and throwing together his rude models for some sublime structure of a colossal city;—with its walls—its domes—its ramparts—its huge porticos and galleries—its castles—its fosses and ditches;—and in the midst of his progress, he had abandoned his works to the destroying hand of time, which had already done much to tumble them down, and deface their noble structure; by jostling them together, with all their vivid colours, into an unsystematic and unintelligible mass of sublime ruins.
To this group of clay bluffs, which line the river for many miles in distance, the voyageurs have very appropriately given the name of “the Brick-kilns;” owing to their red appearance, which may be discovered in a clear day at the distance of many leagues.
By the action of water, or other power, the country seems to have been graded away; leaving occasionally a solitary mound or bluff, rising in a conical form to the height of two or three hundred feet, generally pointed or rounded at the top, and in some places grouped together in great numbers; some of which having a tabular surface on the top, and covered with a green turf. This fact (as all of those which are horizontal on their tops, and corresponding exactly with the summit level of the wide-spreading prairies in distance) clearly shows, that their present isolated and rounded forms have been produced by the action of waters: which have carried away the intervening earth, and left them in the picturesque shapes in which they are now seen.
A similar formation (or deformation) may be seen in hundreds of places on the shores of the Missouri river, and the actual progress of the operation by which it is produced; leaving yet for the singularity of this place, the peculiar feature, that nowhere else (to my knowledge) occurs; that the superstratum, forming the tops of these mounds (where they remain high enough to support anything of the original surface) is composed, for the depth of fifteen feet, of red pumice; terminating at its bottom, in a layer of several feet of sedimentary deposite, which is formed into endless conglomerates of basaltic crystals.
This strange feature in the country arrests the eye of a traveller suddenly, and as instantly brings him to the conclusion, that he stands in the midst of the ruins of an extinguished volcano.
As will be seen in the drawings ([plate 37], a near view, and [plate 38], a distant view), the sides of these conical bluffs (which are composed of strata of different coloured clays), are continually washing down by the effect of the rains and melting of the frost; and the superincumbent masses of pumice and basalt are crumbling off, and falling down to their bases; and from thence, in vast quantities, by the force of the gorges of water which are often cutting their channels between them—carried into the river, which is close by; and wafted for thousands of miles, floating as light as a cork upon its surface, and lodging in every pile of drift-wood from this place to the ocean.
