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. The upper part of this layer of pumice is of a brilliant red; and when the sun is shining upon it, is as bright and vivid as vermilion. It is porous and open, and its specific gravity but trifling. These curious bluffs must be seen as they are in nature; or else in a painting, where their colours are faithfully given, or they lose their picturesque beauty, which consists in the variety of their vivid tints. The strata of clay are alternating from red to yellow—white—brown and dark blue; and so curiously arranged, as to form the most pleasing and singular effects. During the day that I loitered about this strange scene, I left my men stretched upon the grass, by the canoe; and taking my rifle and sketch-book in my hand, I wandered and clambered through the rugged defiles between the bluffs; passing over and under the immense blocks of the pumice, that had fallen to their bases; determined, if possible, to find the crater, or source, from whence these strange phenomena had sprung; but after clambering and squeezing about for some time, I unfortunately came upon the enormous tracks of a grizzly bear, which, apparently, was travelling in the same direction (probably for a very different purpose) but a few moments before me; and my ardour for exploring was instantly so cooled down, that I hastily retraced my steps, and was satisfied with making my drawings, and collecting specimens of the lava and other minerals in its vicinity. After strolling about during the day, and contemplating the beauty of the scenes that were around me, while I sat upon the pinnacles of these pumice-capped mounds; most of which time, Bogard and Ba’tiste laid enjoying the pleasure of a “mountaineer’s nap”—we met together—took our coffee and dried buffalo tongues—spread our buffalo robes upon the grass, and enjoyed during the night the luxury of sleep, that belongs so peculiarly to the tired voyageur in these realms of pure air and dead silence.
