First Across the Continent [37]
interstice of the two on which it rests; but though the perpendicular interstice be destroyed, the horizontal one extends entirely through the whole work. The stones are proportioned to the thickness of the wall in which they are employed, being largest in the thickest walls. The thinner walls are composed of a single depth of the parallelopiped, while the thicker ones consist of two or more depths. These walls pass the river at several places, rising from the water's edge much above the sandstone bluffs, which they seem to penetrate; thence they cross in a straight line, on either side of the river, the plains, over which they tower to the height of from ten to seventy feet, until they lose themselves in the second range of hills. Sometimes they run parallel in several ranges near to each other, sometimes intersect each other at right angles, and have the appearance of walls of ancient houses or gardens."
The wall-like, canyon formations were charted by Lewis and Clark as "The Stone Walls." Their fantastic outlines have been admired and described by modern tourists, and some of them have been named "Cathedral Rocks," "Citadel Rock," "Hole in the Wall," and so on.
Passing out of this wonderful region, the expedition entered upon a more level country, here and there broken by bluffy formations which extended along the river, occasionally interspersed with low hills. Their journal says:
"In the plains near the river are the choke-cherry, yellow and red currant bushes, as well as the wild rose and prickly pear, both of which are now in bloom. From the tops of the river-hills, which are lower than usual, we enjoyed a delightful view of the rich, fertile plains on both sides, in many places extending from the river-cliffs to a great distance back. In these plains we meet, occasionally, large banks of pure sand, which were driven apparently by the southwest winds and there deposited. The plains are more fertile some distance from the river than near its banks, where the surface of the earth is very generally strewed with small pebbles, which appear to be smoothed and worn by the agitation of the waters with which they were, no doubt, once covered."
Under date of June 2d, the journal says:--
"The current of the river is strong but regular, the timber increases in quantity, the low grounds become more level and extensive, and the bluffs are lower than before. As the game is very abundant, we think it necessary to begin a collection of hides for the purpose of making a leathern boat, which we intend constructing shortly. The hunters, who were out the greater part of the day, brought in six elk, two buffalo, two mule-deer, and a bear. This last animal had nearly cost us the lives of two of our hunters, who were together when he attacked them. One of them narrowly escaped being caught, and the other, after running a considerable distance, concealed himself in some thick bushes, and, while the bear was in quick pursuit of his hiding-place, his companion came up, and fortunately shot the animal through the head."
Here the party came to the mouth of a large river which entered the Missouri from the northwest, at the site of the latter-day town of Ophir, Montana. This stream they named Maria's River, in honor of another Virginia damsel. So large and important in appearance was Maria's River that the explorers were not certain which was the main stream, that which came in from the north, or that which, flowing here in a general course from southwest to northeast, was really the true Missouri. The journal says:
"It now became an interesting question, which of these two streams is what the Minnetarees call Ahmateahza, or Missouri, which they describe as approaching very near to the Columbia. On our right decision much of the fate of the expedition depends; since if, after ascending to the Rocky Mountains or beyond them, we should find that the river we were following did not come near the Columbia, and be obliged to return, we should not only lose the travelling season, two months of which have already elapsed,
