Sunday, June the twentieth. Proceeding onwards, we came to the Indian Dance Rock, called so by Colonel Fremont in 1847. This rock is a huge pile of granite about half a mile in circumference and one hundred-fifty feet high. Its sides are decorated with numerous names of emigrants who passed them since '49. The road leads to the left of the rock along the river and crosses it about one and one-half miles from the said rock. Five miles onwards, passing over a very sandy road, we arrived at Devil's Gate, a precipice between the perpendicular walls of which the Sweetwater passed. This is undoubtedly the most interesting sight to the attentive traveler, made so by the profound deepness of the pass and the stratæ of ancient rocks laid open to the view of the naturalist. The rocks here are piled up in a strange chaos, consisting of primary (hypogene) rocks turned up on their edges in a nearly perpendicular position, intermixed with others in a horizontal and vertical position. The descent of this rock is, on account of its steepness, very difficult and connected with considerable danger. Too great precaution can't be taken by explorers. The river undergoes a fall of nearly ten or twelve feet, the water running very rapidly in its onward bound course. The road from here leads more or less along the river for twenty-five miles, where it separates in two, one crossing the river and the other takes over the bluffs. This latter road is extremely sandy and as heavy a pull for cattle as any part of the road we have passed. Teams that have not been taken proper care of, generally are lessened here by several of them breaking down by fatigue and feebleness. Traveling onwards we struck the river and passed along it for two miles where we ascended the bluffs again. Viewing the surrounding country, we discovered on the edges of the horizon a very large snow clad mountain, its summit nearly hid in the clouds, and its sides shining in a bedazzling luster. June the twenty-third. Rain setting in through the night, we were obliged to take a very early start. The alkali, with which the ground was covered, being dissolved by the water, might, if drunk by the cattle, have some very serious effect. Passing the bluffs, nothing of note happened, and after fourteen miles traveling, we arrived at the river banks, where we stopped to feed our cattle and took our own repast. Pasture being very gloomy here, we left for our afternoon's journey. After crossing the river we ascended a very steep hill, very stony and barren ground, the road leading down towards the river, where it turns at nearly a square angle, and ascends another very steep hill. The descent here is very rapid and slopes off into the Sweetwater Valley. Pursuing our course upwards, we met with some good pasture where we stopped and encamped for the night.
