From the Pacific Spring, the trail passes over an arid, undulating plain, in a west-by-north course, for about twenty-eight miles, when the "Little Sandy" River, a branch of the Green or Colorado River, presents itself, and furnishes the first water after leaving Pacific Spring. From the Little Sandy River, the trail passes over a plain of white sand or clay, and within twelve miles reaches the Big Sandy River, and passes along it for about eighteen miles, and then strikes off and crosses the Green River, or Colorado of the West. This river is shallow and only about seventy yards broad. The trail then continues down the Green River a short distance, and then, making a right angle, ascends the bluffs bordering the valley of the stream, in nearly a west course. The country then becomes still more broken and barren, and the trail ascends gradually to the summit of a ridge, from which it descends to the banks of the Black Fork, a tributary of the Green River. This Black Fork is crossed several times upon the route, but is not more than sixty yards wide and is very shallow. The trail leaves it to cut off the bends and then returns to it. The scenery along this part of the route is interesting, but the soil is frightfully sterile. Diverging from the stream the trail passes over a barren plain with no vegetation upon it except the wild sage, so common even in the most sterile country, and then passes through a bottom of grass, offering a good place for an encampment. Near this place is Fort Bridger, a small trading-post established by a Mr. Bridger. The buildings are two or three rudely constructed log cabins, and they are situated in a handsome fertile bottom, on the banks of a small stream. This fort is about eleven hundred miles from Independence, Missouri. From Fort Bridger, many parties anxious to explore the country, take the route by way of the south end of the great Salt Lake. But the scarcity of water and the other difficulties encountered in crossing the sterile plains and the great Salt Desert should be sufficient to deter emigrants with families from taking that direction. Oxen could not travel fast enough from one watering-place to another, and must necessarily perish from thirst. Besides, the route is but poorly defined, and may be wandered from very easily.
