On Colorado River. 20.71. ....--The road, on leaving the Colorado, runs up over a gravelly ridge to a barren niesa, and descends the bed of the Mojave 4 or 5 miles above its mouth, and at 9-1/2 miles it passes springs near the point where the road turns around the western base of a mountain. There is no water at the camp, but grass in an arroya. 9.00. Pai-Ute Creek.--This is a fine stream, with good water and grass. 13.00. Arroyo.--Grass and wood; water is found by digging. 7.00. Fine Spring.--Good water and grass. The wagon-road passes around the hills, but an Indian trail leads through the ravine where the spring is. 19.00. Marl Spring.--This is a small but constant spring; excellent grass, and greasewood for fuel. 30.00. Lake.--The road follows a ridge for some distance, then descends to an arroyo, and in a few miles emerges into a sandy plain, where there is the dry bed of a lake, which is firm, and makes a smooth, good road. The camp is at some marshy pools of water. Good grass, and greasewood for fuel. 12.00. Mojave River.--Road passes through a valley of drifted sand, and at the camp strikes the river, which is here a beautiful stream of fresh water, 10 to 12 feet wide and a foot deep, with a hard, gravelly bottom. Grass in the hills near. 13.00. Mojave River.--The road ascends the river, the banks of which are covered with fine grass and mesquite wood. Good camps along here. 20.00. Mojave River.--The road leads up the river for a short distance, when it turns into an arroyo, and ascends to a low mesa, and continues along the border of a level prairie covered with fine bunch-grass. It then enters the river bottom again, which is here several miles wide, and well wooded. Grass good. 20.00. Mojave River.--Six miles from camp the road strikes the Mormon road, and crosses the stream near a Mormon camping-place. The trail runs along the river, which gets larger and has more timber on its banks as it is ascended. Good grass, wood, and water. 22.00. Mojave River.--A short distance from camp the valley contracts, but the road is good. It leaves the valley and crosses a gravelly ridge, but enters it again. Good grass, wood, and water. 15.00. Mojave River.--Road continues along the right bank of the river, in a southwest course, and crosses the river at camp. Good wood, water, and grass.
