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
