| 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-Uté 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 mésa, 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. |
| 29.50. | Cajou Creek.—The road leaves the river at the crossing, and runs toward a break in the San Bernadino Mountains; it ascends a sharp hill and enters a cedar thicket; it then ascends to the summit of the Cajou Pass; thence over a spur of the mountains into an arroyo or creek in a ravine; thence along the dry channel of the Cajou Creek for two miles, where the water begins to run, and from thence the road is rough to camp. |
| 7.00. | Cajou Creek.—Road continues along the creek to camp, and is rough. Wood, water, and grass at camp. |
| 20.00. | Cocomouga's Ranch.—On a pretty stream of running water. The road runs for six miles down the Cajou Creek, along its steep and rocky bed. It is here a good-sized stream. Captain Whipple's road here leaves the San Bernadino road, and turns to the west along the base of the mountains toward Los Angeles; it then crosses a prairie and strikes the ranch of Cocomouga. Wood, water, and grass. |
| 24.00. | Town of El Monté.—The road runs upon the northern border of a basin which is watered by many small streams, and is settled. The camp is on the pretty stream of San Gabriel, where there is a good camping-place. |
| 14.25. | City of Los Angeles.—The road passes the Mission of San Gabriel, then enters a ravine among hills and broken ground; it then descends and crosses the river which waters the valley, and enters the city. There is a good camp upon the point of a ridge on the left bank of the river. |
| 23.00. | San Pedro.—Good camp. |
