Sunday, 15th. Continued our journey over hills and ravines, going to almost every point of the compass in order to pass them. The day was very warm — the grass had been very good, but it was now very much parched up. Having come about 15 miles, we encamped on a small stream proceeding out of the mountains at no great distance from us. But we were surprised to see it become perfectly dry in the course of an hour; some of the guard said there was plenty of water in it about midnight.

I don’t know exactly where they were along the Bear River, but here is a nice picture of Logan Canyon in Cache Valley, Utah.
