We remained in the vicinity of the river until about noon when we returned to camp, ate lunch, and spent the remainder of the day preparing specimens. The weather was very warm with a completely clear sky and little wind. I would estimate the high temperature in the early afternoon to have been about 90° F. In collecting we followed the wash down directly to the river and then followed the river upstream for about 2 mile, crossed it and explored a small pond on the opposite side of the valley and returned back to cross near the point where we originally reach the river. The river valley is about 500 yards wide and is lined by cliffs varying in height from 40 to over 100 feet high. The Cliffs of course are broken where the washes come in. The valley is very flat and the actual river bed is very little incised so that it occasionally spreads out to form marshy spots or splits into distributaries which return rejoin giving a braided pattern. At the few stretches where the river is between banks worthy of the name it is only about 6 feet wide. The gradient is low and the velocity of flow is also, a current barely being detectable in some stretches. The pond
