We reached Ocoya, or Posé creek, on the 8th of August ; it was then almost dry, and water 
could be found only in deep and shaded holes of its channel. The low banks and bottom-land 
were timbered with a dense growth of cottonwoods and willows, and considerable grass was 
found along its borders. The green strip of vegetation showed out in strange contrast to the 
barren and parched surface of the surrounding hills, which were without trees or any green 
vegetation. 
This absence of trees permitted all the outlines to be seen, and they were all finely curved 
and rounded by the action of the weather. The soil upon their surfaces looks very light, and 
is nearly white. They appear to be composed of sand and sandy clay, regularly stratified, and 
alternating with strata of gravel and coarse sand. Pumice-stone, also, occurs in layers, and in 
some places forms a large part of the strata.
