1 or 1 1/4 miles away. Ho lake beds, only grayish trachyte 
with the usual white decomposed sanadin in irregular masses 
from l/2 and less '.0 3/3 inches. The dip is to the east at 
varying angles the strike toward the sulphur hills looking 
back. The surface of he meadow is covered with small frag- 
ments of obsidian with the white specks. The meadow is 3/4 
of a mile wide and extends up to the base of the mountains. 
The trail is in this valley. 
Recrossed (east to northeast) to the camp through the

The rock is a gray trachyte with very numerous sanadin, 
hard, laminated and apparently horizontal-- whether this is

promontory point two miles or more down, rising higher at

curves, while other parts of the cliff and expec ially that
