Climbed to the top and made a sketch from a rounded half 
wooded hill that overlooks the great glat that opens between 
the falls and the river below Sulphur Hills . On the sketch 
the timber is indicated, the sage and grass, I can tell nothing 
about the extent of the Lake beds backward from the .river ex- 
cepting that opposite Crater Hill is a hill or series of slopes 
that are probably composed of itrem. As to the valley, I cannot 
say. The hills by the river are probably mostly of those beds. 
To my left as I look east there is a gulch that opens out 
to the river below the falls--say one mile. On the opposite 
side of it is a hill or ridge one side of which are springs. 
Also others at this head of the southern drainage.

September 5th. 
Visited Falls. Stopped above lower falls; made sketch 
and map. Followed down one mile. Made station on white 
point first about 3/4 of a mile below falls. Collected some 
very pretty specimens of the white brittle trachyte. There 
are many sulphur vents below and the walls are very bright 
with whites, light yellows etc. Half a mile farther on is 
Promontory Point- -a narrow white spur with a vertical face,, 
the most prominent point in this side of the river. The 
brilliant colors do not extend far beyond this. Say 1/2 or 
i/4 of a mile. Beyond that the steep 'walls are composed of 
a brownish gray trachyte which weathers (at least while wet) 
very dark. 
Turned back and crossed to Cascade Creek; found it
