altogether quite irrigative in deposition. Toward the base 
the beds are maroon and the hard and soft layers follow each 
other in such a manner as to give cliffs a very regular 
series of horizontal lines. These lie upon the pale red bed 
massive sandstone generally regarded by Dr. H. as the beginning 
as 
of the Trias, but by others/carboniferous; this reaches to 
the river bed. 
August 7 - 
^ent with Chittenden to make a station on a little butte ^ 
South of the river and some S miles from camp. A la^rge 
area to the South West has been assigned to the pale red bed s. 
which in the country ridden over forms in many places a naked 
rock floor; the upper part of this bed is often gray and 
whitish. At the divide, at the head of the gulches passes. 
This bed rises into a low ridge (a.)
