are of all detrees of coarseness and fineness. The masses 
of boulders and pebbles are all rounded or semi -rounded. 
Hot as river pebbles but rather as shore line pebbles. The 
bedding is exceedingly irregular. The coarse nixed with the 
fine on a regular jumble* yet with a traceable interbedding. 
Massive conglomerates with irregular layers of fine sandstone 
(same as in buttes north of --see specimens), and near the 
top of rather fine conglomerates which exhibits very max-iced 
cross bedding, ^itagether there are at least 300 feet of 
these mixed beds exposed. The finer beds are quite thin 
and appear to be almost clay states. They are white or 
light yellow and , generally contain more or less coarse 
pebbles. The largest masses seen were above 2 feet in 
length. These are probably less rounded than the smaller. 
The included pebbles are quite varied in composition* being 
mostly of volcanic origin . ( see fragments) but there are 
fragments of geyser ites * slates* etc. There are no granite 
rocks however*, and no paleozoic fragments. The two buttes 
seen to have the same series of beds. The t her these strata 
continue south into the plateau or not I cannot say. (,_t 
the falls there are breccias* yellow-trachytes with metallic 
looking streaks etc. pitchstone at top). They certainly 
extend west in a ridge that connects with the north buttte • 
There is a curious ridge extending east from the basin 
of the butte capped with huge masses of the conglomerates . 
There then are some upland parks in which there are buffalo
