timber. Small streams of icy water run down the slope on all 
sides. Ten acres of this parked upland transplanted into some 
Eastern estate would rival the finest product of the horti¬ 
culturist’s hand. A well beaten Indian trail crosses the 
divide just East of the peak. I was stir prised on approaching 
the summit from the Southeast to discover a bed or band of 
black shale extending across the East face and near the base 
of the pyramid, and that the trachyte mesa rested horizontally 
upon this, so: 
Beneath these shales and 
down almost to the timber 
there appeared to be another 
bed of trachyte, the debris 
made this somewhat obscure. 
The base of the summit mesa is escarped on the East. The v:all 
of trachyte rises from the shale contact vertically for some 
40 feet or more. The rock is fine grained and hard. The weather¬ 
ing is remarkable. The outside and exposed parts break up into 
small irregular fragments, while the interior is fctill quite 
massive. The relation of tills trachyte to the surrounding masses 
< 
does not appear. The upper part of the sharp peck Southeast i£

of the nearest large group of the San Miguel Mts. Cretaceous 
shales appear to underlie the trachyte in all cases and form
