HENRY MOUNTAINS 141 
camped on the side of the second peak of the range, at an elevation of 
about eight thousand feet above the sea. Our camp was on a small stream, 
evidently formed by the melting snows in the gulches above us. 
The Henry Mountains consist of five peaks, having a northerly and 
southerly axis, standing on the back of the plateau lying between the 
Dirty Devil and Colorado Rivers. They are completely isolated, being fifty 
miles from the Wasatch Plateau and Thousand Lake Mountain, on the west; 
about the same distance from the Sierra Abajo, on the east, and sixty miles 
from a huge, lone peak, which we have called the Navajo Mountain, on the 
south. The three northern peaks have an elevation of about eleven thou 
sand feet above the sea; the others, less. The crest of the most northern 
is a long, irregular ridge ; but the others rise to sharp points. 
From the summits of these mountains we could see the junction of the . 
canons of the Dirty Devil and Colorado Rivers. So, after such an examin 
ation of the range as our limited time would permit, we pursued a course a 
little north of east, and camped, the night after leaving the mountains, by a 
small stream, which, from the boulders in its bed, we called Trachyte Creek. 
The next day we followed its course, with considerable difficulty, until we 
found it would take us to the Colorado, at a point south of our point of 
destination. We then camped, and, after much search, found a way up and 
across the sand covered mesa lying north of the creek, and came to the head 
of a deep canon, that joined the Colorado two miles south of the mouth of 
the Dirty Devil River. I recognized it as one explored by members of our 
party when camped near its mouth last year, and felt confident that if we 
could once get down its precipitous side to the bottom, we could easily make 
our way to the river. After many efforts, we succeeded in descending, and 
camped that night near a spring in the canon. The next day we followed 
down its course without difficulty, and came to the river about two miles 
below the point where our boat was cached. 
Here we went into camp, and made our way on foot along the west 
bank of the Colorado to our boat, finding it undisturbed, although the high 
water had washed the sand from underneath her keel. The next day was 
spent in repairing the boat. With the aid of the materials brought from 
Kanab we were able to make her perfectly seaworthy.
