BABOQUIVARI PEAK. 105 
events far enough to examine the pass at the southern end of 
the valley before mentioned, which I shall in future call by a 
local Indian name—the Zazabe valley. 
A ride of twelve miles next morning (almost due west 
from Enviguetta) brought us in sight of the Baboquivari 
Peak. From some foot-hills on the east we looked westward 
across a valley (Zazabe valley), about twenty-five miles 
broad, and thrice that distance in length. Straight in front 
of us, on the opposite side, rose a range of bare rocky moun- 
tains of exquisite outline, and surmounted by that grand 
peak which formed so good a landmark for triangulation 
during the Mexican boundary survey—the Baboquivari Peak. 
_ The peak itself looks like one huge needle rock, thrust up 
_ vertically for a thousand feet above the highest mountain 
summit of the range. The valley seemed to be a wide, grass- 
- covered trough between two parallel mountain ranges, and 
in its centre there was a depression, the only indication of 
drainage visible on the surface. Bearing to the southward, 
we followed down the valley on the eastern slope until 
evening, having a range of mountains always near us on our 
left, when we made a dry camp and halted for the night. 
_ This day’s journey was about thirty miles. 
A five miles’ ride before breakfast next morning brought 
us to the end of the valley and to the commencement of the 
pass. Here the former had lessened in width 
: from twenty-five miles to a passage of scarcely 
] half a mile, which rose very gradually between the foot-hills 
' of the ranges on each side, and led across the divide out of 
’ ‘the Gila Basin. A short distance up @ side arroyo in that 
narrow part we found the Zazabe spring, where we watered 
our mules and breakfasted. After a ride of eleven miles 
further we struck a Papago trail leading from Fresnal and 
Dec. 5.
