BLACK, YUMA COUNTY. 
On the first high point about 5 miles east of Parker and close to 
the eastern corner of the Colorado River Indian Reservation. There 
are several small rock cairns on this peak, but there is no danger of 
signal being confounded with them, as it is 10 feet high. It is good 
traveling from Parker straight to foot of mountain and good foot 
traveling from there to summit. 
Station mark: A bronze triangulation tablet cemented in a rock 
under center of a cairn 10 feet high.
