Apache Lake is another of the man-made lakes along the Salt
River (Rio Salado) in the Superstition Mountains of central Arizona. Also a popular
boating area, it is formed behind Horse Mesa Dam.
Rocks visible across the lake (the north side) include layers of volcanic ash. Behind them, rises Four Peaks
(although only three of the peaks stand out clearly from this angle). Four Peaks (as
it is called locally, singularly) is among the highest points in central Arizona, with an
elevation of 7657 feet, or 2334 meters. Here it forms the southern-most end of the
range known as the Mazatzal Mountains, and it actually become snow-covered at times during
the winter.
In an interesting inversion of usual geology, the peaks, which are composed
