The set of rounded dome-shaped mountains in the center of this view
is called South Mountain by Phoenicians (actually, its correct name is the
South Mountains, but no one here calls it that). The one on the left is
correctly named the Alta Ridge.
These ridges are the centerpieces of the largest city park in the world, with
40 miles (~65km) of trails. The highest point bears a forest of TV and radio
antennae.
Geologists come from far and wide to study them, as they are a classic and
easily visible example of a "" -- a geologic
structure probably indicating stretching of North America from southwest to northeast
during the middle . You can see this from
a different perspective in a view from space.
This picture is taken from Quartz Peak
(elevation 4052 feet, 1235m) -- you can look back from Alta Ridge to where this picture
was taken, for the reverse view. The valley in the
foreground is that of the Gila River, flowing from right (southeast) to left (northwest). Next View >>
