Outdoors
in
New Mexico's Gila Wilderness
near
Silver City, Pinos Altos, Las Cruces and
Lordsburg
To
thoroughly enjoy the wilderness experience, a
look at the topography is essential. The
Mogollon Mountains provide the main accent to
the landscape. This is the high point of the
drainage area for the Gila River system, which
drains the slopes of the Mogollon Rim. From the
headwaters, the creeks flow into the three forks
of the Gila, two of which, the Wast Fork and
Middle Fork, meet at the visitor center and join
the Eest Fork a few miles south of of the small
community of Gila Hot Springs. From here, the
Gila turns west and then south on its journey
into Arizona, south of the Mogollon
Range.
The
mountains and canyons of this region hve been
formed by a combination of forces, including
volcanic action, faulting and erosion.
Sixty-five million years ago, a great series of
volcanic eruptions shook the area. Later, more
than twenty million years ago, another period of
volcanism occurred. This activity created large
mesas which began to erode, creating today's
canyons. A later earthquake period brought
faulting. It is thought that the Mogollon Range
was created by this thrusting action. The
earlier volcanic eruptions are thought to have
brought the precious minerals, the gold and
silver for which Silver City is famous, close to
the surface. All of these geological changes
have turned what was an inland sea seventy
million years ago, into the heavily scored
landscape of today.
