Standing above the ground at 3, 170 feet, Pinnacle Peak dominates the Sonoran Desert landscape. Largely composed of granite that was formed more than 1.4 billion years ago, the rock was exposed after years of erosion and uplifting. Minerals that have formed the granite are biotite mica, feldspar and quartz.

The resulting boulder, the Pinnacle Peak that we see today, is a result of the minerals being broken down by water, ice and gravity.

Located in the Sonoran Desert in Scottsdale, Arizona, Pinnacle Peak is home to a variety of plants and animals. Mountain lions, bobcats, coyotes, rattlesnakes have been able to adapt themselves to the desert climate. Despite the limited rainfall of only 7 inches per year, plants have been able to survive. Saguaro, Arizona's state flower, and cacti are able to absorb moisture and are able to live during the dry seasons.

Pinnacle Peak Park was established in 2003 to offer a wide range of activities for visitors. There is a 1.75-mile trail for hikers, horseback riding through the valley and rock climbing for experienced climbers.
