Mount Diablo

Mount Diablo, also referenced as Mt. Diablo, is part of a small mountain range between Oakland and Stockton CA. Most of the area is surrounded by private land but Mount Diablo itself is protected from rock mining within Mount Diablo State Park. The mountain measures 3,849 feet (1,173 m) high and resembles a volcano because of its rapid rise surrounded by somewhat flat land. It marks the southern limit of the natural range for some plant species and the northern limit for others. This is one of the many reasons for protecting the ecological treasures that dwells on it.
