Pinnacles National Park

Pinnacles National Park

Pinnacles National Park in central California's Gabilan Mountains preserves 26,606 acres of dramatic volcanic landscape born from fire and sculpted by time. One of America's newest national parks, officially designated in 2013 after more than a century as a national monument, Pinnacles protects the eroded remnants of an ancient volcano that has traveled 195 miles from its original location through the slow but relentless movement of the San Andreas Fault. The park's towering rock spires, mysterious talus caves, and diverse ecosystems create a unique wilderness experience unlike any other in the National Park System.

The park's defining characteristic is its geological story of migration and transformation. Twenty-three million years ago, volcanic eruptions created the Pinnacles-Neenach Volcanic Field near present-day Lancaster, California. Over millennia, the Pacific Plate has carried the western half of this ancient volcano northward along the San Andreas Fault, separating it from its eastern counterpart (the Neenach Formation) and creating the dramatic landscape visitors see today. This ongoing tectonic journey, continuing at 1.5 inches per year, makes Pinnacles a living laboratory for understanding plate tectonics and geological processes.
