… was established on this date in 1908.
Rising out of the chaparral-covered Gabilan Mountains, east of central California’s Salinas Valley, are the spectacular remains of an ancient volcano. Massive monoliths, spires, sheer-walled canyons and talus passages define millions of years of erosion, faulting and tectonic plate movement. Within the monument’s boundaries lie 24,000 acres of diverse wildlands. The monument is renowned for the beauty and variety of its spring wildflowers. A rich diversity of wildlife can be observed throughout the year.
The rolling chaparral and dramatic rock faces of Pinnacles National Monument inspire loyalty in visitors, from picnickers to rock-climbers, and from stargazers to cave explorers. Pinnacles is visually stunning, as anyone who has seen the smooth orb of the moon glide from behind the crags of the High Peaks can attest, or who has watched the flashing black and white wings of acorn woodpeckers as they tuck acorns into the thick bark of gray pines. This striking beauty is attributable, in part, to the Monument’s geologic formations, showcase chaparral habitat, finely intergraded ecosystems, and protected native plant and animal diversity. Another special Pinnacles quality is its proximity to millions of people. . . .
Established in 1908 to preserve the incongruent and beautiful rock formations for which Pinnacles is named, the Monument originally protected only 2,060 acres. It now encompasses about 26,000 acres in the southern portion of the Gabilan Mountains, one of a series of parallel northwest-trending ridges and valleys that make up the Central Coast Range.
