The United States Congress designated the Hain Wilderness (map
) in 1976 and it now has a total of 15,985 acres
All of this wilderness is located in California
and is managed by the National Park Service.
Eons of wind and water, heat and frost produced the starkly angular crags and spires of today's Pinnacles National Park. Within the park lies the Hain Wilderness, previously called the Pinnacles Wilderness. The Hain Wilderness was renamed in January, 2013 in honor of Schuyler Hain, a homesteader who led tours to Bear Valley and through the caves, advocating the preservation of the region. Hain's efforts moved Theodore Roosevelt to establish Pinnacles National Monument in 1908, which formally became a national park in January, 2013.
About 23 million years ago, molten lava poured through the rift where the Pacific and North American tectonic plates collide, giving birth to a vast volcanic field. Then the Pacific Plate began creeping along the San Andreas Fault, carrying the Pinnacles to its current location 195 miles to the north. Along the way, forces of uplift and erosion shaped the rocks into the spectacular forms we see today.
Although Pinnacles was originally set aside to protect the unique rocks and caves, it is now also celebrated for its healthy native ecosystems. Vast expanses of chaparral, pocketed with woodlands and outcroppings of rocks and scree, support an impressive diversity of native plants and animals. More than 500 native flowering plant species share the landscape with 400 species of bees, beneath the gaze of soaring falcons and California condors.
