First set aside as part of the Pinnacles Forest Reserve in 1906, Pinnacles has had several different federal management agencies, ranging from the U.S. Forest Service to the General Land Office and ultimately to the National Park Service. In 1908 President Theodore Roosevelt created Pinnacles National Monument with the power given him in the Antiquities Act of 1906. The initial area designated under the Antiquities Act was . The Forest Service relinquished control of the monument "circa" 1911, but no operating agency yet existed to receive it. No drivable roads existed into the park from communities like Hollister. Hollister boosters campaigned for federal funds for road-building. Congressman Everis A. Hayes made a trip into the Pinnacles in 1913 as part of the campaign for road funds. By 1914, primitive roads extended to Bear Valley.
