On October 10, 2014 President Obama designated some 350,000 acres of the Angeles National Forest in Southern California as the San Gabriel Mountains National Monument, the 13th national monument of his presidency. The monument designation follows a 14-year campaign by San Gabriel Mountains Forever, a coalition of environmental and community groups, including the Wilderness Society, the Sierra Club and Friends of the River. Under a national monument designation, the Forest Service would give priority to managing the safety of visitors, protecting natural resources and installing improvements, including new parking areas, restrooms, signs, educational kiosks and trails.
