In 1931, 500 students from San Diego State University (SDSU) painted a 400ft letter "S" on the side of the mountain, after which it took on its popular name. In April 1942, during World War II, the local military ordered the S covered up for the sake of national security. After the war the painting tradition was resurrected.In the 1970s, the annual repainting tradition was ceased for environmental and habitat protection, but suffered a brief resurgence in the late 1980s. The "S" has not been repainted for nearly three decades.Mission Trails Regional ParkThe entire mountain, with marked trails, is a protected area within Mission Trails Regional Park, which opened in 1972.TrailsThe main trail to the summit is a popular hiking destination taking hundreds of people per day to a 360-degree panorama of San Diego County.
