Slover Mountain (Mount Slover, Marble Mountain) is a former [2] mountain in Colton, in southwestern San Bernardino County and the Inland Empire region of Southern California. Now a hill, it was surface mined for limestone in the 20th century. [2] The Colton Joint Unified School District's continuation high school is named after the mountain. [3]
The mountain was known as Tahualtapa ("raven hill") by Native Americans and Cerrito Solo ("little solitary hill") by the colonial Spanish. [4]
The hill was named after a local 19th century hunter, Isaac Slover, who lived near it and who died in 1854 in the Cajon Pass from injuries caused by a bear. [5] The Colton Liberty Flag formerly stood atop the mountain. [4]
 Before the mountain was mined for marble and limestone,[ citation needed ] it stood as the tallest in the San Bernardino Valley, at 1,184 feet (361 m). [4]
