Mount Slover

Isaac "Cristobal" Slover (1780-1854) was killed by a bear on top of the mountain that later bore his name. For the next 140 years following, the elements to make concrete and cement were dug off this hill. Students and teachers at Colton High School, which is located not far from the site, often had to brace themselves often for the explosions which occurred when they were trying to blast rocks.

Slover was buried under a pepper tree at Agua Mansa Cemetery. The blasting operations ceased just prior to the end of the twentieth century.
