The Tahualtapa Project refers to “The Hill of the Ravens,” in Cahuilla lore, the mountain in the San Bernardino Valley that became known for the production of marble and later, more significantly, the production of cement. The works are combinations of photographs, sculpture, maps and plans for public art. The significance of what was later known as “Mt. Slover,” was that within its definition, its name illustrated how cosmology signified what the earth was used for and how it is regarded by different peoples.
