Formed miles deep within Earth's crust before being exhumed, this ancient structure has guided surface weathering and erosion for millions of years. Water lowers the melting points of rocks, so the sinking Farron plate caused the newly melted magma to migrate upward into the lithosphere. It was proposed, about 10 years ago, that the Tucson Mountain volcano and caldera formed over where the Santa Catalina Mountains now stand on the east side of Tucson. As the mountains were uplifted, it is likely that the Santa Margarita River was able to wear away the rock as fast as it was uplifted, staying in the same place at the same height as the rocks rose around it.
