Recent dating of young zircons (which typically crystallize prior to eruption) place the date of the lava domes at 10,300 +/- 1000 years ago, consistent with early Holocene hydration rind dates from Obsidian Butte. Wave-cut benches originating from Lake Cahuilla, which existed from about 20,500 to 3000 years ago, prior to the 20th century formation of the Salton Sea due to an accidental spill-over of the Colorado River, are found on all of the domes. Older, sediment-buried Pleistocene rhyolitic lava domes have been found in geothermal drill holes. The Salton Sea geothermal field produces saline geothermal brines.
