Abstract

Apparently, several pulses of salt flowed into the diapir between about 2-3 and 0.25Myr ago, and the diapir may still be active. The rising salt diapir impeded the flow of ancestral Fisher Creek, causing deposition of more than 125m of basin-fill sediments, and eventually diverted the creek down Cottonwood graben to the Dolores River about 0.25Myr ago. Onion Creek has eroded headward from the Colorado River, through both the diapir and the basin-fill sediments, and is about to capture Fisher Creek, restoring the original drainage course. -from Author
