Geology of the Engle and Palomas Basins, Sierra County, New Mexico
Geologists and hydrologists have been interested in basin-fill sediments of the Engle and Palomas Basins in Sierra County since the early 1900s. These Rio Grande rift basins contain packages of sediment shed from the surrounding uplifts over the last ~27,000,000 years. Well logs indicate that these basin-fill deposits, named the Santa Fe Group, are as much as 2 kilometers thick in places.
