Diverse geology of the Hubbell Bench, Albuquerque Basin, New Mexico
— Vincent C. Kelley

The Hubbell bench lies along the western bases of the Manzanita, Manzano, and Los Pinos uplifts, central New Mexico. The bench is 310 km (2-6 mi) wide and about 88 km (55 mi) long, extending from the Tijeras fault on the north into the Joyita Hills, perhaps as far south as Socorro. The Hubbell bench is the largest of several benches which border the Albuquerque and Espanola basins (Kelley, 1977, 1978). Of these benches the Hubbell contains the largest variation of stratigraphy and structure. The geomorphic aspect of the bench has been produced by two factors: (1) pedimentation and surfacing of the Ortiz gravels of early Quaternary age; and (2) the Holocene-age, Hubbell Springs fault scarp, especially in the northern part of the bench.
