In 2007, Williams and Cole recommended that the Arroyo Ojito
Formation be abandoned, because the name was being used inconsistently and because the formation straddled a significant regional unconformity since named the Rincones paleosurface. They raised the Ceja Member, which lay above the Rincones
519:, Rio Puerco Member, and Santa Ana Mesa member. The Atrisco Member is reddish-brown mudstone and sandstone, some 85–100 meters (279–328 ft) thick, mostly found in the subsurface but distinctive on
