Mesa Prieta is a mesa in Sandoval County New Mexico. The mesa was formed by a basaltic lava flow approximately 3.3 myr. When the Rio Grande began to flow through the area, it eroded the softer sedimentary layers beneath the basaltic layer creating a mesa.[1] The sedimentary rocks include the Cretaceous Dakota Sandstone, Mancos Shale, and Gallup Sandstone.[2]
Rio Puerco flows south on the west side of the mesa. The Ojito Wilderness is to the east of the mesa, and Cabezon Peak is to the north.
