Angel Peak is a 6,988-foot spire composed of San Jose Formation and Nacimiento Formation sandstone that overlooks more than 10,000 acres of scenic badlands. Photo by Cynthia Connolly. San Juan Basin Tour, Research, and an Alamosaurus! Welcome to our 51st edition of Lite Geology!
Angel Peak National Recreation Area lies in the northern part of the San Juan Basin (Figure 5 and 6), a large structural depression that formed starting about 75 million years ago during compressional Laramide deformation (Cather, 2004).
Angels Peak stands on the eastern rim of a large area of badlands carved by a tributary of the San Juan River from Paleocene strata of the Nacimiento formation, and presumably also from Wasatchian strata of the San José (Simpson, 1948). This area of badlands lies some twelve miles south of Bloomfield, New Mexico in the Kutz Canyon drainage.
Robert W. Wilson's 'Preliminary Survey of a Paleocene Faunule from the Angels Peak Area, New Mexico' is a groundbreaking work that delves into the fossilized remains of an ancient fauna,...
Wind and water continue to sculpt the mudstone, siltstone and sandstone layers at Angel Peak, occasionally yielding new fossils. The fossilized remains of fish, lizards and crocodiles are embedded in the rock and petrified wood protrudes from the canyon walls.
Angel Peak, a 7000-foot pinnacle capped by sandstone, is a prominent landmark near Bloomfield in northwestern New Mexico. It is in the northern part of the San Juan Basin, a large structural depression that formed starting about 75 million years ago during compressional Laramide deformation.
14 Αυγ 2019 · Our study shows that the evolution of Paleocene fluvial systems in the San Juan Basin was complex and primarily responded to variations in subsidence-related sedimentary accommodation within the basin.
