Las Cruces Country
William R. Seager, Russell E. Clemons and Jonathan F.Callender, eds., 1975, 376 pages.
Welcome to the twenty-sixth consecutive Fall Field Conference of the New Mexico Geological Society! The pervasive Silver Anniversary spirit of 1974 did not wane. The first day road log is from Las Cruces to southern San Andres Mountains and return. The tour route to the Ash Canyon-Love Ranch area of the southern San Andres Mountains first ascends the east slope of the Mesilla Valley to the floor of the Jornada del Muerto Basin. The tour route in and adjacent to the San Andres Mountains is on the White Sands Missile Range and National Wildlife Refuge reserves, and access is limited to parties with advance clearance and official escorts. The second day road log is from Las Cruces to the Sierra de las Uvas and Aden volcanic area. This tour emphasizes Cenozoic volcanic rocks and associated clastic units in basins west of the Mesilla Valley. The third day road log is from Las Cruces to North Mesilla Valley, Cedar Hills, San Diego Mountain, and Rincon area. This tour will emphasize middle to late Cenozoic stratigraphic units and structures along the Rio Grande Valley north of Las Cruces. Evidence of major Laramide uplift and early Tertiary erosion will be seen. The main route will be US-85 on the valley floor, with side trips into uplifts flanking Selden Canyon and Rincon Valley.
