MLRA 36 - New Mexico and Arizona Plateaus and Mesas

Arizona and New Mexico
69,130 km2 (26,690 mi2)

Soils:
Most of the soils are Argids and Orthents. They are well drained and fine textured to medium textured and have a mesic temperature regime, an aridic moisture regime, and mixed mineralogy. The nearly level to gently sloping Haplargids (Penistaja, Clovis, Fernando, Pankey, Silver, and Sedillo series) are on uplands, and the gently sloping to strongly sloping Haplargids are on piedmonts at the base of mountains. The gently sloping to strongly sloping Calciorthids (Harvey, Litle, and Las Lucas series) are on alluvial fans, and the gently sloping to rolling Calciorthids are on shale-controlled uplands. Shallow, gently sloping to moderately steep Torriorthents (Travessilla series) are on sandstone-controlled uplands. The deep, gently sloping to hilly Torriorthents (Pojoaque and Chilton series) are on dissected uplands, and the deep, strongly sloping to rolling Torriorthents are on alluvial fans. Shallow Argiustolls (Cabezon, Encierro, and Bernal series) are on uplands of basalt and sedimentary rocks. Haplustolls (Manzano and Prewitt series) and Torrifluvents (Lohmiller series) are on the stream deposits of valley floors and flood plains.
