Argixeroll and landscape
Soil profile: A representative soil profile of Typic Argixerolls. (Soil Survey of Pinnacles National Monument, California; by Ken Oster, Natural Resources Conservation Service)
Landscape: Typical landscape of Argixerolls on hills in the Central California Coast Range Major Land Resource Area at elevation of 980 to 2,490 feet. Overstory vegetation is Chamise and understory vegetation is Bushy spikemoss, black sage, wild oat, and California buckwheat.
Argixerolls are the Xerolls that have a relatively thin argillic horizon or one in which the percentage of clay decreases rapidly with increasing depth. Generally, the mollic epipedon is very dark brown and the argillic horizon is dark brown. Argixerolls formed mostly in mid-Pleistocene or earlier deposits or on surfaces of Tertiary age. Slopes range from nearly level to very steep. The natural vegetation is mostly grasses and shrubs, but some of the soils support coniferous forest vegetation with a grass and shrub understory and some have an open forest or savanna.
