Moonville soil and landscape
A representative soil profile of the Moonville soil series. This pedon of Moonville medial loam is generally in proximity to volcanic vents. The soils formed in volcanic ash and cinders. The darker areas in the Bk horizon are krotovinas, which are animal burrows that have been filled with soil material from the A and Bw horizons. (Soil Survey of Craters of the Moon National Monument and Preserve, Idaho; by Francis R. Kukachka, Natural Resources Conservation Service)
The Moonville series consists of very deep, well drained soils that formed in cinders, and ash. Moonville soils are on lava plains and south-facing mountain sideslopes and have slopes of 0 to 60 percent. The mean annual precipitation is about 18 inches and the mean annual air temperature is about 42 degrees F.
TAXONOMIC CLASS: Medial, amorphic, frigid Typic Vitrixerands
The soil moisture control section is dry for 90 to 120 consecutive days. The mean annual soil temperature is 42 to 47 degrees and the mean summer soil temperature is 59 to 66 degrees F. Depth to bedrock is over 60 inches. Depth to the calcic horizon is 20 to 35 inches. Phosphate retention is 50 to 80 percent. Acid-oxalate aluminum plus one-half the iron is 1.0 to 2.0. Glass percent is 5 to 30 percent. the 15-bar water on air dried samples is 12 to 15 percent and 20 to 30 percent on moist samples. Field estimated clay content is 12 to 26 percent. The soil profile contains 2 to 10 percent cinder gravels throughout.
USE AND VEGETATION: Used mainly for rangeland. Some areas are cultivated. Native vegetation is big sagebrush, three-tip sagebrush, antelope bitterbrush, Idaho fescue, bluebunch wheatgrass, Sandberg bluegrass, Thurber needlegrass, western yarrow, and prickly gilia.
DISTRIBUTION AND EXTENT: Southeastern Idaho; adjacent to Craters of the Moon National Monument. It is inextensive.
