COMPETING SERIES: These are the Holsine, Malm, Matheson, McCaleb and Medicine Lodge series. Holsine soils have thick very fine sandy loam or silt loam layers below depths of 9 to 16 inches. Malm soils are 20 to 40 inches deep over basalt. Matheson soils have a B horizon. McCaleb soils have more than 40 percent carbonates in the control section. Medicine Lodge soils have more than 18 percent clay in the upper part of the particle-size control section.
GEOGRAPHIC SETTING: Lidy soils are on alluvial fans at elevations of 4,800 to 5,300 feet. Slopes are 0 to 4 percent. The soils formed in sandy alluvial deposits with a high percentage of limestone gravel. The semiarid climate has a frost-free period of 80 to 115 days and an average annual precipitation of 8 to 11 inches. Maximum precipitation falls in May and June.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bereniceton, Matheson, Montlid and Terreton soils. Bereniceton soils have more than 18 percent clay in the control section. Montlid soils are moderately well drained and have 18 to 35 percent clay in the particle-size control section. Terreton soils average 35 to 50 percent clay in the particle-size control section.
DRAINAGE AND PERMEABILITY: Well drained; very slow to slow runoff; moderately rapid permeability.
USE AND VEGETATION: Used for production of irrigated hay, small grains, potatoes and pasture and for rangeland. The natural vegetation is mainly big sagebrush, squirreltail, rabbitbrush and prickly pear.
DISTRIBUTION AND EXTENT: Southeastern Idaho. The series is of moderate extent.

REMARKS: This revision (5/95) changes the classification from Xerollic Calciorthids to Xeric Haplocalcids accoring to the 1994 edition of Keys to Soil Taxonomy. The Competing Series section of this OSD was not updated at this time.
