COMPETING SERIES: These are the Cavehill, Fontreen, Granzan, Highup, Lizzant, Lonjon and Sylvaniam series. Cavehill, Highup, Lonjon and Sylvaniam soils are 20 to 40 inches to bedrock. Fontreen, Granzan and Lizzant soils have more than 18 percent clay in the particle-size control section.
GEOGRAPHIC SETTING: Lizdale soils are on fan terraces, mountainsides and hillsides at elevations of 4,800 to 7,000 feet. They formed in alluvium from calcareous sandstone, limestone and tuffaceous limestone. Slopes are 4 to 70 percent. The mean annual precipitation is 14 to 20 inches. The mean annual temperature is 40 to 45 degrees F. Frost free period is 65 to 100 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Burgie, Hondoho, Lonigan and Ridgecrest soils. These soils are on adjacent mountainsides. Burgi soils lack a calcic horizon. Hondoho soils have less than 40 percent calcium carbonate equivalent in the particle-size control section. Lonigan and Ridgecrest soils are moderately deep.
DRAINAGE AND PERMEABILITY: Well or somewhat excessively drained. Medium to very rapid runoff. Moderately rapid over rapid permeability.
USE AND VEGETATION: Lizdale soils are used mainly for livestock grazing. The potential native vegetation is mainly bluebunch wheatgrass and mountain big sagebrush.
DISTRIBUTION AND EXTENT: Southeastern Idaho. These soils are not extensive.
