TYPE LOCATION: Caribou County, Idaho; 600 feet south and 1,200 feet east from the center of section 21, T. 7 S., R. 42 E.
RANGE IN CHARACTERISTICS: The mean annual soil temperature is 35 to 43 degrees F. The mean summer soil temperature is 45 to 55 degrees F. The mollic epipedon is 20 to 30 inches thick. The soils are frequently flooded for very long duration in April to June. An apparent high water table is at 1.0 to 2.0 feet from April to June. The A horizon has total calcium carbonate of 70 to 85 percent. The total clay is 40 to 65 percent of which 35 to 40 percent is carbonate clay.
The B and C horizons have total calcium carbonate of 85 to 100 percent.
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: Conda soils are on low stream terraces. Slopes are 0 to 4 percent. Elevation is 5,600 to 6,800 feet. The mean annual precipitation is 13 to 16 inches. The mean annual air temperature is 40 to 47 degrees F. The frost-free period is 50 to 80 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Lanark and Robin soils. Lanark and Robin soils are well drained and are on adjacent mountain slopes and fans.
DRAINAGE AND PERMEABILITY: Poorly drained, moderately slow permeability.
USE AND VEGETATION: Pasture and meadow hay. Native vegetation consists of redtop, tufted hairgrass, Nebraska sedge, lupine and silver sagebrush.
DISTRIBUTION AND EXTENT: Conda soils are inextensive. MLRA 13.

SERIES ESTABLISHED: Soda Springs-Bancroft Area, Idaho, 1925.
REMARKS: The description was drafter in 1969 but was not entered into the OSED file until 2003. The series was inactivated in 2003. Range of Characteristics were derived from the SCS-SOI-5 dated 8/90 (ID8825).
The series was previously classified as fine-loamy, mixed, calcareous. Based on laboratory data from Idaho, the soil ranges from 76 percent CaCO3 in the surface to 99 percent in the C horizon. After removal of the carbonate clay, the remaining clay values in the A horizon are 9, 7, and 8 percent respectively thus the change to coarse-loamy particle-size class and carbonatic mineralogy.
