COMPETING SERIES: These are the Fulmer and Roliss series. Fulmer soils formed in alluvium and are poorly drained. Roliss soils formed in till and are in a 19 to 27 inch precipitation zone.
GEOGRAPHIC SETTING:
Landform: lake backswamps and low relief beaches
Elevation: 5,900 to 6,000 feet
Slope: 0 to 2 percent
Parent material: lacustrine sediments
Climate: long, cold winters; moist springs; warm, dry summers
Average annual precipitation: 13 to 16 inches
Average annual temperature: 41 to 45 degrees F.
Frost-free season: 70 to 90 days
GEOGRAPHICALLY ASSOCIATED SOILS: The North Beach series is sandy-skeletal over loamy with 40 to 85 percent rock fragments in the upper 20 to 30 inches of the soil profile and somewhat poorly drained.
DRAINAGE AND PERMEABILITY: Very poorly drained; negligible to low surface runoff; moderate permeability.
USE AND VEGETATION: These soils are used mainly for hayland or pasture. Native vegetation is mainly reeds, sedges, rushes, cattails, willow, and grasses.
DISTRIBUTION AND EXTENT: Sadducee soils are of small extent in southern Idaho along the west beach of Bear Lake.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana.
SERIES ESTABLISHED: Bear Lake County, Idaho, 2008. The name comes from nearby Sadducee Spring.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon - the zone from the soil surface to 10 inches (the A and Bg1 horizons ).
Aquic moisture regime and frigid temperature regime.
