Keya, Ownyate,
Prosper,
Renner,
Sampson, Traclee,
Vosburg and
Wetterdon series.
Bluewater are somewhat poorly drained.
Garrett soils have hue of 5YR or redder.
Haxtun soils have buried soil horizons within depth of 102 centimeters (40 inches).
Jarita soils have bedrock above depth of 102 centimeters (40 inches).
Farnum soils have a warm average annual soil temperature.
Funmar, Keya, Renner,
Tracylee and Wetterdon soils lack free carbonates above 30 inches.
Ownyate are formed in alluvium derived from granite, gneiss and schist.
Prosper soils have redoxomorphic features within 1 meter of the surface and are moderately well drained.
Renner soils also have iron and manganese concretions within 1 meter (39 inches) of the soil surface.
Sampson soils are influenced by arkosic sands.
Vosburg soils are mostly dry in the moisture control section from
May 15 to July 15.
Wetterdon soils have more than 15% but less than 35% fine sand and coarser in the control section and C horizon.
GEOGRAPHIC SETTING:
Landscape: stream valleys
Landform: alluvial fans, fan aprons, stream terraces, and drainageways
Elevations: 1097 to 1981 meters (3,600 to 6,500 feet)
