COMPETING SERIES:
There are no competing series. The similar
Elyria soils effervesce with hydrochloric acid above 75 centimeters.
GEOGRAPHIC SETTING:

Landform: Fills and other leveled areas on stream terraces or plains mantled with eolian deposits
Slope: 0 to 5 percent

Climate: Cold, dry winters and hot summers with North American monsoon precipitation from July through August. The driest months are December through February.
GEOGRAPHICALLY ASSOCIATED SOILS:
These are the
Elyria,
Racas and
Southplatte soils:
Elyria soils have a coarse-loamy particle control section, form in sandy eolian or alluvial materials, and are found on fills on adjacent strath terraces.
Racas soils have a fine particle control section, form in loess, and are found on fills on adjacent loess-mantled plains.
Southplatte soils have cambic horizons and are found on fills on adjacent plains mantled with mixed eolian materials.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage class: Well drained
Saturated hydraulic conductivity: Moderately high (1.5 to 5 mm/sec)
Flooding: None to occasional with very brief duration
Ponding: None
USE AND VEGETATION:
Most areas are primarily used for urban development. Vegetation may include a mix of managed and unmanaged plant communities with a mix of native and non-native species. Many areas are vegetated with non-native ornamental landscaping and/or turfgrass associated with developed land uses. Some areas may exhibit weedy, invasive, and/or primary succession vegetation communities (e.g., abandoned lots and other unmanaged areas). The potential native vegetation is fourwing saltbush, winterfat, western wheatgrass, and blue grama.
DISTRIBUTION AND EXTENT:
Urban and other areas with human-modified landscapes on plains mantled by mixed eolian deposits and stream terraces, primarily on the east bank of the South Platte River in the vicinity of Denver in north-central Colorado. MLRA 67B - Central High Plains, Southern Part. These soils are of small extent.
