ELT 150a

Elevation Range
Minimum: 
1269 m
Minimum in ft: 
4162 ft
Maximum: 
1698 m
Maximum in ft: 
5571 ft
Median: 
1416 m
Median in ft: 
4646 ft
Soil Summary: 
detailed soil survey information incomplete for this unit and is in conflict with the geology mapped for this area; this complex and variable dominantly metasedimentary unit is presently mapped within the granitic GES unit 475 and requires further investigation
Geologic Materials: 
slope alluvium, colluvium and residuum associated mostly with Bolsa Quartzite and Abrigo Formations (Cba); Apache Group and Troy Quartzite (Ya); and Escabrosa Limestone and Martin Formation (MDc); and Rice Peak porphyry and related rocks (TKr). They comprise 37%, 35%, and 26% of the unit, respectively
Landforms: 
moderately to finely dissected mountain slopes with moderate to deep drainage incision
