Domain:  Soil temperature and moisture data are representative of mixed forest communities on well drained upland locations. Soils are formed in loess and volcanic ash over drift deposits in the Cook Inlet Lowlands Major Land Resource Area ( illustrated in red).

US Soil Taxonomy:  medial over sandy or sandy-skeletal amorphic over mixed superactive, Andic Haplocryods.  Kashwitna Series.
Parent Material:
loess and volcanic ash over sandy and gravelly glacial outwash
General Soil Profile Description:
  Oi-0 to 6 cm; very dark brown; slightly decomposed plant material; pH 4.4
  E-6 to 10 cm; gray silt loam;  pH 4.6
  Bs1 and Bs2-10 to 37 cm; yellowish red and strong brown; silt loam and very fine sandy loam;  pH 5.4 to 5.6
  BC-37 to 51 cm; dark yellowish brown; silt loam; pH 5.7
  2C1 and 2C2-51 to 152 cm; very dark grayish brown; extremely cobbly loamy coarse sand; pH 5.7 to 5.8
Notable Features: 
Vocanic ash content of the silty eolian mantle ranges from 35 to 60 percent.  This is the major soil of the Point MacKenzie agricultural project.
