2002), sometimes referred to as the Norton Sound Highlands, are classified as Pergelic Cryaquepts to Pergelic Cryorthents (Rieger et al.
Although the soils sampled in the Seward Peninsula (mostly Pergelic Cryaquepts to Pergelic Cryorthents, Rieger et al.
The soils were originally classified as Sandy or Loamy Mixed Lithic or Pergelic
Haplocryods (Beyer et al.
Soils at the site are classified as Pergelic
Cryumbrepts and Pergelic
Cryochrepts (Osburne and Cline 1959, Burns 1980, Birkeland et al.
Soils of the subgroup Pergelic
Cryopsamments are associated with the open and stable dune communities.
Soils are Histic Pergelic
Cryaquepts with a 15-30 cm organic layer overlying mineral soil (Marion and Oechel 1993).

The accumulation of organic matter in the topsoil induces the formation of A-C soils: Lithic or Pergelic Cryorthents (Blume et al.
The Histosols are distinguished according to their decomposition degree and/or their mineral content: lithic, a solum [is less than] 40 cm; pergelic, a solum [is greater than] 40 cm and a mean annual soil temperature [is less than] 0 [degrees] C (Soil Survey Staff 1996).
Soils are in the Goldstream series and are classified as Histic Pergelic
Cryaquepts (Van Cleve et al.
This ridge-top area was above the zone of recent glaciation; the soils are Pergelic
Cryumbrepts, partially eolian in origin with moderately thick, fine-textured A horizons overlying a cambic B horizon (Burns 1980).
Horizon development is absent in the soils, which are classified as Pergelic
Cryochrepts by the USDA soil taxonomy system (Soil Survey Staff 1992).
