Podzols in the Vicinity of the Nelchina and Tazlina Glaciers, Alaska1

Abstract

Abstract

Soils that resemble Podzols occur on well-drained valley slopes and ridges in areas adjoining the Nelchina and Tazlina Glaciers in interior Alaska. These soils had strikingly thin solum and were distinguished by marked textural differences that coincided with major horizon boundaries in many cases. Studies of six profiles from this area showed that the upper horizon, commonly the A2, is a silt loam and probably of loessial and volcanic ash origin, whereas the underlying gravelly sandy loam is of glacial drift origin. The surface silt appears to result from a lithologic discontinuity in the parent material and not from weathering. The presence of the discontinuity was reflected in textural differences and in base status of these soils, but the morphologic characteristics were those of Podzols. These soils appear related to the northern dwarf Podzols or nanopodzols (Kubiena).
