Soils map of the H J Andrews Exp Forest modified from 1964 soil survey. Joel Nordgen and Ted Dyrness collected additional field data in 1993 and 1994. Joel Nordgen revised the 1964 soils polygon based on these additional data. Ken Vance-Borland revised the original GIS soils layer based on Joel's interpretation, elevation contours, and the stream network. Polygon attributes were not changed.
