Lineage:
The data set was obtained from the USGS National Map seamless server (http://seamless.usgs.gov). The map of soil mapping units was obtained from the Natural Resources Conservation Service (NRCS) Soil Data Mart (http://soildatamart.nrcs.usda.gov). The scripts used to predict soil mapping units and extract landforms are available via the authors website. The elevations range from 1400 to 1800 meters. There are six soil mapping units: (1) Holland family, 35 to 65% slopes; (2) Chaix-chawanakee family-rock outcrop complex; (3) Chaix family, deep, 5 to 25% slopes; (4) Chaix family, deep, 15 to 45% slopes, (5) Holland family, 5 to 65% slopes, valleys; (6) Chaix-chawanakee families-rock outcrop complex, hilltops.
