Data Set ID:

Patterned Ground Features in Discontinuous Permafrost, Interior Alaska, USA, Version 1

This data set consists of active layer depth measurements, and photography and surveys of patterned ground activity at the Tangle Lakes, MacLaren Summit, and High Valley areas along the Denali Highway in Alaska. Repetitive photography and surveys of wooden dowels, metal spikes, and marked stones provided a rudimentary means of documenting and monitoring patterned ground activity. Active layer depth was measured annually with a permafrost probe, usually in late July and August.
