field observations from central Alaska. International Permafrost
Conference, 6th. Proceedings, p. 1346.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.https://nsidc.org/data/GGD247/versions/1GET DATAmailto:walters@uni.eduGet External DataCEOS IDN DIFVERSION 9.92003-07-252023-05-23NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCFull Dataset Citation2003. <i>Patterned Ground Features in Discontinuous Permafrost, Interior Alaska, USA.</i> [indicate subset used].
