The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. Multi-season, multi-method geophysical data were collected both within the burned and unburned areas. Geophysical techniques used include Nuculear Magnetic Resonance (NMR) and Ground Penetrating Radar (GPR) data. NMR data were collected with a down borehole Dart tool (Vista Clara Inc.). GPR data were collected with a Sensors and Software pulseEKKO pro unit and 100 mHz antennas and a high power (1000V) transmitter. Soil temperature data were collected from the unburned black spruce forest at depths of 10, 30, 50 and 70 cm. NMR data were collected in June of 2018 and April of 2019, GPR data were collected in April of 2019, and soil temperature data were collected continuously from May 2017 through June of 2018.
