Summary

The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. Five ground penetrating radar (GPR) profiles were collected on 4/4/2019 at the West Fork of Dall Creek in interior Alaska. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. All collected profiles, other than the Central Midpoint Survey (CMP), transect the burn scar between start and end locations in unburned black spruce forest. Data were collected with a Sensors and Software pulseEKKO pro unit and 100 mHz antennas. Four of the lines were conducted as common offset surveys with manual data collection that employed a consistent antenna separation [...]
