The groundwater hydraulics of seasonal frost mounds, North Fork Pass, Yukon Territory
Seasonal frost mounds occur in the North Fork Pass area in response to increased hydraulic potentials in perennial, spring-fed groundwater systems. Geochemical and isotope analyses indicate that local precipitation is the source of water for flow systems discharging from the springs. The direct meas...
