5203 |a"This volcano, informally named Kima'Kho, is one of more than 30 Pleistocene volcanoes on the Tuya-Kawdy plateau of northern British Columbia that record interactions with the Cordilleran ice sheet. This basaltic glaciovolcano features deposits resulting from explosive and effusive eruptions at 1.9 Ma and hosts multiple passage zones (transition surfaces between subaqueous and subaerial deposits (Russell et al., 2013)). Lithofacies include explosive lapilli tuff cone-forming deposits dominating the southern flanks of the edifice, which are partially overlain to the north by lava-fed deltas comprising lavas and tuff-breccia. Late-stage intrusions are identified by geological field relationships and 40Ar/39Ar geochronology. Explosive and effusive deposits show textural and stratigraphical indicators that delineate 'passage zones'. Six prominent passage zones record depth fluctuations of about 160 m in the englacial lake. Based on estimates of maximum lake depths, the reconstructed minimum ice thickness is about 40 m"--Abstract.
