Getting a Feel for Ice Sheet Hydrology + Channeled Scabland Geomorphology
Joel Gombiner, Washington Geological Survey Joel Gombiner, Washington Geological Survey, "Getting a feel for ice sheet hydrology + Channeled Scabland geomorphology" This presentation connects modern observations of ice sheet hydrology, the geomorphology of the Channeled Scabland, and recent publications on Washington’s Ice Age floods. The presentation consists of three parts: an explanation of a new lidar-based, semi-realistic oblique visualization and interpretive poster of Dry Falls (released 2025 by WGS); an intuitive overview of ice sheet hydrology with visits to Greenland, Iceland, and Antarctica; an update on recent Channeled Scabland science including evidence for subglacial tunnel channel floods from the Okanogan lobe and refined estimates of Missoula flood magnitudes. The in-person meeting will be held at Bellevue College T building Room 118 on Monday, March 2, 2026 at 7:00 PM. The live presentation will also be available on Zoom.
