Our speaker will be Philip Long of the Lake Chelan Research Institute (LCRI). Phil will talk about “Exploration of Geomorphic Features in Lake Chelan with an Underwater Remotely Operated Vehicle (ROV)

Swath bathymetry, chirp sub-bottom reflection profiles, and sediment cores…. These were techniques recently used by the U.S. Geological Survey (June 2023) to collect data from Lake Chelan, WA,  The resulting information has provided insights into late- and post-glacial history of Lake Chelan. In addition, LCRI’s ROV dives have distinguished bedrock from till on lake bottom sediment profiles, and have directly observed landslide scarps, debris aprons, and other geomorphic features of interest to many of us here. Some of the features on the bottom of Lake Chelan resemble surface glacial features we are familiar with  on the Waterville Plateau! Moraines, kames, drumlins, kettles, underwater landslides….

Find out what’s going on at the bottom Lake Chelan!

The program is free and open to the public.
