Puget Lobe Chapter
Some Remarkable Apects of the Lake Missoula Floods
Location: Edmonds, WA
On Monday evening, Sept. 8, at 7 p.m., the chapter will be especially favored to have John Whitmer present a carefully developed report on "Some Remarkable Aspects of the Lake Missoula Floods". His presentation will be based on an analysis of the extent and effects of the major ice sheets at 25,000 years ago, 20,000 years ago (the last glacial maximum) and 15,000 years ago. He will give special attention to several topics that have been variously interpreted over the years, and still are, including the site of the hydraulic damming that impounded Lake Lewis, the remarkable landforms on the Waterville Plateau, and the effects of the Chelan Glacier on the landscape. It is also likely that he will refer to the new interest in the Canadian aspects of the full story of megafloods in the Columbia Basin. Time permitting, questions will be welcomed. His professional career was as a psychiatrist, but he has had a life-long fascination with geological exploration and analysis in the Pacific Northwest, and is a member of both the Northwest Geological Society and the Puget Lobe Chapter of IAFI, and has been president of NWGS. He is currently active as a popular teacher in the Telos extension program at Bellevue Community College, and as the leader of notable marine field trips in the San Juan Islands. He recently led a pre-conference field trip with the Tobacco Root Geological Society.----- The Chapter meets at the Edmonds Senior Center, right on the waterfront in Edmonds, at 220 Railroad Ave., between Main and Dayton Sts., a short distance south of the Kingston ferry dock and directly across the street from the AmTrak station. Meetings are always free and open to the public. Off-street parking is available, and there is elevator access to the second-floor meeting room. ----- Please note that the September Chapter meeting is usually on the second Monday of the month, rather than the first Monday (Labor Day). The next chapter meeting is scheduled for Nov. 3, program TBA.
