Cyclical periods of global warming and cooling during the last 2.5 million years of Earth history led to multiple episodes of massive, advancing continental ice sheets in eastern North America.  In the Finger Lakes region, the most recent advance, a nearly two mile thick ice sheet formally known as the Wisconsin Stage, began 75,000 years ago and ended just 12,000 years ago.

By reading the modern topography, we can reasonably reconstruct the landscape appearance and historical story of glacial lakes that once stood in the Canandaigua Valley.  At this talk, Dr. Bruce Gilman (Professor Emeritus of Environmental Conservation at Finger Lakes Community College) will discuss the geologic history of two periglacial lakes – Glacial Lake Naples and Glacial Lake Middlesex – and the movement of retreating ice sheets that eventually gave way to our modern lake.

Dr. Bruce Gilman is Professor Emeritus of Environmental Conservation at Finger Lakes Community College.  In his retirement, he remains involved in many aspects of freshwater conservation, serving as a member of the Honeoye Lake Watershed Taskforce, consulting scientist for the Canandaigua Lake Watershed Council, gubernatorial appointee to the NYS Open Space Committee, steering committee member for the Finger Lakes Partnership for Regional Invasive Species Management, and scientific advisor to the Ontario County Water Resources Council.  He conducted his doctoral research, which he received from SUNY ESF, at the Conservancy’s Limerick Cedars Preserve.  Bruce is an avid birder, Adirondack 46’er, field botanist and author of the Ontario County Flora.  He enjoys time spent growing up again with his daughters and grandchildren.  Bruce lives with his wife Margo in Middlesex, near Canandaigua Lake, and has a cottage on Honeoye Lake.
