The story of the change from a vast forest of huge white pines to the very different landscape we see today is also a story of the people who made the change – the lumberjacks. Dave Crawford will use photos, mostly taken 100 to 150 years ago, to tell the story, with a focus on the St. Croix River watershed, the heart of white pine logging in the Midwest. Bio: Dave Crawford is a retired Minnesota State Park Naturalist. He worked at Interstate and Wild River State Parks in the St. Croix Valley for 34 years. He continues to volunteer for citizen science projects and naturalist mentoring, and does occasional talks and hikes for environmental education organizations.

Tony Manzara will describe the 10-year history of experiments which demonstrate a process known as Albedo Modification, which slows down the melting of ice which is exposed to sunlight. Work was done on ponds in Minnesota and Alaska, simulated glaciers, and a snowfield in Iceland. Bio: Dr. Anthony Manzara is a retired chemist with 3M. He is also the co-founder of the Sally Manzara Nature Center, in honor of his late wife. Tony still works on experiments that interest him and volunteers his time at the nature center, all while encouraging people of all ages to embrace their passion in the areas of science and nature.
