Loreen Niewenhuis explored each of the five Great Lakes and their connecting waters. In words, photos, and video, she presented the geology of the largest system of fresh water lakes in the world and why there are tens of thousands of islands in the Great Lakes basin. She revealed how these islands are diverse in both geological underpinnings and in the life forms existing on the islands.

She also explained some of the scientific research on the islands that she assisted with during her island odyssey.

Niewenhuis speaks with the authority of an expert as she has a M.S. degree in the biological sciences. She raises important questions about preserving our wild places and protecting the fragile ecosystems on which we all depend. 

The event was sponsored by the University of Toledo. The lecture was held at the National Museum of the Great Lakes.
