Great Lakes Mesoscale convective complexs or MCCs can cause damage to wide swaths of forest and shatter glass in city buildings. These storms mainly occur during the night, and the systems sometimes have small embedded tornadoes, but more often straight-line winds accompanied by intense lightning. Historically, the Great Lakes, in addition to their lake ecology, were surrounded by various forest ecoregions (except in a relatively small area of southeast Lake Michigan where savanna or prairie occasionally intruded). Logging, urbanization, and agriculture uses have changed that relationship. In the early 21st century, Lake Superior's shores are 91% forested, Lake Huron 68%, Lake Ontario
Marine Museum of the Great Lakes Marine Museum of the Great Lakes The Marine Museum of the Great Lakes moved from the 1892 Kingston Dry Dock, a national historic site in Kingston, Ontario, Canada, when the federal government sold the property in 2016. The museum galleries are closed and the collections have been moved into storage until the museum finds a new property to reopen to the public. The Marine Museum office has moved to 53 Yonge Street, Kingston, Ontario. Once an important construction and repair facility for ships on the Great Lakes, the Kingston Dry Dock was constructed in 1890 by the Canadian federal government
