Let’s not page Sherlock Holmes to solve the intrigues that lurk within North America’s king-size inland freshwater lakes, which form the basis for the latest large-format travelogue to take residence at the Bristol IMAX Theater, located within Armory Square’s Museum of Science and Techonology (MOST), 500 S. Franklin St. Among the mysteries: why prehistoric creatures still exist in Lake Superior (pictured) and why do bull moose look so darned cute, at least to other bull moose.
