Show Notes
Back in the 1970s, a Canadian ice researcher developed a formula to determine how thick lake ice needed to be for logging trucks to drive across. It helps inform the Minnesota Department of Natural Resources' ice safety guidelines today. Reporter Kim Hyatt talks with host Erica Pearson about the history and science of ice roads.
