This is an aerial view of the Trout Lake Quarry in Innerkip, Ontario. Once a quarry mined for limestone, it filled with spring water and is now used as a recreational swimming hole and fishing spot. This is a popular site for cliff jumping and scuba diving. An underground water park was created with sunken ships, school buses, and planes.
