    Tips

    March 6, 2026

    McGinnis Lake in Petroglyphs Provincial Park is one of the few meromictic lakes in southern Ontario, meaning its deeper water layers never mix with the surface. Because the bottom layer stays oxygen-free, the lake preserves undisturbed sediment layers that scientists use for studies. The lake’s stunning jade-green colour comes partly from calcium carbonate in the surrounding limestone, which often settles as marl along the shoreline.
