Don’t miss this unique meromictic lake in the Petroglyphs Provincial Park. It’s blue/green colouring gives its secret away as a lake whose water layers don’t mix.

In most lakes, the surface and deep waters mix with one another at least once a year. In a meromictic lake, however, the surface deep waters do not intermix. These unusual lakes create unique colourations and extremely low-oxygen habitats.
