Little Limestone Lake is considered to be one of the largest and most outstanding examples of a marl lake in the world. Located just north of Grand Rapids in the Manitoba Lowlands, Little Limestone derives its name from the unique karst (limestone) geology of the surrounding region. The colour of the lake changes visibly as calcite in the water reacts chemically to the heat of the sun.

Little Limestone recently became Manitoba’s 85th protected park reserve with the Mosakahiken Cree Nation taking an active stewardship role in its future as outlined in this memorandum of understanding.

At the end of June, Hilary and I went there to photograph the lake and help out the Manitoba Chapter of the Canada Parks & Wilderness Society (CPAWS). Below is day one. Many thanks to Bill Dubbert for touring us around and being such a hospitable guide.
