A shot of the boardwalk around Crawford Lake, (visible through the trees) north of Toronto.
Crawford Lake is a meromictic lake: this means that it has layers of water that do not intermix. So, the water doesn’t circulate throughout the lake. In “normal” lakes, the water will mix during the seasons. In the case of Crawford Lake , only the upper lake gets mixed by the wind leaving the bottom layer settled. Due to the meromictic-nature of the lake, archaeologists have been able to drill core samples of pollen from hundreds of years ago and have used them to learn about the agricultural history of the Iroquois Indians that lived in the area.
As always, best seen on Black.
The blue flash on the tree, upper left, signifies that this trail is a side trail of the Bruce Trail. The Bruce Trail is a public footpath, running from Niagara to Tobermory along the Niagara Escarpment, a distance of 885 kms. (550 miles). It is maintained solely by volunteers.
