By combining snowshoeing and an eye for art, visitors to Canadian National Parks have found a way to turn their wintry landscape into a giant canvas.
At La Maurice National Park in Quebec, weekend visitors are reserving untouched, frozen lakes to create massive snowshoe-imprinted works of art called snow tags.
Similar to crop circles, the displays are created by compacting the snow in perfect lines to form designs and images.
For those interested in participating, Parks Canada has created a series of drawings which can be recreated on a large scale by following GPS coordinates. Visitors are also welcome to create their own designs, although they require pre-approval.
The result can be viewed aerially from nearby lookouts.
