A provincial wildlife management area an hour north of Winnipeg. The dens are the winter home of tens of thousands of red-sided garter snakes. These pits are the largest known concentration in the world of this particular type of snake. Their winter dens are caverns formed by the area's water-worn limestone bedrock. The snakes can be viewed in April/May when they come up from their dens to the snake pits, where they mate, then they disperse into the nearby marshes for the summer. In September, you can watch them return to their dens.
