Narcisse Snake Dens

Wildlife management area in Manitoba, Canada

The Narcisse Snake Dens is a provincial wildlife management area located in the Rural Municipality of Armstrong about 6 km (3.7 mi) north of Narcisse, Manitoba. 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. In the spring, they come up from their dens to the snake pits, where they mate, then they disperse into the nearby marshes for the summer.
