Narcisse Snake Dens
Narcisse, Canada
The Narcisse Snake Dens are a provincial wildlife management area located in the Rural Municipality of Armstrong about 6 km (3.7 mi) north of Narcisse, in the Canadian province of Manitoba. The dens are the winter home of tens of thousands of red-sided garter snakes (Thamnophis sirtalis parietalis).
These pits are known to house the largest concentration of this particular type of snake in the world. 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.
