The Narcisse Snake Dens are home to five species of snakes. The red-sided garter snakes are the most numerous, and for one to three weeks in spring, they emerge from their winter dens to mate. Females are chased and caught by up to 100 males to form large mating balls, and later give birth to an average of 20 young. The mating gathering is thought to be the largest concentration of snakes in the world.
