Cheyenne Mountain Zoo Runs Important Wildland Fire Drill November 8, 2017 Although many people in the Pikes Peak region consider fire danger a thing of the past when the temperatures begin to drop, there is actually still a high risk for wildland fires during the fall and winter months. Because of this, Cheyenne Mountain Zoo plans to run a realistic, full-scale wildland fire safety drill on Thursday, November 9, 2017. The Zoo will close to guests at 2 p.m., with the last admission at 1 p.m.
