Two aggressive moose have led Beaver Creek to close the Royal Elk Glade, according to Vail Daily. A sign displayed near the Born Free Express chairlift warns skiers and snowboarders of the mother and calf that caused the closer.

Moose sightings have reportedly become more popular in the area in recent decades, with sightings at ski resorts and near highways increasing. 20 years ago, the Colorado Parks & Wildlife began a reintroduction effort in the state, as moose only occasionally wandered into Colorado from Wyoming up until the 1970s. These sightings confirm that the reintroduction effort was, without any doubt, a major success.

“Out of respect for local wildlife and to keep guests safe, Beaver Creek Ski Patrol has closed a portion of Royal Elk Glade due to a moose calf and its mother in the area. The terrain will reopen when it’s safe for wildlife and and guests.” Senior communications manager for Vail and Beaver Creek John Plack

Unfortunately, images and footage of the two culprits are currently unavailable, though if something pops up, there’s a good chance you’ll be able to find it here.
