Colorado is firmly in avalanche season and a skier near Beaver Creek triggered a big one on Wednesday, according to the Colorado Avalanche Information Center.

The post included images of the slope near Beaver Creek where the center said a skier caused an avalanche that triggered a second. A statewide map maintained by the agency ranks the risk of avalanches in many areas as “considerable,” the third-most severe category.

The CAIC warns of considerable avalanche risks in Colorado's mountains over the holiday weekend, following a recent skier-triggered slide.
