Colorado has received so much snow this year that avalanche conditions are at historic levels.

Over the weekend, a couple of avalanches shut down I-70. Followed by more avalanches throughout the week, the main artery through Colorado was impassable.

Areas like Red Mountain Pass also closed roads due to dangerous conditions.

Now, the Colorado Avalanche Information Center is predicting the highest warning for avalanche dangers.

Backcountry avalanche conditions are extremely dangerous. Avoid travel in or below all avalanche terrain. Avalanches are running to valley floors and some are exceeding historic run outs. The avalanche danger is EXTREME (Level 5 of 5) for the Aspen, Gunnison, Sawatch, and Vail and Summit County zones. The avalanche danger is HIGH (Level 4 of 5) for the Steamboat and Flat Tops, Front Range, Grand Mesa, North San Juan, and South San Juan zones. These are exceptional avalanche conditions.

The Colorado Avalanche Information Center put together this map to show the areas with the highest dangers.
