Winter Fat Biking is a refreshing alternative to traditional winter activities that many people can enjoy. Winter Fat biking is allowed on groomed motorized OSV trails and non-motorized winter trails at Obsidian Dome and Shady Rest. Only Purpose-built fat bikes with 3.8” wide tires or wider with a recommended tire pressure of 6-10 PSI are allowed on trails. If you leave a rut deeper than 2 inches or can’t ride in a straight line... it’s too soft to ride! Firm snow is the best snow. Conditions may deteriorate over the course of the day. Beware of icy patches. Get out and enjoy winter on two wheels!

Avalanche Forecast for 11/27/2024

AVALANCHE FORECAST: Over the past five days, two storms brought periods of heavy snowfall, strong winds, and dangerous avalanche conditions to the region. As the weather settles, avalanches breaking in new and wind-drifted snow will become less likely. Be prepared to assess the recent snow for signs of instability, like cracking underfoot, before venturing into avalanche terrain. We have very limited information about the snowpack at mid and upper elevations. If old snow has formed weak layers near the base of the snowpack, you can expect avalanche conditions to settle more slowly. Find out More
