General Spring Avalanche Statement:

The Bridgeport Avalanche Center has closed its doors for the 2021-22 winter season.  We will no longer be issuing Snowpack Summaries for the Bridgeport Winter Recreation Area this season.  We will resume issuing Snowpack Summaries and observations in Late Fall 2022. 

Snowpack Discussion

Anything can happen during the spring months, from winter-like storms to warm and dry spring days.  It is best to not turn off those avalanche brains until the snow completely melts out and to keep spring hazards in mind while traveling in mountains this time of year.  You can keep updated with mountain weather forecasts throughout the spring at .  

During stretches of dry weather:

- Keep loose wet avalanches in mind during the spring months.  Travel early and end early to avoid wet snow instabilities during the heat of the day. 

- If you see recent avalanche activity or rollerballs & pinwheels, avoid similar aspects.

- Large avalanches are possible during extended stretches of warm weather with no overnight refreezes.  Increase your margin during these periods by avoiding complex terrain during the heat of the day.

During periods of winter-like weather:

- Keep wind slab and storm slab avalanche problems in mind while traveling in avalanche terrain. 

- If more than 6 inches of new snow accumulates, be sure to carefully assess the new snow for instabilities or consider avoiding avalanche terrain.

- The avalanche danger can rise quickly once the sun comes out, since it will heat the new snow and may cause wet snow avalanches.

- Limit your exposure in areas where avalanches can start and run.

Other Springtime Hazards:

- It’s been a below-average winter in the Sierra, so being mindful of shallow conditions below treeline this spring.  Shallowly buried rocks and downed trees are a couple of the possible hazards that you may come across on your sled or skis.  No one likes a core shot to their gear, or worse an injury to end the season with!

- Creeks and undermining snow.  This is a serious hazard that can have fatal consequences.  Be careful on snow bridges since they lose their structural integrity with the warming temperatures.  


If you get out into the field in the spring, let us know what you see and help your local backcountry community by submitting a public observation on our website.
