Quick Answer
Safest method for exiting a winter shelter is to wait for a period of calm weather, ideally after a storm has passed, to avoid high winds and drifting snow.
Assessing Conditions
Before exiting, assess the weather conditions. If there’s a high risk of avalanches or falling objects, wait until the danger has passed. A good rule of thumb is to wait at least 24 hours after a significant storm has ended. Monitor local weather forecasts and pay attention to signs like changing wind patterns or decreased snowfall.
Preparing for Exit
Once conditions are deemed safe, prepare for your exit by packing essential gear, including your shelter, sleeping bag, warm clothing, and a first-aid kit. Make sure to bring a map, compass, and a means of starting a fire. Also, consider packing a small daypack with snacks, water, and a warm hat, in case you get caught outside longer than expected.
Exit Techniques
When exiting your shelter, move slowly and carefully to avoid causing a collapse. If your shelter is buried or partially buried, use a probe or a ski pole to gauge the depth of the snow and identify potential weak points. If you must exit through a narrow opening, consider using a “jumar” or a " snow anchor" to secure the roof structure above you. Always move downhill first, and then proceed to your destination, taking regular breaks to rest and rehydrate.
