Selkirk Mountains

Generally, avalanche conditions are considered safe across all zones. Firm, stubborn wind-drifted snow above treeline are less likely to trigger but could still be reactive in isolated, wind-loaded areas. Cold, dry weather has led to firm, breakable crusts, which should be prioritized as the main travel hazard. The best conditions for travel are found near and below treeline.

Today is a great day to explore the mountains with stable snowpack, low avalanche hazard, and good visibility. Under the influence of dominant high pressure and mild weather, avalanche conditions have steadily improved, and the snowpack has continued to stabilize. However, pay attention to slope orientation: deeper snow drifting is more likely on north- and east-facing slopes, as well as cross-loaded terrain features above treeline. Areas beneath cornices or the backside of convex rolls are particularly prone to wind deposition. While these features are generally stubborn to fail, it’s still best to avoid them when possible.

If venturing into higher and more complex terrain, be mindful of snowpack interfaces with shallow trigger points. These areas, often located at the edges of wind drifts or near exposed rocks and trees, could make wind-drifted sections more prone to failure under the added weight of a skier or snowmobile. When selecting routes, make sure you have a good exit plan and avoid slopes that funnel into vegetated runouts or terrain traps. This proactive approach will help mitigate risks associated with potential avalanche releases in these isolated terrain features.

Yesterday, IPAC field staff observed a breakable sun crust on south- and east-facing slopes above treeline. With the long-term weather forecast in mind, a more robust sun crust may develop, which could pose concerns when significant snow falls on top of it. Currently, the crust isn’t an avalanche problem, but it can be tricky to travel on. Additionally, the sun crust, combined with firm, smooth wind-buffed snow above treeline, may create a fall and slide hazard. If you fall while skiing above treeline or descend a steep slope on a snowmobile, you may travel a long distance and have difficulty stopping.

Today also marks a shift in weather, as an Arctic air mass moves in from the north and east, bringing the coldest temperatures of the season so far. Given this, it’s important to build an extra safety margin into your plans to ensure you can safely return to your vehicle, as any accident or delay will become much more dangerous and difficult to manage.
