    Marmot Basin Ski area reports surface hoar extending into some alpine features. Solar crust on south aspects is also of concern. Dig and assess this layer before committing to terrain. Lots of whumpfing and shooting cracks have been observed on this layer across Jasper but no avalanches have been observed yet. Below tree line hazard specific to steep open terrain where this problem may be preserved.

Moderate

Avalanche Summary

No new avalanches have been observed or reported in the last 3 days.

Snowpack Summary

5-10cm of recent snow overlies previous wind slab in the alpine. At tree line and below a surface hoar layer can be found down 25-35cm in sheltered areas. The snowpack ranges from 40-100cm deep and can be unsupportive in locations.

Weather Summary

Monday will be a mix of sun and cloud with variable light winds and seasonal temperatures. Warming trend for Tuesday with light precipitation possible into Wednesday.

Terrain and Travel Advice
