If you like gentle alpine walks in the sunshine with no wind then Jasper is the place for you! Just be mindful of the lurking persistent and deep persistent problems.
This weak layer, buried 20-40cm deep, is still reactive in snowpit tests and human triggering remains possible, particularly in shallow rocky start zones.
The base of the snowpack is inherently weak and untrustworthy. Human and natural triggering of these basal facets remains possible.
No recent avalanches have been observed
In sheltered areas 15 - 25cm of snow overlies the Feb 3rd crust, which ranges from 1-3cm thick in the alpine. On shaded aspects it exists up to 2500m and is breaking down due to the cold temperatures. On solar aspects it is up to 2800m. At lower elevations it is 15-20cm thick. The Persistent and Deep Persistent weak layers continue to produce whoomphing and sudden fractures in tests.
