In isolated places where there was enough new snow for the strong wind to form into slabs, human triggering may be possible.
The snowpack is generally stable, it may be a good time to explore more complex terrain.

In isolated places where there was enough new snow for the strong wind to form into slabs, human triggering may be possible.
On Wednesday, west of Pincher Creek, several small solar-triggered wet loose avalanches were reported on steep sunny slopes.
Looking toward the weekend, we expect both natural and human-triggered avalanches to remain unlikely.
Reports have been limited in this area. If you venture into the backcountry, please consider submitting your observations to the MIN.
Around 5 cm of snow from overnight Thursday is covering a variety of surfaces. Previous strong to extreme winds scoured windward areas, and formed sastrugi and pockets of thin, hard wind slab on leeward slopes. On slopes facing the sun, these slabs may be covering a sun crust. In sheltered areas, you may find a few centimeters of soft snow covering facets or surface hoar.
The lower snowpack has no current layers of concern. Treeline snowpack depths range from 50 to 150 cm, depending on wind affect.
