A thick slab of more recent snow sits over several weak facet interfaces in the mid and lower snow pack where ever the snowpack is thin. Dig down to see if these facets are present and if so choose conservative terrain features.
Thin wind slabs are present in the alpine due to the fresh snow. There are also buried wind slabs that are becoming less reactive but should still be on your radar. Probe to find them, especially near ridge crests and in cross loaded areas.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Cool temperatures, flurries and a mix of sun and cloud are forecast. This should slowly moderate the snowpack.
Yoho has a much deeper snowpack than neighbouring areas. There is 250 cm at treeline and this has reduced the temperature gradient and helped facilitate rounding. The main weakness is at the Storm interface down 30-50 cm. The slab sits on large stellars and old rounding facets.
One older avalanche was noted today on a Southerly aspect in the Northern corner of Little Yoho. Neighbouring areas are reporting skier triggered avalanches.
