More detailed information about the snowpack: 

Shallow Snowpack for the BWRA! Around 2.5" (6.4cm) new snow fell overnight on the 26th. Lowest density snow seen yet this season, light & fluffy. This snow will be easily effected by environmental factors including sun & wind. An average snowpack depth of 50cm (19.7") in the shade is still not enough to reopen for snowmobiling, please be patient. There is still poor layering structure to the snowpack. Facets & Depth Hoar Chains were observed in the thin snowpack with various Ice layers intermixed. Failures below the uppermost facet/ice crust sangwich were seen with moderate to hard forces, 15 cm deep.
