Snowpack Summary
Snow surface conditions are variable. Thin, breakable sun crusts have developed on steep solar aspects in the alpine. Melt freeze crusts exist at lower elevations on most aspects. At treeline and below treeline surface faceting and surface hoar growth (5mm) are forming; especially on shady aspects in sheltered locations. In the Duffy Lake and Coquihalla sits a well settled snowpack below the variable surface conditions. Additionally in the Coquilhalla hard wind slabs 5-15cm thick and have formed due to strong outflow winds. The older storm slab in the Coquihalla is about a meter deep and continues to settle and bond.
