Snowpit Observations
More detailed information about the snowpack: 

Went for a tour in the Williams Lake drainage. The snowpack at lower elevations was quickly melting out. A cold, clear night formed near surface facets on shadier North through East aspects near and above treeline. A widespread sun crust above treeline was quickly chewed up by todays strong sun. While the snow surface quickly warmed, we found only the uppermost 5 to 10cm's of the snowpack was beginning to moisten on East and South aspects. On this particular slope there were no signs of water percolating down into the snowpack.

We found a weak, decomposing snowpack in a shallow area above treeline on an Eastern aspect. This snowpit lacked a worrisome overlaying cohesive slab. Multiple facet-crust combos sat above decomposing slabs and a 1 to 2mm facet layer.

Northern wind sheltered slopes made for good skiing conditions as they maintained the cold recycled powder.

We did not observe any wet-loose avalanches today.

More detailed information about the weather: 

A cold, clear morning with a slight inversion quickly warmed due to the mid-morning sun. By noon higher elevations reached the upper 20's, with mid elevations climbing into the mid 30's. Below 10,000 feet temperatures climbed well into the mid 40's. Calm winds out of the East with gusts in the low teens. An overall beautiful, clear day with strong impacts from the sun.
