Sunburst standard skin track to 3300′ in the later afternoon to see how the higher temps were affecting the snow and possibly observe natural glide, wet loose, wet slab activity.

Clear skies
Light winds - there was a cool breeze from Taylor that was not felt on Sunburst Ridge or higher on SW face.
Temps in the high 30F - 40Fs slightly inverted.
Various stages of crust starting to soften or not.
Anything with a westerly or northerly kick and slope angle was rock solid.
Southeasterly lower elevation snow was very punchy at 5:30
SW stayed supportable throughout tour
NW at 2900' had small 1-2 mm surface hoar and a thin crust that was becoming faceted and facets below.
HS @ 900': 100 cm
HS @ 1500' 100 cm
HS @ 2000' 210 cm
HS @ 2500' over 280 cm probe to 160 cm
HS @ 3000' over 280 cm probe to 190 cm
Quick pit dug on NW aspect at 2900'. HS: 90 cm shallow spot. Thin melt-freeze crust faceting with small facets below over a very stout melt-freeze crust (25 cm thick) over faceting melt freeze grains. This aspect had small surface hoar on the surface crust. Will be worth keeping track of next time we get snow.
Crust @ 900' was still supportable to boot pen @ 6 pm.
Sunburst glide cracks and surface conditions, roller balls are all old.
Sunburst glide cracks closer view
Witnessed glide avalanche on the south side of Tincan at 4:30 pm.
Tincan Proper and the Library, note the dates and the increase of melted out rocky areas, glide releases and dirty debris.
Thin faceting crust on NW @ 2900'.
Small surface hoar at 2900' NW aspect
