Quick report
Out to keep progress on this week's freeze-thaw cycle:
- Found no snow at lower elevations
- NW slopes at middle elevation were firm and supportable on ascent, ski pen was 6-8inches on descent
- Dogs started post-holing in isolated pockets above 6000'
- Above 6500', Northerly slopes still held ~ 1 foot of mostly dry snow above a complex of melt-freeze crusts
- Found a soft layer of wet rounding facets below the crust, this was unreactive in stability tests
- Steep and rocky terrain had produced loose dry and loose wet avalanches during the previous two days, but saw no action today.
- Increasing west winds and cloud cover might have helped quash wet loose
- Saw the slightest signs of previous wind loading and no blowing snow
We felt comfortable ascending and descending obvious avalanche paths.
No obvious signs of instability. Narry a roller ball today.
