So Spring Slide Mountain isn't just a clever name

In the Southern Swan, we found a good overnight refreeze and good stability this afternoon.  Our biggest avalanche hazard was low likelihood, high consequence glide avalanches, which we managed by not lollygagging below glide cracks.

• 6" to 12" refreeze overnight remained well intact through the whole day, with supportive boot and ski pen on all but a few vegetated areas.
• Sun this morning gave way to thin, greenhousing clouds this afternoon which increased in thickness by this evening and started spitting snow.  The top inch of snow softened from solar, making for stable corn skiing. 
• We noted over a dozen glide cracks on sunny aspects at mid and upper elevations.  Several of these had released up to D3 avalanches in the past week.  We minimized our time spent below such slopes with a wary eye as we crossed beneath them. 
• Avalanche activity from last week's warmup was on sunny aspects at all elevations, and included:
  • Numerous D2 to D2.5 wet loose avalanches that snapped trees and crossed roads
  • Several wet slab avalanches up to D2.5.
  • Several glide avalanches up to D3.
