Lo esencial

When the sun is out it packs a punch so watch for decreases in stability on steep solar aspects.  New surface hoar is growing overlying a crust along the divide.  Another soon to be new problem.

Weather Forecast

Freezing levels and temperatures are both forecast to drop over the next few days.  There isnt much of new snow in the 

Avalanche Summary

No new avalanche activity was observed today but there is evidence of a widespread cycle over this past week on all aspects at treeline and into the Alpine.  Heat was the suspected trigger in many cases.

Snowpack Summary

Wide wide wide widespread wind affect in Alpine terrain and into treeline areas.  A thin temperature crust can be found on the surface throughout the region on all aspects up to 2400m and on solar aspects up to 2900m.  At a profile on Thursday near Three Isle lake we found the 0116SH down 25cm and coming out CTM(11)(SP) and a more moderate RP result on the 1213CR down 50cm.  Windward slopes are as stripped as I've ever seen them personally and below treeline, the snowpack is a mixture of crusts and breakable facets.  Overall, not a pretty picture but thats just honest.
