Great seconds In the Todd Lake area today. Mt partner and I skied northern aspects looking for untracked lines and were rewarded with supportable "powder snow" all around the area.
We observed an obviously weak interface between the new and old snow at 45cm. Upon digging deeper we observed a density change from fist to 4 finger snow on a northern aspect at 6800 feet in elevation that showed Weakness but no propagation with poor quality shear during our ECT. Full snowpack depth in the area was between 180cm and 150cm. We dug our pit to the firm crust at 120cm.
During the day we traveled through a small sun crust on the southern aspects that had thawed by the afternoon and many frozen tree bombs that had significantly affected the skiing in the trees for the worse. By the time we headed back to the car temperatures had risen to above freezing and the sun had significantly deteriorated the snow surface on eastern and southern aspects.
I suspect a firm melt-freeze crust will show up on sunny aspects tomorrow. We observed no other red flags and generally good overall stability.
Have fun tomorrow, leave late, and bring your helmet unless you want a TBI from treealanches.
