Written Report:
Two of us toured the trees on Todd Ridge today. The powder was excellent - among the best of the storm so far! During the day there was significant wind transport - enough to fill in much of our skin track on the ridge between our approach and exit, despite a lull in the precip today.

During our tour we stuck mostly to slopes less than 32 degrees. However, I unintentionally triggered a D1 storm slab by dropping over a small convex feature, which I estimated at about 35 degrees. This slide was in the north-facing trees at about 6700 feet, and the crown was about 12 inches. We were also able to intentionally trigger a small avalanche on an east-facing slope just below the ridge at 6800. In this case, the crown was a bit deeper - estimated at 18 inches.

Photos show the crown and debris from the latter avalanche, although the debris photo is a bit washed out. The third photo shows the wind-transport from today actively building a cornice.
