Traveled up the Alpental Valley, to Source Lake, then up to Bryant Col. Few signs of instability until reaching the bench at ~5200ft on a NE aspect below Bryant Peak. Snow was cold and fluffy on the way up except SE aspects with sun exposure where we found a sun crust.
Upon reaching the 5200ft bench under Bryant Peak, we observed the possible start zone of the D2.5 avalanche mentioned in a 2/14 observation from Andy Harrington. The cause looked like a windslab that failed just below the cliff band below Bryant Peak on a NE aspect. The avalanche appeared to run full path and may have caused sympathetic releases while it traveled, but I did not ski down the debris field to confirm. The deepest part of the crown looked to be 3-4ft. Not sure if it falied on the 2/13 interface or a deeper layer in the snowpack (though I think 2/13 is the most probable bed surface) .
While skinning up to Bryant Col past the debris field, (5200-5450ft on NE aspect near ridgeline) the storm snow from 2/14 had windslab characteristics though it appeared to be healing. Small slabs adjcent to the slide path broke with some stomping.
