More detailed information about the avalanche: 

Drove out to Twin Lakes today to have a look around. Observed one significant avalanche that buried the Twin Lakes road for 900 ft just past the general store. SS-N-D2.5-R3-U. It ran 1500 ft and was over 1000 feet wide. It came close to hitting some of the cabins. The crown line was no longer visible. It occured during this week's storm. See photos. Also observed at least 3 other D2 slides in the area. Unfortunately we didn't have great light to look at the Crater Crest paths. The road is not plowed beyond the general store and we did not explore further down the road.  

We also traveled on SE-NE slopes in the buckeye road area today and found cold snow only on NE aspects. E and SE aspects got wet and were crusting over in the late afternoon. Only minimal rollerball activity observed. The snowpack has settled significantly over the last few days and travel has gotten considerably easier.
