General Comments

I noticed a broad, somewhat blown-in crown in Castle Rock from a distance... Looked like a sizable natural from last weekend's storm.... Given the look of the crown and it's location, this upper elevation due north facing slope likely failed on faceted snow on the October/November interface....
