More Natural Activity on Republic

03/07 - observed several crowns on Republic from Town Hill, likely from 03/06. Ray's had a slide on its west end which appeared to be isolated from the large avalanche that was filmed on the shoulder/Ray's. We saw up to 4 other crowns in Republic bowl on NE, N, and NW aspects including one that broke on the NE facing spines looker's left of the Fin that got legs and ran into the trees out of site (R1-D2?).

One note - while all of these slides, including the large one already reported on the shoulder were on northerly aspects, the majority of the trigger points appeared to be small, steep, thin, NE facing features. We surprisingly woke up to clear skies early on 03/06 and I wonder how much of an impact solar may have played. Other faces and features in the area that are strictly north facing or otherwise protected from the sun didn't appear to be sliding naturally.
