Comments
I got a report today from Aspen Grove local, Scott Hart, of this slide in the far north end of Roberts Horn in Primrose Cirque. We can confirm that the slide was not there this morning at first light. It likely happened today around 12:30 and was triggered by the strong W winds. There were at least two other similar slides today in the Lost Creek path. Best guess currently is they were new windslabs failing at a density change.
