Steep southerlies were very warm + wet. Many rollerballs were seen on PMS bowl originating from the large cornice. Recent wet loose activity. Around 2:30pm, we got some rollerballs going down a steep southerly and they moved as unit (~2ft x ~4ft), but broke apart after sliding for about 5 feet (I had thought we were going to start a wet loose). This was adjacent to a recent wet loose path running ~1000ft starting around 3500'
