From South Coast Touring:
Conny Amelunxen Oct 30, 2021

 Right on sounds like you found the right place! (referring to Shovel Nose Creek) I flew over the Ipsoot zone and poked around in the Pebble Creek area. Same snowpack depths but there was a softer layer buried under the more dense surface 20-30 cm. This layer has (and continued) to be super active. There were several avalanches on north asp that occurred at the tail end of the last storm. These propagated on average 30-50 m but some up to 200 m. Through the day mainly southerly and SW were sliding with the extreme snow transport and sun. There were 2 slides we might call size 3 but most were in the sz 1.5-2.5 range. We figured high end of CONSIDERABLE.
