I was up on the Illusion Peaks yesterday.
Pocket Glacier was actively calving, the debris hits the lip at he Buttress Toe, and some goes over the lip to the lowest bowl. Average frequency of about once an hour but some were as close together as 15 minutes.
You can see the very nasty upper serac on the Pocket Gl Marc-Andre talked about in his recent TR. Getting across this to get on the Bypass ramp looks sketch plus to me.
North Slesse Gl is calving from the bottom, which threatens the right side approach to the buttress toe. However we also saw one upper serac collapse which put a pile of blocks very close to where you get onto the North Rib.
Both were most active between about 9 AM and 4 PM.

Both glaciers, with zones of significant icefall during the day drawn in. Yikes!
