Congrats on getting off the hill or at least down to the snow cat. yea on the rescue timetable, if PMR is not patrolling, then its 90 mins to drive from town, 15 min cat load/unload, 45 min cat ride, 90mins to hogsback thats 4 hours minimum. It can be a long wait when the biggest exposure to the patient might be shock and hypothermia.
On your comment about the avalanche on the rim, the debris that you saw was caused by wind and a melt cycle and not a slide.
