My buddy and I were planning a trip up the 11 o clock Couloir on Broken Top when he suggested we try skiing in and climbing North Sister instead. I wasn't sure what route he's thinking of, but it looks like Early Morning Couloir is an option. I know very little about this route. Does this route join up with the Bowling Alley? Are there other options from Pole Creek Trailhead for ascent or descent?
These are broad questions, but I'm not finding as much information as I had hoped from TRs and such in the winter.
