I don't know how much time or effort dropping down the backside of Seward would save, though if there is a track that could be an option. Especially since our group is going for Emmons first. I would normally opt back the same way, but who knows. Maybe the register will tell us how their trip went, and if you guys head that way we may follow.
50 peaks, careful trying that drive in the Suburu if the clearance would be close. Hate to have you get stuck. (Hate it even more if it blocked the way!) We are taking a run at all three, so if you are so inclined for the trilogy attempt we can give you a ride in the back of the F-150 ... not saying that we won't get stuck, but the odds go down with the big truck. But, who knows, the road could have been packed down ... so just letting you know that option is there.
See you on the ridge!
ps. How far along is the cutover trail? Is it flagged, or obvious?
