There's several places you can evaluate your progress. After the Abol Trail on top of Baxter if it doesn't look good you can just cut over to Hamlin and back across to the cut-off and down the Hunt Trail, a great loop hike there. Or you can go directly down the Hunt Trail and you would have hiked two great trails, I like the west side better than the east.
If it looks good you can cross the knife edge and make another evaluation on top of Chimney peak (going to Pamola peak is about 30 minutes round trip), you can always turn around there and you get to do KE in both directions and make it a better hike ( going down is the best way
).
If you continue and make it to Chimney Pond (water here, and probably no beavers up stream) then your choice would be to ascend Saddle trail to cut-off, if you're tired, or continue up to Hamlin and finish your planned trip. Going up the saddle is much easier than Hamlin Ridge. The cut-off trail contours the mountain at 4,600'.
All the people working at BSP are awesome people. I use to go to BSP headquarters in the middle of January, after the new year rush when I was the only one there. I spent many an hour perusing THE BIG BOOK with Mary Ellen or Gladys ( sometimes Buzz or Brenden would be there) planning my camping trips, really nice people. I've been up Baxter 3 times and Hamlin 4 times and I have never made the cut off times, but it would be a good idea to talk to the rangers. Peakbagger is right, definitely a case by case decision. Just because they let me go , doesn't mean the rangers will let you go.
I want to reiterate the rangers are really nice people. I've talked to at least a dozen of them and have always enjoyed a few laughs with them. I like BSP rules, I drive the speed limit and bring no electronics. I backpack to get away from all that crap, not to bring it with me. Don't forget - the rules are for the animals, not us. We are merely visitors.
When I said I would do that loop, that is the route I'm planning, I've never done it. A person has to be in top shape to accomplish it, and I'm not there- yet. Good luck, sounds like a classic loop.
