I'll start by saying I haven't been on the Knife Edge proper in winter, but I have been to many other parts of the park above and below treeline in all seasons.
That being said, your best bet for reservations is to call headquarters 207.723.5140 and ask about availability. As soon as you decide what is available and what dates you want, fill our your application form (available from
BSP) and mail it in ASAP.
Most of the popular long weekends are probably filled by now, but there will be plenty of space if you are flexible (the first day for winter reservations was Nov. 1).
One possible trip is:
Day 1: ski to Roaring Brook (11-12 miles)
Day 2: hike/ski up to Chimney Pond (3.3)
Day 3: hike up Dudley Tr. to Pamola (1.3), traverse KE and summit Baxter Peak (1.1). Head down Saddle to Chimney Pond (2.0)(or throw in Hamlin if all goes well).
Day 4: play and rest/ backup day for bad weather
Day 5: ski down to Roaring Brook and out to road (presumedly Abol).
The rangers use a three color rating system. A Red day will keep you from going anywhere above treeline. Any sign of bad weather will get a strong suggestion from the rangers that you stay off the KE and possibly any above treeline areas. The details of the rating system are availabe at the BSP site above.
A minimum of 4 people is required for above treeline trips. A stay at Roaring Brook the first night on the way in is required (unless you are on the coveted grandfathered lists of folks that are allowed to go to CP in one day).
Most people start at Abol Bridge on the Golden Rd., although I've heard of folks starting on the State Rd. as far as it is plowed (a few miles southeast of Togue Pond entrance). This latter option doesn't seem like a good idea to me.
