The Easiest way to do the Scar Ridge peaks I believe, is to do them each separately.
East peak from the East Pond Trail off the Kanc. We did an after work hike in early April (there was still snow), and the total trip time was 3 1/2 hrs. We found 2 canisters (this was back in 1994) amongst the fir wave - forest. Wasn't bad to manuver through, but I'm sure the snow cover was a big asset.
The Main peak from the top of Loon Mtn ski area. We did another after work hike, via the ski trails, total trip time was 3 3/4 hrs in late April. I remember a short, thick section of forest buffering the ski area.
Middle Scar, we ascended from Little East Pond. Very direct route. The forest was full of young evergreens, which made it a little tough to see your immediate surroundings. We actually walked into the Pond, for a more direct approach on the return trip, as we exchanged hoots with our Pond loving friend, Steve Smith. He had come out after work as well, to join us on the return walk of the Little East Pond trail. The Black Fly's were some of the worst I've experienced on that June afternoon. We had an extremely short summit / canister visit
Round trip was 3 1/4 hrs.
A more interesting route to the Main peak is via the Mack Brook F.S. road off the Tripoli road. Steve, Creston & I ascended the main south facing slide one Memorial Day weekend. There was a short THICK section above the slide, but then it opens up nicely. We traversed over to the north side of the ridge, descended a short distance, and hung out on the top of one of the slides (that was our destination).
In the Winter, I joined a East to West traverse, organized by The Great One, Master John H. Swanson
The snow makes such a differnce. We had a wonderful time, and barely noticed the thick sections we all remembered from our non-winter excursions.
I highly recommend doing a traverse, as it will be one trip you will not soon forget.
