The Burn is the first route one comes to after hiking around the corner from the Southern End on one's way up the Stairmaster. Start on a block with a small tree.
P1: Climb up the face via cracks and through the overhang above to the Ecstasy Junior belay ledge. Most people stop here but there is a second pitch.
The Burns starts at a ~3 foot boulder about 100 ft up the stair master.
One can escape the crux fingercrack of the route by stepping left to a small corner system and a tree (The Burn Escape 5.7). I have never seen or head of anyone doing the second pitch, but it is in the guidebook. I think most people just climb the 2 pitch of EJ (5.4) which is one of the best easy pitches at Seneca.
The Burn can be top ropped from a set a shuts below the ledge (the ones at the ledge are for rapping). It is a bit of a rope stretch for a 60 m rope. You may have to stand on the boulder at the base to belay.
The shuts on the top of the Burn are no longer there as of 30 April 2007. Actually when I was there a couple weeks previous to this they had been cut. Similarly the anchors for sunshine are gone as well. If you rap on a single 60m from the rap rings / slung tree, you are going to have to down climb the ramp a bit. 5.easy downclimb though.
If you can't tell from the name of the climb, this route is very sustained and has a reputation as an ankle-buster. I watched my friend Andy Welter take a 20 footer and break his ankle on this climb in the late 90s.
