I went up to Fairfield Hill to explore after the fire. The rock seems sketch. Does anyone know how fire affects rock and/or bolts? I assume for the worse, but I'd be curious to know some science behind things. I'd guess things vary dependent on heat and length of burn. Hmm. JaminT Rossetter

I've been checking it out quite a bit up there.

Not too many routes got toasted and they were ones that had trees near the base. Mainly caused a lot of spalding of the rock around the burned tree. You can see all the peeled rock flakes lying at the base and there are probably some less obvious loose flakes still on the wall. Hopefully they will peel off this winter.

The routes affected are: the 2 routes left of Blind, Physical Graffiti, possibly Yer Own Private Idaho, LL&L, Born X-Eyed (perhaps the worst effected), Alan Shepard Goes to Space, the 3 routes right of Shadowline, Only Pretty as You Feel, and a little on Hand on the Torch. The rest of the routes are still okay as far as I have done.

I went up there after the fire and bounce tested the first bolts on most of these routes. They held, but, I don't know. Especially the older Rawl three piece bolts (hex heads) may be compromised. I just don't know. I think the newer stainless steel bolts are probably okay but again, not totally sure. I may go up and replace the bolts on LL&L since it is somewhat popular and the bolts are pretty old Rawls.

Anyway, there were not that many routes badly effected by the burn, mainly the ones I mentioned. I'd stay off these until winter passes and hopefully the spalding will peel off this winter. I'd be real careful with it all.
