While I certainly can't speak for the rest of the people around here, but FWIW that would be the only area nearby I would consider posting. You could always ask the boys at C.O.R. (the local access stewards) if they are cool with it.
It was published in the 'Climbing Oregon' guidebook already... so it is probably fair game. But I personally don't plan on posting any of the other areas around there.
Hey Phil! I am not trying to get you to conform, and you know as well as anyone that you can do whatever you want. Of all the bouldering areas in Central Oregon, Sisters is one of the more well known... so posting info on it doesn't seem like a big deal to me.
It seems like from what I have observed from other climbers in the area, posting directions to most of the other zones isn't advised. Just the vibe I've felt. That being said... I have NEVER met anyone out bouldering here that wasn't stoked to see some other folks and climb together.
Central Oregon Rocks, INC. is a local non-profit dedicated to preserving local access to bouldering areas and they would be the best people to approach with this question. Phone Number: (541) 390-1995 Email: firstname.lastname@example.org
As a local climber I would rather not see any bouldering areas be posted online as I'm selfish. I don't want any traveling climber from who knows where inundating our local boulders on the weekend. Tick marking, littering, etc. I really enjoy the word-of-mouth access that currently exists for bouldering in the region. It forces you to get to know your community of climbers, learn the ethics, and make friends with the people you live with. And as Paul said, everyone that I've ever seen out at the rocks has been psyched to have another climber around and more than happy to share information about new areas.
There is also another reason these areas are not listed online, access. There is a lot of bouldering around this region, but not much of it has been secured for climbing access and more traffic from less caring individuals would surely start bringing unwanted attention to our recreational pursuits.
