Moonshine Boulder 

I agree with Nick's comments and assure you that he is aware of and respects the nebulous history of bouldering out there. I do not think secrecy is a sustainable, long-term plan for protecting resources be it camping or climbing. I think that perhaps the argument of secrecy is at heart derived from a more selfish goal of keeping a location, area, boulder, etc. to yourself and/or your group of cronies. Perhaps secrecy may delay an influx of people, but I doubt that any amount of online spraying and posting will drag hoards out to Unaweep for climbing and/or bouldering. As for dealing with issue of people trashing the land out there, I believe whole heartedly that climbers are not to blame for the majority of damage. There have been hobo villages and all manner of people destroying the land out there; from paintballing to high school partying. These sorts of issues are better dealt with explicitly. There is an open and fruitful dialogue between the BLM and concerned climbers about land use and the issues of vandalism and misuse. With the increasing popularity of climbing at a global level, providing the correct information and making every effort to facilitate educating those new to the sport/outdoors should be of the highest priority.
