Yeah...its not a sport climb like you eluded to earlier. I would say its different than a mountain because people put time and money (bear with me here) into cleaning the route and put in bolts and hangers (thats where the money came from). I've never done anything in the realm of route/crag development, hence me being unsure about this.
With that being said, unless the hangers were stolen, the first ascentionist didn't follow coulee ethics, in establish the route ground up...whatever if it wasn't for organic chemistry I would climbing rather than spraying.
EDIT: Matt, I didn't see your post being I wrote mine. I agree with your final statement. However there lies the problem is exactly how long its been unclimbed or if it has been climbed. I wouldn't really know how to contact. Because it seemed Yoder/Ford didn't know either - because when they listed other projects they put who was working on it.
