So I went to a route today that doesn't have a name and isn't in any of the guidebooks. I talked to a guy at the local pro shop and he knows the route, but says it doesn't have a name. Can I just name it or should I seek out the FA and ask him if it's okay with him first? What's the climbing etiquette on that?

Definitely try to find the FA and see if they had a name for it. That's always the proper etiquette. But there are a lot of climbs IN guidebooks that are named "unnamed" or "unknown." Sometimes we just have to live with it. That said, I gave a name to one of my route submissions that like yours, seems to have no name and is not in any of the guidebooks. But I made it clear in my description that it was simply what I called the route, as opposed to an official name. Hopefully, one of these days, I'll be able to get more history on the area and update the info.
