Yes, there are sadly some social media posts on the saunas, most don't geo-tag the location, so even if the fact a sauna's existance is maybe known to some, it's a huge barrier to entry without a clear location. Also, you need to follow said accounts in order to discover it - a significant barrier to entry. Posting this on OSM means anyone, everywhere, on any app that consumed OSM data suddenly sees it - people that had no clue it existed suddenly know. It means that a feature goes from mild sustainable use to thousands. Exponential growth. I guarantee you that these saunas will get removed once this happens and it will happen so quick. It's such a shame, I don't understand how you don't see this??

The safety argument I just don't buy. I had a conversation with a friend from Squamish SAR on this exact issue just the other day. You referenced SAR incidents at the site; you'll then likely recall that when SAR pulled the couple from the sauna island after the river level shot up that the formal SAR incident report made no mention of a sauna! That was a very intentional attempt by the organization to respect a local builder's efforts. Moreover, SAR uses their own *private* CalTopo map DB, which includes literally hundreds of secret trails in the Sea to Sky that are not on OSM and hopefully will never be. They really don't need help in this regard. They'd love help from an on the ground volunteering capacity though!!

I don't think what you are doing is a community service or actually benefits the common good. Keeping these things of social media means you introduce a natural filter, a barrier to entry - allowing people who truly want it to put in effort, search for it and find it, feel that reward and be able to enjoy it and actually experience the magical solitude that these types of places provide.

You say this case is borderline, considering the direct appeal from the builder, I'd imagine out of respect for their efforts, taking a more conservative approach would be appropriate.

The builder of the sauna explicitly asked (see posted sign on the sauna entrance) to avoid sharing the place on social media or advertising its location. The only reason it exists is because of thousands of hours of work and planning by someone who welcomes others to enjoy it and share personally, but not digitally. It's utterly disrespectful to disregard this request. I have multiple friends who work in Squamish SAR, they do not need this posted on OSM in order to be effective, it's a rather poor excuse. All it does is draw more users to a totally unmanaged area, which results in more search and rescue calls, environmental damage and again, total disrespect of the builder's time and efforts.
