That's a fantastic find. I imagine some standard CV tool can spot this since the holds are grid-aligned. We should probably have something like that. It's crazy how good human pattern-recognition can get when trained on things. What a spot by you.

Also, by the way, where is the photo on your about page: https://images.squarespace-cdn.com/content/v1/60f40aa1942bba...

I feel like it's Crater Lake, Oregon, but considering where you live it's probably somewhere in Switzerland. Looks lovely.
