22. Thor’s Well – Yachats, Oregon
Not many people know the site called “Thor’s Well,” but it’s one of those natural formations you’ll never forget for the rest of your life. It’s a natural saltwater fountain that’s entirely powered by the ocean tide. The best time to witness the “well” inaction is an hour before high tide or an hour after high tide (via Buzzfeed). You should exercise caution if you decide to get close to the “well” since it can be very slippery and you don’t want to fall in (via Buzzfeed).
