International Obscura Day is a celebration of exploration and discovery, with more than 160 curious and awe-inspiring real-world expeditions taking place in 35-plus states and more than 25 countries, all on a single day. Right here in Idaho, you can get in on the fun with a tour of America's only officially "weird" national monument, Craters of the Moon.
