Lenticular clouds are stationary, saucer-shaped clouds that form when moist air is pushed over large obstructions. As the tallest mountain in the Cascade Range, Mount Rainier in Washington is a great place to see these unique cloud formations. If you don’t care about the clouds, you can still enjoy amazing recreation, wildlife watching and cultural history at Mount Rainier National Park. Photo by Jacklyn Fraizer (www.sharetheexperience.org)
