Spilling Thought: Today, @yosemitenps is taking over our Instagram account, sharing stunning photos from the park. This dramatic shot of #YosemiteFalls was taken last month as the early morning fog began to burn off the valley floor. Yosemite Falls, one of the world's tallest #waterfalls, is actually made up of three separate falls: Upper Yosemite Fall, the middle cascades and Lower Yosemite Fall. The best time to see Yosemite Falls is November through July with peak flow typically in May. Photo by Kari Cobb, #NationalPark Service.
