Dome sweet dome

There's a reason why famed American photographer Ansel Adams fell in love with Yosemite National Park: vistas like today's image of Half Dome. The park, in central California's Sierra Nevada range, has been a popular destination for artists, mountaineers, settlers, and nature lovers since the mid-1800s. To protect it from logging and overgrazing by cattle, Congress designated Yosemite a national park on this day in 1890. It's one of the most visited parks in the US, with more than 3 million visitors a year.
