Big Bend is home 1,200 species of plants, over 450 species of birds, 75 species of mammals and 56 species of reptiles. (We’re not sure how many of those are snakes, if you’re wondering.)

Because of its remote location, Big Bend also has among the darkest skies ever measured in the contiguous US. So tonight, the only light you’ll likely see is the glow from 75 birthday candles – and a few million stars.
