Here's another image from the wonderful 2013 Big Bend Calendar our friend, Derrick Birdsall is selling to celebrate both Big Bend National Park and Big Bend Ranch State Park, AND send a portion of the profits back to our own Texas Mountain Trail!

Big Bend National Park has been cited by the International Dark-Sky Association as one of just five international dark sky parks earning its gold-tier level for being nearly entirely free from light pollution.
