About that location...

Marathon, Texas is located in a remote section of West Texas known as the Big Bend Region, in Brewster County which fortuitously is the largest county in the country with the lowest population density. Brewster county is now part of a 3-county Dark Sky Reserve! It is situated in what is known as, the Great Marathon Basin, and surrounded by mountains which protect it from light intrusion from neighboring towns.
