Big Bend National Park, Texas, USA

Today we celebrate the 88th anniversary of Big Bend National Park in Texas. Since this humongous park was established in 1935, it has welcomed nature lovers and adventure seekers. The park's southern boundary is marked by the Rio Grande that separates Texas and Mexico. If you look at a map of the park and the river, it's clear how it got its name!
