In the early 1930's the state of Texas recognized the value of the scenic beauty in the canyons of the Big Bend of the Rio Grande—Santa Elena, Mariscal, and Boquillas. In June of 1944, when Congress established Big Bend as a National Park, it was not only the canyons that made an impression, but the diversity in biological species and incredible geologic forces left open for examination that swayed the Congress to include Big Bend with other National Parks for the people to enjoy.
