Big Bend National Park covers 801,163 acres, is open year round, 24 hours a day, seven days per week, but plays host to an average of less than 350,000 visitors each year. The park includes about 244 miles along the Rio Grande River.
Park boundaries protect the largest amount of Chihuahuan Desert topography and ecology in the US, with more than 1,200 species of plants, 450 species of birds, 56 species of reptiles and 75 species of mammals (including mountain lions and bears), many of these species are rare.
The Distant Past
The park has petrified trees and artifacts of prehistoric cultures which archaeologists say date back 9,000 years, recorded in pictographs and petroglyphs on rock walls and mortar holes along the river's bank.
The park is vast and varied. Besides the camping, hiking, backpacking, fishing and sightseeing pastimes, Big Bend has great cross-country and snowshoeing routes from November through March, fantastic wildflower displays in spring and early summer and world-class bird watching (170 species) between May and October. In August or September, crowds are gone. Floats on the Rio Grade offer a unique perspective to the country.
Cactus, which efficiently collect water and then gives it up sparingly, is joined by desert annual plants which survive by staying dormant until rains come to the desert, sometimes more than a year, then germinating when water is available and progressing through their life cycles to insure future generations. Often, the seeds are coated with chemicals prohibiting germination until sufficient water is present to wash the coating off. When they are ready, they move more quickly through life stages than do plants in temperate environments.
Sedimentary rocks, laid down by seas which invaded the area millions of years ago, predominate the Big Bend landscape in complex formations of limestone, sandstone and shale. The mountains and the 40 mile wide trough with attending cliffs in Big Bend were created by uplift and sinking along fault lines, respectively, millions of years ago. Volcanoes also chipped in to create the setting.
