Amistad National Recreation Area - http://www.nps.gov/amis
A splash of blue stands out against limestone cliffs. The honking of a great blue heron, interspersed with the descending trill of a canyon wren, can be heard off in the distance. This landscape, which at times appears stark and desolate, comes alive with color after a rainstorm. Amistad is a land of contrasts...and of hidden treasures. The same water that draws people to boat and fish today, sustained over 300 generations of hunters and gatherers. They left behind a record of their existence through colorful rock art panels, bits of tools, and fibers preserved for thousands of years by the arid desert climate.
Situated on the United States-Mexico Border, Amistad NRA is known primarily for excellent year round, water-based recreation including: boating, fishing, swimming, scuba diving and water-skiing. Amistad NRA also provides opportunities for picnicking, camping and hunting. The reservoir, at the confluence of the Rio Grande, Devils and Pecos rivers, was created by Amistad Dam in 1969. In addition to excellent recreation, this area is rich in archeology and rock art, and contains a wide variety of plant and animal life.
