Hueco Tanks State Park and Historic Site

Hueco Tanks State Park and Historic Site is an 860-acre (350 ha) state park, National Historic Landmark and National Register of Historic Places site in El Paso County, Texas, United States approximately 32 miles (51 km) northeast of central El Paso. The land was obtained from the county by special deed on June 12, 1969, and by purchase of 121 acres (49 ha) additional land on August 10, 1970. This site was opened to the public in May 1970 and is managed by the Texas Parks and Wildlife Department. The park is named for the large natural rock basins or "huecos" that have furnished a supply of trapped rainwater to dwellers and travelers in this arid region of west Texas for millennia.

Hueco Tanks is an area of low mountains located in a high-altitude desert basin between the Franklin Mountains to the west and the Hueco Mountains to the east. Hueco is a Spanish word meaning "hollows" and refers to the many water-holding depressions in the boulders and rock faces throughout the region. Due to the unique concentration of historic artifacts, plants and wildlife, the site is under protection of Texas law; it is a crime to remove, alter, or destroy them.

The park consists of three syenite (a weak form of granite) mountains. It is culturally and spiritually significant to many Native Americans. This significance is partially manifested in the pictographs (rock paintings) that can be found throughout the region, many of which are thousands of years old.
