First opened to the public in October, 2005, Government Canyon State Natural Area (GCSNA) preserves 12,244 acres (49.5 km2; 19.1 sq mi) of rugged hills and canyons typical of the Texas Hill Country. It is designated a Natural Area, rather than a State Park, and therefore the primary focus is maintenance and protection of the property's natural state. Accordingly, access and recreational activities may be restricted if the Texas Parks & Wildlife Department (TPWD) deems such action necessary to protect the environment.
The reserve is located in northwestern Bexar County, and protects a large, relatively pristine tract of Hill Country terrain, numerous and diverse species of plants & wildlife, the upper Culebra Creek/Leon Creek watershed, and a critical aquifer recharge zone for the San Antonio Water System.[2]
In September, 2009, the City of San Antonio transferred 3,000 acres (12 km2) of land to the TPWD for inclusion in the Natural Area, specifically to support long-term protection of the Edwards Aquifer, and thereby increasing the total acreage within the reserve from 8,783 acres (35.54 km2) to 11,783 acres (47.68 km2). Most recently, in April, 2013, an additional 461 acres (1.87 km2) were added to GCSNA through a combination of funding from the City of San Antonio, Texas Parks & Wildlife, and a US Fish & Wildlife Service endangered species grant, which brought the reserve's total area to 12,244 acres (49.55 km2).
History
Theropod trackway
110 million years ago, during the Cretaceous period, much of Texas was covered by a shallow sea. As the sea receded, dinosaurs walking in the moist mud left behind tracks in the mud. Sediment filled the tracks and the mud turned to limestone. The sediment washed away and trackways are visible when conditions are dry. There are three main trackways made by theropods and sauropods, which researchers believe to be Acrocanthosaurus and Sauroposeidon.[3]
Archaeologists believe Native Americans occupied the area up to 8,000 years ago as evidenced by a burnt midden uncovered in the park. In the early 1850s, government surveyors laid out a military supply route through this area to western frontier forts. The locals called it the “government road” that was being built through the “government’s canyon” giving the park its name. European settlers came to the area around the 1860s. The clear springs, fertile floodplains and lush grasslands supported their farming and ranching activities. An old house and barn still exist as a reminder of the park's heritage.[4]
GCSNA is open to the public 4 days (Fri. – Mon.) each week, weather permitting, and offers 40 miles (64 km) of hiking/biking trails,[6] with over 500 feet (150 m) of elevation change found within the reserve's boundaries. Entrance fee: $6 per adult; children 12 and under, free. Beginning Friday, October 5, 2012 the Natural Area will allow overnight camping on Fridays and Saturdays in the "Front Country" section only. There are regular walk-in 50–60 yards (46–55 m) campsites, and two group walk-in campsites that allow up to 16 persons per site.
TPWD urges all visitors to respect the LEAVE NO TRACE set of wilderness ethics when visiting the Natural Area: 1) Plan Ahead and Prepare, 2) Travel on Marked Trails Only, 3)Always Dispose of Waste Properly, 4) Leave Behind What You Find, 5) Never Build An Open Fire, 6) Respect All Wildlife, and 7) Be Considerate of Other Visitors.
