What US city is home to Franklin Mountains Stare Park?

Franklin Mountains State Park is a Texas state park in El Paso, Texas, in the United States. Park headquarters are located at an elevation of 5,426 feet (1,654 m) with the highest peak reaching 7,192 feet (2,192 m). It is the largest urban park in the nation lying completely within city limits, covering 24,247.56 acres (9,813 ha). Franklin Mountains State Park is open year-round for recreational hiking, mountain biking, picnicking and scenic driving and vistas.

The Franklin Mountains are most likely named for Benjamin Franklin Coons, who in 1849 purchased a ranch in what is now El Paso. At first known as Coons Ranch, by 1851 the settlement took on Coons' middle name and was called Franklin. Despite the town being officially named El Paso in 1852, the locals continued to call it Franklin throughout the 1850's. Pictograms and mortar pits confirm a human presence in the mountains dating back more than 12,000 years.

The mountains are the southernmost tip of the Rocky Mountains in the U.S. The Precambrian rocks atop North Franklin Mountain are "the highest geological structure in the state of Texas." The highest peak is North Franklin Mountain at 7,192 feet (2,192 m). The mountains are composed primarily of sedimentary rock with some igneous intrusions. Geologists refer to them as tilted-block fault mountains and in them can be found billion-year-old Precambrian rocks, the oldest in Texas.
