Spy Rock is a pink granite dome located in the Llano UpliftinMason County, Texas, rising 1,749 feet (533 m) feet above sea level. The peak is located south of Fredonia.[1]
As with Enchanted Rock, Spy Rock is formed of middle Precambrian (1,082 ± 6 million years ago)[2] material. The base of the peak can be reached by the public, but the dome itself is on private property and accessible only with property owner's permission.[3][4] Federal and state statutes, regulations and rules governing trespassing, archeological sites and historic sites apply.[5] The state Game Warden as a commissioned peace officer is authorized to inspect natural resources and take necessary action for the preservation of the resources.[6]
