The site of the 1849 U.S. Calvary post, was inhabited by people and wildlife for thousands of years because of its protected location. Fort Inge (Camp Leona) is on the east bank of the Leona River a mile south of Uvalde in southern Uvalde County and was establised as a part of the first federal line of frontier forts in Texas. The site is dominated by Mount Inge, a 140-foot volcanic plug and archeological evidence indicates the place has been intermittently occupied since the Pre-Archaic period, about 6,000 B.C.
