Mount Antero is prized for its gemstone deposits and has one of the highest concentrations ofaquamarine in the country. There are several active private mining claims being exploited on Mount Antero and surrounding peaks.
The peak is located due south of the more visually prominentMount Princeton. Mount Antero is one of the most prominent peaks of the Sawatch Range, rising an impressive 7,200 feet (2,200 m) above the town of Salida, Colorado to the southeast. There are two popular climbing routes on Mount Antero. The generally accepted hiking route is from the east starting at the Browns Creek Trailhead and paralleling Little Browns Creek to its upper reaches where it crosses Forest Road 1A, then following the road near to the summit. The other route, which begins near the ghost town ofSt. Elmo, follows the same forest road from the north up Baldwin Creek. This route has heavy mining and tourist traffic in fair weather during the summer months.
The peak was surveyed by thePike Expedition in 1806. A forest service sign at the Browns Creek trailhead commemorates the expedition camp at the eastern base of the peak.
