The Uwharrie Mountains are a mountain range locate in North Carolina, USA. The range lies in the counties of Randolph, Montgomery, Stanly, and Davidson, although its foothills stretch into Cabarrus, Anson, and Union counties. Formed approximately 500 million years ago, the Uwharries are one of the oldest mountain ranges in North America. Thought to have once peaked at some 20,000 feet, erosion has worn the Uwharries to a peak height of only 1,119 feet (341 meters) above sea level, as measured by the NC Geodetic Survey. The highest point in the range is High Rock Mountain, located in southwestern Davidson County. Once a coastal mountain range, plate tectonics has slowly raised the eastern seabed, until today the Uwharries are located in the Piedmont section of North Carolina over 150 miles from the coast.
