Rockpile Mountain Wilderness

Rockpile Mountain Wilderness, the smallest in Missouri, is located in a heavily forested part of the Saint Francois Mountains and nearly surrounded by private land. Named for a human-made circular granite pile atop Rockpile Mountain, the elevations range from about 1,300 to 520 feet. The southwestern boundary is the Saint Francis River, lined with limestone bluffs and caves. Other than the river, no year-round water sources exist, except in five ponds built before wilderness designation to trap intermittent springwater and provide watering holes for wildlife. Heavy rains can create temporary streams cascading through narrow gorges.
