Dillon Pinnacles, Curecanti National Recreation Area
Three reservoirs and surrounding lands make up this recreation area in western Colorado. It is a landscape of tradeoffs; natural and human made features exist together. Geologic wonders are abundant from the sagebrush shrublands to forests. Visitors can experience the park year-round on both land and water.
