A beautiful pearly mussel, which probably gives the names to the streams and the Post, can be found anywhere along the banks.

The Concho River is historic. For generations, people and wildlife have called this region home and left traces of their presence. Legends abound, from Native traditions found at the Painted Rocks, through the earliest written records of miracles (The Lady in Blue), hardships (the earliest frontier settlers), and even armed conflict (Fort Concho). People have ultimately thrived and built lives worthy of remembrance and study. At the same time, the ecosystem has served as an excellent home to many unique flora and fauna, including the Tampico Pearlymussel, host of the world-famous Concho Pearl. Countless people, plants, and animals have cherished the waters of the Concho.
