Chaparral's post office was established May 24, 1894 and was discontinued December 31, 1917. There were about twenty businesses lining the streets in Chaparral all under the control of Sheriff Mike Enright. Chaparral owed its existence to the Little Jessie and McCabe mines nearby. The rise of McCabe saw the fall of Chaparral and the post office finally closed in 1917. Today, nothing remains but rubble and the occasional hole in the ground.
