Large, slow-growing, drought resistant tree, reaching heights of 30 ft. Found in washes and rocky slopes at 2,500 ft. elevation and below, and is evergreen except in severely cold winters. As its name implies it has extremely hard, heavy wood, and was utilized extensively by Native Americans for fuel wood, arrowheads, and tool handles.
