The Black Mountains are a mountain range located in the southern part of Inyo County and northern San Bernardino County, California, in the southeast part of Death Valley National Park.

The Amargosa River turns south-southwest, around the three sub-ranges, then northwest into Death Valley.

The Owlshead Mountains are to the south across the Amargosa River and its steep descent into Death Valley.

The range reaches an elevation of 6,384 feet (1,946 m) above sea level at Funeral Peak.

Around 1914 he built the Death Valley Railroad to primarily serve the newer Ryan C. Mine above it within the Black Mountains, with a spur to the Lila C. tracks.
