1. Pine Creek Mine Marker
Inscription. West of this spot, gold was discovered in the Pine Creek drainage by Civil War veterans. It was not until April, 1916, when tungsten was discovered by four men: O.E. Vaughn, A.E. & C.C. Beauregard, and James Sproul on their claims, Blizzard 1, 2, 3 and 4, high on the mountain. Years of development and production went by and the mine was acquired by U.S. Vanadium, a division of Union Carbide Corp., on May 14, 1936. After more development, this mine became the world’s largest tungsten mine and is now known as “the Mine in the Sky”.
