Lower Rock Creek Rd ends near an old Tungsten Mine. It's just up a dead end road I've got to go check out someday. The mine is still there but long-since abandoned.
Just up the road also is the tiny company town of Rovana built for the mine employees.
Rovana was built in 1947 when the US Vanadium corporation acquired the Foreman Ranch near the base of Pine Creek Canyon and built a company town to house those who worked at the nearby Union Carbide mine. By the early 1950s, 135 homes had been built, all on streets that were the names of states matching the letters of Vanadium. Virginia, Arizona, Nevada, Alabama, Dakota, Idaho, Utah and Montana round out the street names. The town name comes from "Ro" for Round Valley and "vana" for US Vanadium.
Pine Creek Rd is paved for 10 miles to the abandoned Tungsten mine at the base of the Sierra Range at the 8000 ft level. The Union Carbide Tungsten Mine began operation in 1937 and operated through 1990. Tungsten is a heavy metal used to make things harder, it is super dense and almost impossible to melt.
Tungsten is used in hardening drill bits, munitions and heavily used in light bulb filaments since its melting point is well above 6000 degrees.
The Union Carbide Tungsten mine was known as an upside down mine. Tunnels at the base of the Sierra Nevada went 2-1/2 miles straight level into the mountain range and then extended upwards. Elevators lifted the miners up 2700 feet, into the center of the mountain, then dropping the ore down, rather than tunneling down into the earth like most gold mines in the Sierra Foothill Mother Lode regions.
Ore was then dropped into open vertical shafts over 1400 feet high where the rock tumbled down a hole deeper than the Empire State Building is tall. The ore was then processed to extract the tungsten, which resembles a white sugary substance when refined.
Tungsten is one of the heaviest elements: A 4-inch block of the metal, which can easily fit in the palm of your hand, weighs 41 pounds.
A 14x14 inch cube of Tungsten was recently sold for $250,000.
That 14"x14" cube of Tungsten weighs 2000 lbs.
