History
Mining was conducted at the site from November 1939 to September 1955 using a room and pillar method. The Genwal Coal Company resumed mining there in 1983. At that time the mine produced between 100,000 and 230,000 tons (91,000–209,000 t) of coal each year. NEICO purchased the mine in 1989 and the next year IPA purchased 50% interest. By 1991, a continuous haulage system was used helping production surge to 1 to 1.5 million tons (900,000–1,400,000 t) each year.
Genwal Resources, Inc. acquired the mine in March 1995 and a longwall was installed the same year into the mine. The installation of the longwall nearly doubled the capacity of the mine. A new longwall was purchased two years later which increased the capacity further to 3.5 million tons (3,175,000 t) per year. To handle the increased capacity, a new loadout facility was built at the mine. Additional federal leases were expected to extend the life of the mine and new portals on its south side were slated to be installed to expand access options. Mine owners had informed the state of Utah they planned to close the mine in 2008.

“The history of all Magazines shows plainly that those which have attained celebrity were indebted for it to articles similar in natureto Berenice—although, I grant you, far superior in style and execution. I say similar in nature. You ask me in what does this nature consist? In the ludicrous heightened into the grotesque: the fearful coloured into the horrible: the witty exaggerated into the burlesque: the singular wrought out into the strange and mystical.”
—Edgar Allan Poe (1809–1849)
