Newcastle, United States. The Accidental Oil Company operated this oil well attraction in eastern Wyoming starting in 1970. The primary draw was a hand dug 24 foot-deep oil well, an excavated underground cavity that visitors could walk into through a lighted tunnel, and admire from a 58 foot-long viewing gallery.  Topside was a pump with a crank so people could pump oil out by hand. There was also old oil field equipment on display, and a 10,000 barrel metal oil tank, which was turned into a gift shop called The Gift Tank, with paneled walls and chandeliers. The facility closed some years ago, and is abandoned.
