Tim Twichell's Mountaineer Pics


The Mountaineer, like so many other massive shovels, spent it's lifetime working the coal fields around Cadiz, Ohio. Officially designated the "Marion 5760, the mountaineer was assembled in the mid-1950's, and began her working life in January 1956. She continued to work the area, until 1979, when she was parked. For nearly ten tears she sat idle before the decision was made to dismantle her. The machine, a local celebrity, gained regional ( if not national) attention in the early 70's, when after completing work in one coalfield, she had to be moved across a major interstate highway. After being granted permission by the state of ohio, coal company employees cover the interstate with about 30 feet of dirt, walked her across and then cleaned up the highway. Amazingly, all of this work was completed in a single night.
