Engineering Associates is working with the Abandoned Mine Lands Division of the Wyoming DEQ to mitigate hazards on U.S. Forest Land. One such site is the Walker Mine located in the Bighorn National Forest above Dayton, WY. The site consisted of a vertical shaft approximately thirteen feet deep with a historic shaft house still mostly intact above the shaft. This site was unique in that the pathway up to the site was also part of the historic mine road that connected the shaft with the miners’ camp. As such, no machinery could be brought onto the historic pathway. Instead, a different kind of horse power was used. Horses and mules transported materials up the hill to the shaft house as well as assist the contractor in moving soil and rocks from the spoils pile to the shaft house. It was a challenging effort that echoed the history of Wyoming!
