Abstract:

In April of 1983, the Thistle slide blocked the flow of the Spanish Fork River and traffic using the Denver and Rio Grande Western Railroad, U. S. Highway 89, and U. S. Highway 50 and 6. This paper gives an account of the method used in draining the 78,408,000m**3 of water that accumulated behind the slide. In total, 684m of tunnel would be driven, 62m of raised vertical shaft completed, and 23,000m**3 of cut excavated.
