Large mining-era relic collapses in Deer Valley

A large remnant of Park City’s silver-mining days collapsed in Deer Valley early Friday, City Hall said, a scenario that had long been a concern to Park City leaders as relics from that era age.

Investigators from the Park City Building Department said the collapse was a result of several factors, including the saturation of the soil, the instability of the ground at the location and a mild winter without a deep frost.

Jason Glidden, a spokesperson for City Hall, said the shaft of the Daly-West Mine started to cave in on the sides. The derrick then collapsed, he said. The site is outside the Montage Deer Valley.

Glidden said the Jordanelle Special Service District, a Wasatch County water provider, owns the shaft. A representative from the district was not immediately available.

Park City was founded as a silver-mining camp and the industry drove the local economy into the middle of the 20th century. As the price of silver dropped, the silver mines were shuttered and the ski industry eventually took hold. Numerous mining relics remain in the mountains, though.
