Grandview Mine

The Grandview Mine, also known as the Last Chance Mine, was operated by Pete Berry from 1892 until 1901 in what later became Grand Canyon National Park. The Grandview Mine Historic District includes what remains of the mine shafts and machinery as well as the ruins of a stone house and sleeping shanty. Physical evidence, including low stone walls and construction debris, suggests that several wood structures were also originally present on the site.

In 2009, the mines were gated to protect bat roosts, support on-going bat research, preserve historic mine resources, and promote visitor safety. The gating project was done by Mine Gates, Inc., with support from Grand Canyon National Park, Bat Conservational International, and Freeport-McMoRan. Details of the mine site, as well as manufacturing and installation of each bat gate are documented on the MineGates site
