1863 | Utah's first mining claim is filed in Bingham Canyon west of Salt Lake Valley.

1868 | In late October, soldiers climb over the mountains from Big Cottonwood Canyon to the Park City area and find silver. As the snow is swirling and a storm brewing, they mark the outcropping with a bandanna on a stick and return in the spring. The first mine is named Flagstaff. Park City will become known not only for its silver, but for lead, zinc and gold. The Flagstaff Mine is the first to ship ore from the area.

1872 | George and Rhoda Snyder name the area Parley's Park City, soon shortened to Park City. The discovery of exceedingly rich silver ore (400 ounces to the ton) leads to the opening of the Ontario Mine and starts a boom town atmosphere in Park City.

Water in the mines is a continuing problem in spite of numerous underground pumps. The Cornish Pump, a machine 30 feet high with a 70-ton flywheel, is imported from Philadelphia by freight wagon. It pumps water from 1,000 feet below the surface in the Ontario Mine, taking out over 4 million gallons of water a day. Later, drain tunnels will replace pumps.

Three quarters of the town is gone, 500 are homeless, $1 million in property is lost. Gone is the grand new opera house built at a cost of $30,000 and open less than three months. Seventeen volunteers leave to fight in the Spanish-American War which forces the price of silver upward. 

1899 | The town is rebuilt in one and a half years! The new buildings are more substantial - many are built of brick and stone to withstand fire. George Wanning's saloon is the first to be rebuilt. 

1901 | Silver King aerial tramway uses buckets to bring ore down to town, lowering transportation cost to 22 cents a ton from $1.50 per ton when hauled by horse and wagon.

On July 15th, 34 men from the Daly West Mine die in an explosion of a large underground store of dynamite, which also produces fatal fumes.
