Labor Day doesn't exist in Park City, because the first Monday of September is always called  Park City Miner's Day.

In Park City, the spirit of Labor Day translates to the spirit of mining.  One of my favorite holidays, our town celebrates the Labor Day Holiday as a remembrance of our town's historical mining roots - thus the name, Park City Miner's Day.  A day's worth of traditional events are planned to mark Miner's Day in Park City on Monday, September 2.  There is no better way to start off the day than with a breakfast at the City Park.  And then for those a bit more energetic, they can run in a 5K run, catch the "Running of Balls" followed by a funky parade down the town's Main Street.  As with the 4th of July, the crown then moves to City Park for music throughout the day, and one of the countries only mucking and drilling competitions.
Miner's Day

The Running of the Balls is the Rotary Club of Park City's biggest fundraiser of the year. People can purchase a ball for $5 or they can buy five for $20.  The balls will be released at 10:45 AM, 15 minutes prior to the Main Street Parade. 
Miners Day

Our mucking and drilling competition is famous.  It draws competitors from Utah and surrounding states, involves miners who dump rock in a mucking machine (muck is the rubble made after rock is dynamited) and drill concrete blocks with massive pneumatic drills. Both are timed events.  I'm sure there are very few people that have actually seen this equipment and they are mostly children of either fathers or grandfathers who were involved in the mines.  Park City rocks when it comes to this competition and rarely loose.   

The first Miner's Day, which then was called the Miner's Union Day, was celebrated June 13, 1898, according to Sandra Morrison, executive director of the Park City Museum. By the 1940s, the town transformed Labor Day into Miner's Day.  In its heyday, Park City's mines extracted $400 million in silver ore in the late 1800s and early 1900s, creating 23 millionaires.

The price of silver then bottomed out in the 1930s. In 1946, the first ski chair lift opened at what is now Deer Valley, and the ski industry began to boom in the 1960s.
