History of Kemmerer

Early Discoveries and Mining

In 1843, explorer John C. Frémont found coal in the Kemmerer area. Later, in 1881, the Union Pacific Coal Company opened the first underground coal mine. This happened after the Oregon Short Line Railroad was built nearby.

Founding the City

Patrick J. Quealy, who came from Ireland, founded Kemmerer in 1897. He was a leader at the Kemmerer Coal Company. He named the company and town after Mahlon S. Kemmerer, a rich coal businessman from Pennsylvania. The company's mine was about 6 miles (10 km) south of the original town.

In 1950, the mine changed to strip mining, which is digging coal from the surface. It became one of the world's largest open pit coal mines. Today, it still operates and produces about 5 million tons of coal each year.

Growth and Businesses

Patrick J. Quealy sold land in Kemmerer instead of leasing it. This allowed many independent businesses to start. His company also provided electricity to the town. Quealy was also the first president of the First National Bank, which opened in 1900.

A famous store, J. C. Penney, started in Kemmerer in 1902.

Future Energy Plans

TerraPower, an energy company, chose Kemmerer for a new type of power plant. This plant will use a special kind of nuclear reactor called a molten salt reactor. It can produce 345 megawatts of power and even boost it to 500 megawatts. This helps it work well with other energy sources like solar or wind power.

In June 2024, work began to prepare the site for this plant. The project is expected to cost about $4 billion. The U.S. Department of Energy is helping to pay for half of it, and Bill Gates is contributing $1 billion.

Geography of Kemmerer

Kemmerer covers about 7.81 square miles (20.22 square kilometers). Most of this area is land, with a very small amount of water.

The Fossil Butte National Monument is a cool place to visit. It's about 15 miles (24 km) west of Kemmerer, right on U.S. Highway 30.

Kemmerer's Climate

Kemmerer has a climate known as "warm-summer humid continental." This means it has warm summers and cold winters. The hottest temperature ever recorded in Kemmerer was 99°F (37°C) on July 12, 1990. The coldest was -39°F (-39°C) on December 22, 1990.
