One of the largest open-pit mines

Kennecott Copper Mine

Major source of copper ore

9,000 Feet
The Kennecott Copper Mine in Utah is a major source of copper ore and one of the largest open-pit mines in the world. Located just outside of Salt Lake City, this mine has been mined since 1906 and provides jobs to more than 1,200 people each year. The mine produces nearly two million tons of copper every year, making it the third-largest copper mine in the United States.

One of the most notable things about this mine is its size. It is over 4,000 feet deep and 2.5 miles wide – enough to fit 25 football fields within its walls! In total, an estimated 14 billion tons of ore have been mined from this site since its opening. The ore is extracted from the ground through a process called open-pit mining. This method creates large pits in the ground and involves blasting, drilling, and hauling away layers of soil and rock to access the ore underneath.

Kennecott has been around for over a century, but it wasn’t until recently that it became an attraction for visitors. The mine offers tours that give visitors an up-close view of the operations and a chance to learn about the history of copper mining in Utah.

The Kennecott Copper Mine is also home to some interesting wildlife. Several eagle species live in the area, including golden eagles, bald eagles, and red-tailed hawks. In addition to the birds, various species of mammals also inhabit the area, such as bobcats, coyotes, and mule deer. Keeping these animals safe is a priority for the mine operators – noise reduction efforts have been put in place to keep wildlife away from operations at all times.

The Kennecott Copper Mine in Herriman, Utah is an important part of the local economy, providing jobs for the community and contributing to the state’s GDP. It also provides a valuable natural resource – copper ore – which is used for electrical wiring and in many other industrial processes.


The geology at the Kennecott Copper Mine is fascinating, as it contains several different types of rocks. The main type of rock in this area is porphyry, which consists of interlocking crystals and often has reddish-orange hues. It is thought that this rock formed from molten magma over time due to volcanic activity in the region. Other types of rock found in the area include limestone and sandstone.


The first copper ore was discovered in the Kennecott Copper Mine area in 1903 and mining operations began shortly thereafter. The mine quickly became a major producer of copper, producing up to 60% of the world’s supply at its peak. Operations at the mine continued until 1938 when they were suspended due to World War II. After the war, the mine was reopened and stayed open until 1985.

Today, the Kennecott Copper Mine in Herriman, Utah is still open to visitors and offers tours of its facilities.
