Casper is a city in Wyoming, United States. It is the county seat of Natrona County, Wyoming. Casper is the second-largest city in Wyoming. About 59,000 people lived there in 2020.

Casper is often called "The Oil City." It has a long history tied to oil and cowboy culture. This goes back to when the nearby Salt Creek Oil Field was developed. The city is in east-central Wyoming, right on the North Platte River.

Discovering Casper's Past

Casper was founded east of an old military post called Fort Caspar. This area was popular with European settlers in the mid-1800s. Many people traveled through here on trails like the Oregon Trail, California Trail, and Mormon Trail. Several ferries helped people cross the North Platte River.

In 1859, a man named Louis Guinard built a bridge and a trading post. This made travel easier for people passing through. The government also sent soldiers to protect telegraph and mail services. Lieutenant Colonel William O. Collins led these soldiers.

Native American attacks increased after 1864. More troops came to the post, which was then called Platte Bridge Station. In July 1865, Native American warriors killed Collins's son, Caspar Collins. Three months later, the post was renamed Fort Caspar in his honor.

In 1867, the soldiers left Fort Caspar. They moved to Fort Fetterman further down the North Platte River. However, the town of Casper itself was settled in 1887. It became an official town a year later. Developers thought it would be a key stop for the Wyoming Central Railway.

The original plan was to build the town a few miles east. A homesteader named Joshua Stroud lived there. The Pioneer Town Site Company set up the site in 1888 and called it Strouds. But the name Casper soon became more popular. The name "Casper" comes from Fort Caspar and Caspar Collins. It's spelled "Casper" because of a mistake when it was officially registered.

Casper became an important trade center. It was a starting point for people involved in the Johnson County War. This was because the train carrying these men stopped in Casper. The city also saw many visitors during the solar eclipse of August 21, 2017. This was because Casper was in the path where the sun was completely blocked.
