What is the name of the historic fort in Fort Bridger, Wyoming, and when was it first constructed?

Fort Bridger is an important historic site in Wyoming, USA, which served as a trading post, military installation, and a stop for travelers during the westward expansion in the 19th century. The fort is named after its founder, mountain man and trader Jim Bridger.

The original Fort Bridger was established in 1843 by Jim Bridger and his partner Louis Vasquez as a fur trading post. However, it was soon sold to the Mormons in 1853, who used it as a supply post for their migration to Utah. The Mormons added new buildings and expanded the fort, making it a major hub for travelers and settlers heading west.

The fort was taken over by the US Army during the Utah War in 1857, and it became an important military installation in the region. During the Civil War, it served as a supply center for Union troops in the area. In 1878, the army abandoned the fort, and it was sold to the public. Today, the fort is a state historic site, with several original buildings and reconstructed structures that provide a glimpse into the life of early settlers in the region.
