Back in the day, Fort Caspar was a military base along the historic Oregon Trail and Pony Express. Today the Fort Caspar Museum and Historic Site features reconstructed buildings, including a stockade and a replica of the Mormon ferry that operated between 1847 and 1849. Inside the Interpretive Center, you can visit the exhibit and learn more about the history of the area, the early pioneers, and a section of the Guinard Bridge. Latter one was used by pony riders to cross the North Platte River.
