Fort Whoop-Up is also the name of a replica site and interpretive centre built in Indian Battle Park.

[6] When it was finished, Fort Whoop-Up was "a squared timber post complete with a stockade, cannon-mounted bastions, loopholes for firing rifles, and three wickets for trading with the aboriginals.

[9] The spread of American traders from Fort Benton north into Canada was spurred by the enforcement of prohibition in Montana in 1869.

Traders, like Healy and Hamilton, brought their stockpile of whisky to Canada to continue their lucrative trade.

The outlaws of Fort Whoop-Up and surrounding areas—combined with the supposed flying of an American flag over Canadian territory—contributed to the formation of the North-West Mounted Police (NWMP).

The NWMP arrived at Fort Whoop-Up in October 1874, with the task of establishing Canadian sovereignty in the territory and controlling the alcohol trade.

In 1875, the NWMP rented a room from the owners of the fort, Healy and Hamilton, and established a post there.

Since then, various new exhibits have been unveiled, including the Thunderchief Collection, showcasing artifacts from the local Blackfoot culture; the Shockley Firearms Gallery; and Voice from the Past, an audio program that enables visitors and school children to receive guided tours year round.
