Somewhere within the area seen from this hill, France in the reign of Louis XV maintained a log fort to facilitate trade with the Kansa Indians and the Spanish in New Mexico. It was named for its founder Gov. Vaudreuil-Cavagnial of Louisiana. It was abandoned when Louisiana was ceded to Spain. Lewis and Clark visited the remains of the fort on 2 July 1804.
