The Fort Union National Monument was founded on April 5, 1956.
The site preserves the second of three forts constructed on the site beginning in 1851, as well as the ruins of the third.
Also visible is a network of ruts from the Mountain and Cimarron Branches of the old Santa Fe Trail.
Gram and Pops visited here in March 2007.
