Fort Union National Monument
was created in 1954 but remains relatively unknown, despite being just 8 miles from Interstate 25 in northern New Mexico. The preserve contains the remains of a large 19th-century fort, surrounded by flat prairie typical of this part of the state, in places still marked with ruts from wheels of wagons traveling along the Santa Fe Trail
. The site is quite extensive, containing several dozen original buildings, and a walk of about a mile is required to view all areas. The nearest major city is Las Vegas, 30 miles south.
