President Woodrow Wilson proclaimed the site a National Monument on December 19, 1919, after the donation of 9.5 acres (38,000 m2) of land on July 2, 1919 by a private landowner. An additional 24 acres was donated by Hallie Ismay in the late 1990s. It was one of many research national monuments designated during that era to preserve the ruins, plants and animals in the Yucca House area. Hallie Ismay, benefactor of the additional land in the 1990s, was an unofficial steward of the Yucca House site for 62 years.
As a National Park Service historic area, the park was administratively listed on the National Register of Historic Places on October 15, 1966. The site is managed by Mesa Verde National Park.
Currently, there are no true interpretive features, facilities or fees at Yucca House. See the Visitor Guide for directions to the remote location. Parking space is limited and roads may be difficult immediately following rains or snowmelt. (Wikipedia)
