Two more large but lightly visited sites are on Cannonball Mesa and in Woods Canyon, both parts of the relatively new Canyons of the Ancients National Monument.
Yucca House was accepted as a National Monument in 1919 and has remained unexcavated the whole time since then. For visitors, it is somewhat difficult to visit as it remains as large rubble mounds overgrown with greasewood without any development for visitors. The area surrounding the site today is used as agricultural land that looks like it might be more productive than the areas on top of Mesa Verde.
The Yucca House site has obvious green marshy spots where springs still bubble to the surface. The setting is interesting as it rests in the shadow of Mesa Verde and may have been visible from the west rim area.
Mesa Verde may appear as an island of cultural development, but the valley areas below were also populated in ancient times. There are isolated preserved sites in the areas away from Mesa Verde but modern development has mostly obscured the remains of that civilization.
It was the first site to receive Federal protection when it was withdrawn from homesteading in 1889. There are no visitor facilities at the Goodman Point Unit and no signs pointing it out. For a visitor, there are some paths to follow and there is some current excavation with some peeks into trenches and piles of collected sandstone bricks. The short brochure says there are 42 different sites to find here, but I think it will appear to most as one very large site.
Logistics of visiting aside, the site is arrayed on a somewhat steep slope above a creek that has year round water and farm fields. Most of the structures are rubble piles with a few intact wall sections near the canyon rim. Most of the area is obscured somewhat by the Pinon and Juniper forest. There are some examples of the use of large boulders as foundations for perched buildings.
