For some reason, I missed this on my several previous trips to Grand Canyon. It is located on the east entrance, which may be one reason.
This was a small village of about 16 people that was occupied about 800 years ago. There is a small, but very nice museum and a short walk around the ruins. Most is self explanatory.
The top of this is cut off, but it says "Large Kiva" which is a ceremonial building.
