Q: Are the Chaco Canyon ruins related at all to those at Mesa Verde? EB

A: There are connections between Chaco and Mesa Verde. I’m not an anthropologist or historian. I can say that both were built by the Anasazi, sometimes known as Ancestral Puebloans. I believe the big construction at Mesa Verde started later than the big construction at Chaco, which was occupied for at least hundreds of years and had about a 200 year run of Great Houses (about 950 to 1150AD). People surely moved back and forth between the two locations (among many others throughout the Four Corners). Mesa Verde may have been occupied later than Chaco (into the 1300’s).
