SANTA FE, N.M. (AP) - Excavations in recent decades in downtown Santa Fe and other parts of the region have taught archaeologists a lot about northern New Mexico's history.

The findings will be the subject of a symposium titled "Beneath the City Different: The Archaeology of Santa Fe" on Saturday afternoon at the New Mexico History Museum. The event has been sold out since early October.

The historic sites archaeologist and historian for the state Historic Preservation Office, Cordelia Thomas Snow, will be among the speakers. She will talk about what recent excavations downtown have revealed about the earliest Spanish settlements.

Snow says archaeologists now know that some of the early colonial buildings were two stories.
