The historic finds are believed to include a rare shallow basin pit house which was a form of shelter from the archaic period. Final testing is being conducted on the items.
William Whitehead, the lead archaeologist with SWCA Environmental Consultants, says scientist hope to use the items to analyze human behavior including diet and their environment.
After being examined the artifacts will be turned over to the Museum of Indian Arts and Culture in Santa Fe to be curated.
