BALTIMORE COUNTY, Md. — State archaeologists and geologists are working together to solve a more than 10,000-year-old mystery at the Piney Grove archaeological site near Reisterstown, building on discoveries first made in May.

State Terrestrial Archaeologist Zachary Singer and State Geologist Rebecca Kavage Adams are tracking the earliest inhabitants of this region — the Clovis people who walked these lands about 13,000 years ago, long before modern humans built the church that now stands nearby.

"Every piece of chalcedony we've found at the site has been worked. Has been flaked,” Zach updates Rebecca. "So this was the hangout and do the work site.” Zach, "Yes, this was the reduction site."
