It was beneath the Mazama layer that the small microblade core was discovered two years ago. Given the time frame of the Mazama deposit, Burtchard knew they had made a significant find.

“You can get precise time control because you have these volcanic events that you can date,” he said. “They create a timeline from which you can gauge finds.”

A site near Sunrise has deposits from seven major events, including the Osceola lahar about 5,700 years ago.

The North Cascades site also has volcanic layers, ash deposited from eruptions at Mount Baker, Mount St. Helens, Glacier Peak and Mount Mazama.

The site has also produced other ash evidence, coming from cooking pits.

“They’re small and not elaborate, but pretty clearly they were cooking with hot stones. But I don’t know what they were cooking,” Mierendorf said. “That implies more than just traveling through the area.

“These are repeatedly used, including one individual pit used and reused for all 9,600 years. I’ve never seen anything like that in 40 years of professional archaeology.”
