Hozomeen Chert

Hozomeen chert is a locally abundant and distinctive tool stone found exclusively in the northern Cascade range of Washington and British Columbia. Over the last two decades, archeologist Bob Mierendorf has studied quarries near today’s Ross Lake reservoir that reveal a 10,000 year long record of indigenous involvement with this rugged, high-mountain landscape.
