• Mount Rainier glacier free with modern flora to 5,500 feet for ca. 10,000 years
• Mid to late Holocene replacement of open parkland habitats by more nearly closed forest communities
• Earliest human use of upper elevation landscapes about 9,000 to 9,500 years ago, consistent with early Holocene land-use onset
• Increased fire frequency after 3,500 years ago; best explained by human ignition –arguably to retard forest cover in favor of more productive parklands
