Alaskan_fireweed Mammoth tusk and bone inside of the permafrost research tunnel just outside of Fairbanks, Alaska. My son and I got a once in a lifetime opportunity to tour the tunnel. It felt like stepping back in time 30,000+ years seeing mammoth bones and tusks sticking out, the sedges and grasses they ate, and ice wedges. #alaska #permafrost #paleontology #climatechange #mammoths #history
