This is a composite record representing two permafrost cores from the DHP174 peatland (Dempster Highway peatland, near the 174 km marker), and covering the last 13.6 ka. This record is comparable in ways to an ice core, but different in that it accumulates below the surface and traps primarily summer precipitation. Likewise, the temperature reconstruction is linked to the summer season.
