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.

Recent summer warming in northwestern Canada exceeds the Holocene thermal maximum

Depths recorded in GEOCHRON are those from Maher 1982, rather than those reported in Radiocarbon by Bender et al, 1980. (jk/11Aug92)

The structure of Holocene climate change in mid-latitude North America

Lake is located in a pre-glacial gorge of the Wisconsin river cut through the Baraboo Hills, a bedrock high. The valley is dammed at both ends by terminal moraines deposited by the Green Bay lobe, which flowed around the Baraboo Hills. Lake is fed by groundwater. Surrounding vegetation: white-black-bur oak.

ice flow likely to impact the trend in the raw 18O data, but not for the last 5ka; presence of gaps due to melt, identified by sharp variations in th d18O profile; no calibration to temperature published; no study of the seasonality of the proxy
