Post-Glacial Vegetation History of the Ittlemit Lake Basin, Southwest Yukon Territory
The pollen record of a 240 cm peat profile in the Ittlemit Lake area in southwest Yukon Territory presents a vegetation development history of the last 9000 radiocarbon years. Spruce migrated into the area at least 9000 radiocarbon years ago. From 9000 yr BP to approximately 5000 yr BP the area supp...
