Since the beginning of the retreat of the Laurentide ice sheet that covered much of North America about 18 000 years ago, the ecosystem in the region have being reestablished. It is important to explain pollen record and understand the process to research on relation between air pollen and modern vegetation. In Summer 2003, we do pollen collection in air cross the paleo-Laurentide ice sheet from Seattle to Prudhol Bay and Inuvikand via the highways. The air pollen section with 5563 km in length is composed of 6 parts as follow: (1) From Seattle to Prince George by car via Western Access Route(I-5, BC-99) (950km). (2) From Prince George to Fairbanks by car via Alaska Highway (2772km). (3) From Fairbanks to Wiseman by car via Dalton Highway(303km). (4) From Wiseman to Prudhol Bay by car via Dalton Highway(364km). (5) From Fairbanks to Dawson by car via Richardson highway, Alaska Highway and Top of the world Highway(438km). (6) From Dawson to Inuvik by car via Dempster Highway(736km). This research was supported by funding from the National Natural Science Foundation of China (49971078).
