5 10 15 20	Around the year 1500, hunting people occupied the entire northern third of North  America. They lived well from the animals with whom they shared these lands. Hunters  of sea mammals had colonized the Arctic coasts of Canada and Greenland between  Line four and five thousand years before. Land-hunting people had lived throughout much of the northern interior for at least 12,000 years.      Northern North America is part of a larger circumpolar ecological domain that  continues across the narrow Bering Strait into Siberia and northern Europe. The overall  circumpolar environment in the 1500's was not very different from the environment of  the present. This vast landmass had a continental climate and was dominated by cold arctic air throughout a long winter and spring season. Summer temperature ranged  from near freezing to the mid-20's Celsius, while winter temperature were often as  low as 40 degrees below zero Celsius.      Geographers divide the overall circumpolar domain into two zones, the Arctic and,  below it, the Subarctic. They refer to the landforms of these areas as tundra and taiga, respectively.      Temperatures in the northern lands were below freezing for eight or nine months of  the year. Subsurface soil in the Arctic's tundra remained permanently frozen. Even  when summer temperatures were above freezing and the top inches of earth became  saturated with water, the soil below remained frozen into a permafrost, as hard as rock. When water flowed upon the surface of permanently frozen tundra, it made overland  travel extremely difficult. Summer travel in the boggy lands, or muskeg country, of the  Subarctic's taiga was also slow and arduous. Tracking animals was more difficult than  it was during the winter when the swampy ground was frozen solid and covered with  snow. In both tundra and taiga, hordes of mosquitoes and biting flies bred in the standing pools of water. Clothing lost its thermal efficiency when it became damp.  Northern people looked forward to the turn of the season to bring the easier traveling  conditions associated with cold weather. In the Arctic, they could haul food and  supplies by dogsled while in the Subarctic, people could travel quickly and efficiently  by snowshoes and toboggan.
