  2. 2. Introduction <ul><li>Easily the largest North American region </li></ul><ul><li>Extends from northern Alaska and Canada as for south as the northern Great Lakes </li></ul><ul><li>Regional criteria </li></ul><ul><ul><li>Inhospitable nature of the physical environment </li></ul></ul><ul><ul><li>Sparse population </li></ul></ul>

  4. 4. Climate <ul><li>Dominant feature: COLD </li></ul><ul><ul><li>Average January temperatures -7° C (27  F) along the southern Great Lakes to -40°C (-39  F) in parts of Arctic Canada </li></ul></ul><ul><ul><li>Temperatures as low as -60°C (-76°F) possible </li></ul></ul><ul><li>Long winters, short frost-free period </li></ul><ul><ul><li>135 days at southern margins </li></ul></ul><ul><ul><li>14 days along parts of Arctic Ocean </li></ul></ul><ul><ul><li>Less than 90 days over most of region </li></ul></ul><ul><ul><li>Too short for agriculture </li></ul></ul>
