Map of permafrost area in Alaska. As indicated in the above map, about 60% of Alaska is underlaid by permanently frozen ground (permafrost). In the most northerly sections, this permafrost often extends to a depth of several hundred feet. In such areas, the usual Stateside methods of maintaining adequate water supplies and waste disposal systems must be extensively modified for effective and economic use.
