During the formative years of northern pedologic studies in Alaska, the term Arctic generally was reserved for the Brooks Range and land to the north. Some investigators, however, extended the definition to include some of the treeless sectors of western and central Alaska. Delineations generally were based on a combination of vegetation and temperature, plus the presence of permafrost. Permafrost is present in various patterns in virtually all of Alaska, except some land bordering the Gulf of Alaska (Brown et al., 1997). One rightfully could include as Arctic nearly all of Alaska, but, in this chapter, discussions are almost exclusively of the Brooks Range, Arctic Foothills, and Arctic Coastal Plain.
