The Kantishna, region as here defined is bordered on the south by the crest of the Alaska Range, on the north by Tanana River, on the east by Nenana River, and on the west by lower Kantishna River and one of its main headward tributaries, McKinley Fork. (See fig. 1.) In a broader sense, the Kantishna region should include the entire Kantishna basin and part of the Nenana basin, but the present paper does not describe the part of the Nenana, basin that lies east of the main river between Broad Pass and the Tanana, the part of the Alaska Range that lies south of a line drawn from the mouth of Hines Creek to the terminus of Muldrow Glacier, and the part of the Kantishna basin that lies west of McKinley Fork and west of the main river below the mouth of McKinley Fork. Furthermore, the lowland of Tanana River north of the outermost range of foothills was visited only along the courses of Kantishna and Nenana, rivers. The area here considered lies between parallels 63° 25' and 65° north latitude and meridians 149° and 151° 10' west longitude. It includes about' 4,500 square miles and comprises a part of the Alaska Range and its foothills and a part of the Tanana lowland.
