Excerpt from The Bonnifield Region Alaska
Along its northern border the Tanana lowland ends abruptly, giving place to a belt of foothills which stretches southward 15 or 20 miles beyond the flats, where it in turn gives place to the higher mountains. The foothills consist of minor east-west ranges, which lie parallel to the main range and which have for the most part rounded summits and long, smooth, connecting ridges, ranging in elevation from to feet, although here and there hills with somewhat sharper peaks rise to heights of or feet. Be tween the ranges of hills and parallel with them there are in places broad structural valleys which have little relation to the present stream courses, as some of them send their waters into two or three different drainage systems Up to the present time the entire gold production of the region has been from the foothill belt.
