Book Description

Excerpt from The Fairbanks and Rampart Quadrangles, Yukon-Tanana Region, Alaska The main features of the surface can be learned from the topo graphic maps and need no further comment in the text. The relief, the drainage, the relations of the various drainage systems to each other, the grades of the streams, the comparative elevations and grades of different valleys are all brought out on the maps, and many of their economic relations are thus made clear to those who read the maps with care. If, for example, the digging of a ditch or the con struction of roads or railways is under consideration, the most feasi ble routes can be approximately determined by a study of the maps.
