Description: Technical Report
Summary: The primary purpose of this report is to introduce the reader to the area and to provide him with a guide to the available geologic literature. It is based on a review of the literature and a field reconnaissance of the region. The major landforms of Yukon Flats are flood plains with many meander scars and oxbow lakes, terraces , alluvial fans, and sand dunes. Permafrost is discontinuous but in the poorly drained areas, other than lakes, it occurs to a considerable depth. Glacial drift and moraines, formed during the Pleistocene glaciation of the southern Brooks Range, occur as extensive deposits in the Chandalar River drainage system. Pleistocene valley glaciation is evidenced in the higher mountains of the Hodzana Highland and the Ray Mountains by cirques, hanging valleys, U-shaped valleys, and moraine and outwash deposits. The geologic history of the area is summarized.
