This map is a product of the USGS Digital Geologic Maps of Northern Alaska project, which captures in digital format quadrangles across the entire width of northern Alaska. Sources include geologic maps previously published in hardcopy format and recent updates and revisions based on field mapping by the Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys and Division of Oil and Gas, and the U.S. Geological Survey. Individual quadrangles are digitized at either 1:125,000 or 1:250,000 depending on the resolution of source maps. The project objective is to produce a set of digital geologic maps with uniform stratigraphic nomenclature and structural annotation, and publish those maps electronically. The paper version of this map is available for purchase from the USGS Store.

|View eastward of the Utukok River meanders and the upper part of the Cretaceous Nanushuk Formation on the north flank of the Lookout Ridge syncline. Resistant horizons consist of fine- to medium-grained sandstone and quartz- and chert-pebble conglomerate; they are interbedded with less resistant, silty, carbonaceous shale and coal.
