We dedicate this map to the late Rocky Reifenstuhl, whose countless mapping traverses contributed significantly to our present understanding of North Slope geology. We trust the many stories of his legendary energy will continue to inspire the next generation of Alaska geologists. He is greatly missed. Outcrop stratigraphic work by David LePain and Russ Kirkham contributed to our understanding key stratigraphic relationships in the map area. Valuable discussions with a number of colleagues greatly helped refine our views of the local and regional geology, including David LePain, David Houseknecht, Wesley Wallace, Peter Flaig, Dolores Van der Kolk, Dick Garrard, and Gregory Wilson. University of Alaska Fairbanks students Steve Polkowski, Dolores Van der Kolk, Jake Mongrain, and Peter Flaig all helped with field logistics at some point in the project. We thank Dick Garrard for persistently pushing us forward toward completion of this map, Greg Wilson and Wes Wallace for timely and thoughtful reviews, and Gil Mull for impressing upon us the potential stratigraphic importance of the area and for many insightful conversations and suggestions while planning the mapping project and when considering the final version of the map. Helicopter pilot Tom, Rat, Ratledge expertly transported us throughout the map area and back to camp safely, often pointing out an unnoticed outcrop in the process. Completion of the map was made possible by funding from a variety of sources, including operating and capital improvement project funds from the State of Alaska (Division of Geological & Geophysical Surveys and Division of Oil & Gas), and the STATEMAP program of the National Cooperative Geologic Mapping Program administered by the U.S. Geological Survey (award 08HQAG0051). Fieldwork was also supported by substantial contributions from companies involved in the Alaska oil and gas industry. Recent sponsors (2007 and 2008) included Anadarko Petroleum Corp., BG Alaska, BP, Chevron, ConocoPhillips Alaska Inc., ENI, Petro-Canada, Pioneer Natural Resources, Repsol YPF Exploration and Production Co., Shell International Exploration and Production Co., and Talisman Energy Inc. This map was converted to GeMS then finalized by Alec Wildland and Mike Hendricks. Geologic map conversion to the GeMS standard was funded by the USGS National Cooperative Geologic Mapping Program under StateMap award number G21AC10706, 2021, and the State of Alaska General Fund.

Alaska's North Slope is largely covered by tundra and past exploration has relied heavily on expensive seismic data. The geology exposed along the northern mountain front provides much-needed insight into the evolution of the petroleum system. Many of the geologic relationships delimited by our mapping can be projected into the subsurface and are directly relevant to ongoing exploration. This study presents new findings pertinent to evaluating the resource potential of the gas-prone, south-central Sagavanirktok Quadrangle region. In addition to relevant oil and gas issues, detailed geologic mapping in the Sagavanirktok River investigates several important scientific questions related to deposition of the Brookian Megasequence and evolution of the Colville foreland basin.
