Discussions with Ken Helmold, Richard Stanley, Bob Swenson, Kate Bull, Ron Cole, Ken Ridgway, Emily Finzel, Dick Reger, Jeff Trop, Jamey Jones, Erin Todd, Rick Levinson, Jake Mongrain, Richard Lease, Peter Haeussler, Richard Koehler, and Paul Betka improved our understanding of southern Alaska geology and refined our interpretations. Erin Todd kindly commented on our interpretation and discussion of the igneous geochemistry. David Doherty introduced us to the area prior to commencing field studies and provided valuable insights. Mark Schmitz kindly provided his spreadsheet for calculating maximum depositional dates. Samples were collected by Larry Freeman, David LePain, Bob Gillis, Brent Elliott, Marwan Wartes, Trystan Herriott, David Mauel, Emily Finzel, Jake Mongrain, and Ken Ridgway. University of Alaska, Fairbanks undergraduate interns Keane Richards and Kandace Krecji helped with sample logistics and data entry and provided assistance in the field. Pathfinder Aviation and pilots Merlin (Spanky) Handley, Marty Staufer, Chuck Redd, Ray Hodges, and Hightower Paxton, along with Tom (Rat) Ratledge of Yukon Helicopters, safely and skillfully transported us to every corner and creek in the field area. Jack Barber at Alaska Air Taxi flew personnel and gear to our field base camp. Bob Freeman at Three-Mile Camp kept us well fed and dry during the record-breaking 30 consecutive days of rain in the summer of 2010. Land access was kindly permitted by Cook Inlet Region, Inc. (CIRI) and Tyonek Native Corporation. This project was funded by State of Alaska Capital Improvement Project funds and the U.S. Geological Survey's National Cooperative Geologic Mapping Program STATEMAP component (award numbers G09AC00177 and G10AC00321). Reviews by Emily Finzel and James V. Jones III helped to substantially focus the manuscript and improve its contents.

The Cook Inlet basin analysis program aims to produce more accurate and modern geologic maps and supporting datasets to facilitate developing a better understanding of the Cook Inlet petroleum system's near-margin stratigraphic and structural components.
