About this Item

Good. Wear along original fold lines. Verso repairs to fold separations and at fold intersections. Light offsetting. Size 14.5 x 11.75 Inches. A colorful map of the southwestern portion of the Cook Inlet in Alaska produced in 1921 by the U.S. Geological Survey. This period saw a thorough exploration of the Alaskan coast for large-scale oil and gas deposits, which were eventually discovered and exploited in the Cook Inlet Basin several decades later. A Closer Look Coverage includes a portion of the Cook Inlet between Tuxedni Bay and Iliamna Bay, southwest of Anchorage. Color shading is used to distinguish different types of rock, which are explained and organized at left according to geologic era. Elevation is shown by contour lines and marked in feet at peaks. Bays, coastal points, hills, mountains, waterways, and abandoned oil wells are noted. Oil and Gas Production in the Cook Inlet Basin This map was produced during an intermediary period, following the initial oil and gas explorations of the early 20th century, but before a second wave of exploration and limited commercial-scale production began in the mid-20th century. As was the case elsewhere along the coast of Alaska, oil and gas seeps were discovered here in the first decade of the century (especially around Oil Bay here) but were not able to sustain large-scale production. Further explorations were made in the 1950s and 1960s which likewise did not result in hoped-for production, though some geologists believe that the region may still be able to sustain commercial oil and gas production. Further into the Cook Inlet, just north and east of the area shown here, large-scale gas and oil deposits have been exploited since the 1950s. Publication History and Census This map was produced by the U.S. Geological Survey in 1921, borrowing topographical information from the U.S. Coast and Geodetic Survey, to accompany the text 'Preliminary Report on Petroleum in Alaska' by G. C. Martin that appeared in the survey's Bulletin . It is only independently cataloged among the holdings of the University of Calgary and the Sorbonne Université, while the entire report and the full 1921 issue of the Bulletin are more widely distributed.
