Based on a talk given by Rick Saltus, this USGS open-file report uses a slideshow format to present work completed and methods used to "edit, document, distribute, and interpret about a million line-kilometers of aeromagnetic data in Alaska." Intermingled with excellent thumbnail graphics, the text describes and explains the accompanying images. Section titles include an Introduction to Magnetic Data, Alaska Aeromagnetic History, Making a Magnetic Quilt, Zooming out: Crustal-scale Interpretation, Zooming in: Interior Alaska Geophysical Framework, Looking Ahead: Live Databases and 3D Interpretive Models, and References: for Further Reading.
