Yukon-Tanana Upland airborne magnetic geophysical data merge, version 2025 (ver. 2.0, March 2026)

The Yukon-Tanana Upland - Kuskokwim airborne magnetic geophysical data merge provides a merged raster grid of magnetic data for the Yukon-Tanana Upland (YTU) into the Kuskokwim Mountains, Alaska. This dataset provides a regionally consistent magnetic grid while retaining as much detail as possible of the originating data by leveling all the region's magnetic grids to one another. This 100-m cell-size magnetic grid will assist in evaluating the region's geologic structure, geologic processes, tectonic evolution, and mineral resource potential. The grid was compiled from previous studies published by the Alaska Division of Geological & Geophysical Surveys (DGGS).
