Research is being conducted on the geological history of Alaska's Brooks Range, including its tectonic history and the process of westward subduction. Studies are examining the region's crustal thickness, plate tectonics, and erosion, with some focusing on specific time periods, such as the Late Cretaceous-Cenozoic era. The findings have implications for understanding the region's crustal modification and accretion of tectonic units, although the scope of the research appears to extend beyond the Brooks Range to include western Canada.
