Cover Story: Alaska’s Denali National Park and Preserve contains a remarkable geologic record that spans much of the last billion years of Earth’s history. Sedimentary strata of the Cantwell basin represent approximately 10 million years of geologic time in the latest Cretaceous period and have been found to contain one of the most important assemblages of high-latitude dinosaur trackways in North America. In this study, we interpret the evolution of the ancient landscapes that were once home to these species from the sedimentary record. The resulting stratigraphic framework provides context for the emerging paleontological and paleoclimatic datasets from the Cantwell basin, and demonstrates links between basin evolution and regional geologic processes related to the tectonic assembly of southern Alaska. View this paper
