Geology Along Going-to-the-Sun Road, Glacier National Park, Montana
Omer B. Raup, Robert L. Earhart, James W. Whipple, Paul E. Carrara 1983 Glacier Natural History Association
This guide describes many of the major geologic features of the Park. It is directed toward the Park visitor with little to no background in geology. The guide begins with a short introduction to the science of geology and the geologic time scale, followed by a simplified geologic cross section through the Park from SW to NE. The bulk of the field guide is a 21-stop road log, keyed to numbered octagonal signs along the road. A glossary of geologic terms and an appendix is included which contains a brief geologic history of Glacier National Park, explanations of rock colors and fossil algae (stromatolites), and descriptions of the Proterozoic rock formations that can be seen along the Going-to-the-Sun Road. An extremely useful resource included at the back of the book is a fold-out geologic map, plotted on an oblique shaded-relief diagram, that depicts the landscape and the distribution of rock formations and faults in the vicinity of Going-to-the-Sun Road.
