Geology of the Mount LeConte 7.5-Minute Quadrangle, Great Smoky Mountains National Park, Tennessee and North Carolina


This report was prepared at the request of the Great Smoky Mountains National Park as part of a U.S. Geological Survey-National Park Service cooperative agreement.Geologic map data from this report and from other quadrangles will be used in the preparation of a new 1:100,000 scale bedrock and surficial geologic map of the Great Smoky Mountains National Park.

This geologic map was prepared first by compiling existing geologic data from Hadley and Goldsmith (1963).Contacts and selected structural data were plotted on a modern 1:24,000-scale topographic base.  This data was then field checked.  About 500 new observations were added to the map using data from outcrops along roads and trails throughout the quadrangle.  Additionally, off-trail traverses were made in selected areas to delineate the extent and nature of the surficial deposits.Modern debris flows in the Mount Le Conte area were compiled from Bogucki (1970).Debris flows, post-dating the study of Bogucki (1970) were mapped from aerial photographs taken in 1995.  Field checking of many of the modern debris flows was done during the course of mapping.
