The hydrographic data are available at two scales based on the 1:50,000 and 1:250,000-scale topographic source maps that were generated in 1990 and 1993, respectively. Morphological and edaphological data were digitized from a 1:500,000 map published in 1983. There are 3 compressed (*.zip) data files with this data set.}, publisher={ORNL Distributed Active Archive Center}, author={Walsh, S.J. and Bilsborrow, R.E. and Frizzelle, B.G.}, year={2012}, language={en}, }
