U.S. Geological Survey Open-File Report 2011-1165

COLOR SHADED-RELIEF IMAGES - 

Color shaded-relief images of the final magnetic data are available
in two formats for the survey area. TIF images are georegistered and
show latitude/longitude tick marks only; they have no extra annotation 
so that they can be co-registered with other overlays.  Page-sized PDF 
images have scales and text for map plot purposes. All images illuminated
from the northeast.
