  This folder contains the artwork we used to construct 
  USGS Circular 1259. The files were created with Adobe 
  Creative Suite (*.ai for Illustrator 11 and *.psd for 
  Photoshop 8).  

  We have also provided the captions for the illustrations 
  as a separate text file you can use (2_captions.txt)

  There are files for the cover and inside photographs, 
  the 3-D image on the map supplement (3d_map_supp.ai), 
  and one or more files for each of the 24 figures 
  (c1259_fig_01.* through c1259_fig_24.*).
