Project (.axl) Files

Do you wish to explore further the abilities of using maps to illustrate Colorado's historical geography?  You can use ArcExplorer to make your own maps or use the file downloads below to copy the .axl (project) files to the same directory as the data and alter them as you please.  REMEMBER: the .axl files must be copied to INSIDE the ColoradoData directory (and all of its data) that came with the CD.  You will need WinZip (www.winzip.com) or other decompression software to unzip the files below.

Click HERE for a zipped file of ALL current .axl project files.  Unzip these INSIDE the ColoradoData directory.  After opening the files in ArcExplorer you may resave them to any location.

Student Worksheets and Conceptual Overview documents 

The documents below are provided in Microsoft Word format.  Documentation and directions have been slightly altered from the internet mapping versions of the conceptual overviews and worksheets to be used with ArcExplorer 9.0.  If you are using the ArcExplorer Education Edition the directions will result in some discrepancies. You should however, with relatively minor changes, be able to adapt them for use with ArcExplorer for Education Edition.  Click below do download a zipped file of each set of activities:
