List Description

Note that this list is not authoritative and it is present here mainly so climbers can log their ascents. If you are serious about county highpointing in Illinois, then you should visit the County Highpointing Web Site, join the Yahoo County Highpointing Group, and refer to Andy Martin's book for the definitive listing of all the points.


Sources that were used to help me compile this list include:

  • Book County High Points by Andy Martin; list compiled 1997 by Andy Martin, David Olson, and John Mitchler.
  • Some latitude-longitude values for peaks and sub-areas provided by John Hasch via the web site, and manually verified. I manually located the 62 points for Calhoun County.
