The Highpointers Club doesn’t have a definitive online guide. There are plenty of books available at the Highpointers Merc.
The original page came from americasroof.com.
The best sources now for current information are two interactive sites: summitpost.org and wikipedia.org. Of these two summitpost is the definitive choice among climbers. However wikipedia lets you edit the description directly. This produces some amazing information on the mountains. The wikipedia articles are relatively young so your help is definitely wanted there.
The Highpointers Club maintains that the USGS is the official source for the Club.

For an incredible interactive map, see’s David Kelly’s ARCSOFT topo map that lets you zoom in very fast to the smallest map available! In 2014 David also created an awesome ARCSOFT topo map of county highpoints.
