Cavers make extensive use of maps in the pursuit of their speleological
increasingly, digitized versions of the latest maps are available online
or through various commercial software packages. This site assembles online
mapping resources with a particular emphasis on maps
useful to the Virginia Region (VAR) of the National Speleological Society.
Advances in Geographic
Information Systems (GIS) are improving the quality and flexibility of maps all
the time. But these are not the maps used by early cavers to plot the caves
they found. And often, data collected from old maps does not translate
accurately to the modern equivalent. So whether for research purposes, or just
plain old nostalgia, it's worthwhile to hold on to these historic maps and make
available for use. Importantly, the old
geology maps, while 75 years or more older, are often the most detailed record
of cave bearing strata avialable to the casual caver.
