Geology of Harpers Ferry

If you would like to know more on the geology of Harpers Ferry, check out this
USGS Map from 2000. or an older version at http://pubs.usgs.gov/bul/b2123/pl1-150dpi.pdf from 1996.

The Shenandoah Boulders and Giggling Boulders are apparently a metasiltstone (metamorphosized siltstone) and most of the other rock you climb on is quartzite (metamorphosized sandstone). There are multiple kinds of faults, and intrusive rocks in the form of dikes. This area has some pretty cool geology to check out.
