Field Trip Locations in Google Earth

The New York Geological Association has held Field Conferences since 1925 and produced formal Guidebooks since 1956. Essentially "self-published," these Guidebooks contain many detailed descriptions of rocks and localities which cannot be found in other published sources. In addition to descriptions of rocks, road cuts and regions, these Guidebooks also contain the interpretations of their authors.

Although modified by nature, and often obscured by anthropogenic construction and destruction, most of the rocks are still there. Thanks to Dr. Otto Muller (Alfred University) and his colleagues, this treasure trove of geological information is now easily accessible to interested parties as files that can be uploaded in Google Earth.  Over time, roads have changed, sometimes Interstates and other road construction have removed outcrops, and when it's been possible to decipher those changes, the modifications are noted. However, changes in the original text from the field guides has been avoided, even if current thinking is at odds with the opinions expressed.
