[Jamestown1630]

I thought 'Snapfinger' was such an odd name, I had to look it up:

SNAPFINGER CREEK, DeKalb County. An undocumented story relates that when DeKalb County was being surveyed, one of the surveyors Spaniard Mountain 208 Georgia Place-Names tripped at the edge of an unnamed creek and broke his finger. Because he "snapped" his finger, the creek became known as Snapfinger Creek. Brinkley declares the name of the stream was adopted because it is a "branch" or "finger" of Snapping Shoals Creek. Union general, George Stoneman was involved in a skirmish by this stream July 27, 1864. The stream name has also been applied to the community of SNAPFINGER and also to SNAPFINGERROAD in the South Decatur area.

The creek is also a regular recipient of sewage overflow from the pitiful DeKalb County sewage system.
