Comment (Location): Original county name was Lewis and Clark. However lat/long plots just inside adjacent Jefferson county. Possible duplicate record 10197130 has identical site name, commods, etc but different reference. Duplicate record 10197130 lat/long plots 600 m south of the problem record, well inside Jefferson county. Jefferson was added to the county names and promoted to first place in this problem record, but this record may continue to cause problems because the lat/long is so close to the county line. In Google Earth, the county line changes sides as you zoom in because of an insufficient number of vertices in the county line.
