Tennessee Power Co. built the 12.1-mile long Great Falls-Spencer 46-kv Transmission Line in 1913 as part of a 151-mile line connecting the Ocoee No. 1 Hydroelectric Plant to Nashville. H.M. Byllesby & Co. designed the towers and the Nashville Bridge Co. assembled them. The 44-foot tall, 2,215 lb galvanized steel towers were designed to withstand severe weather conditions. Vanderbilt University football players helped clear trees and brush from the right-of-way. This line was tied into Great Falls Hydroelectric Station after completion of the powerhouse. The Tennessee Electric Power Co. bought the Great Falls-Spencer transmission line in 1922. The Tennessee Valley Authority acquired it in 1939. The line remained in continuous service for 103 years. When Caney Fork Electrical Cooperation upgraded their Spencer, Tennessee substation, TVA replaced the old line with a 161 kV line supported on steel poles.

Example

For example, one family's tree showed the Articles of Confederation marker in Pennsylvania standing under a mile from where William Gabby lived in the 1760s.

What that marker records spans 1777 to 1789, overlapping William Gabby's years there.
