Abstract
A cable marker pole system is described for marking the location of buried utility cabling. The cable marker pole system includes a base for embedding in earth or concrete, and a two-part pole assembly that couples with the base. The two-part pole assembly includes a spring coupling the two pole members to allow the pole assembly to flex if struck. A sign is attached to the top of the pole assembly to indicate what is buried.
