Colorado telephone and telegraph systems, have, in many cases, been underutilized for archaeological site interpretations. These features are often recorded as transmission lines with few attempts at differentiation and little information being gleaned from associated artifacts. This paper provides a brief history of entry of the telephone and telegraph into Colorado and examines three primary pieces of material culture associated with these features: wires, poles, and insulators. These artifacts have the potential to provide limited temporal information, distinguish under what circumstances the line was established and, on a limited basis, differentiate between telegraph and telephone lines.
