The Geum River and its tributaries were a means of cultural contact from prehistoric times (see Mumun Pottery Period) and into the Three Kingdoms of Korea through their ancient function as a transportation route that begins on the west coast and penetrates deep in the interior of the Peninsula.
The river's Korean name ("Silk River") is a homonym of the word for "diamond" (금강; 金剛) and should not be confused with Kŭmgang Mountain (금강산; 金剛山; "Diamond Mountain") in North Korea.
