The mouth is the confluence with the Conestoga River at an elevation of 278 feet (85 m) at Talmage in West Earl Township, Lancaster County.
The name of the creek comes from the Lenape, meaning "snake dens". It comes from the Lenape word Gookcalicunk (pronounced "Gook Cal-eek Unk) which means “Snake Sleep Place” in English. The Lenape considered modern East Cocalico, West Cocalico, Clay, Warwick, Elizabeth, and Penn townships, Lancaster County, Mill Creek Township, Lebanon County, and the Middle Creek Wildlife Management Area as part of Gookcalicunk.
