Colesdalen
Colesdalen is a valley in Nordenskiöld Land at Spitsbergen, Svalbard. The valley debouches into the bay Colesbukta, at the southern side of Isfjorden.
Colesdalen is located north of the Nordenskiöld Land [National Park], but not included in the park, due to mining interests.
The Coleselva River flows through the valley.
