Dettah is located on the Northern shore of Great Slave Lake, just outside of Yellowknife. It is a 6.5 km drive by ice road in winter and a 27 km drive on an all-season road.
In 1959, there were about 15 houses in Dettah. A fire burned out of control, reducing the entire point to ashes, and requiring the residents of Dettah to start anew.
The Dettah area has been used as a summer time gathering site for generations, eventually growing into one of the two Yellowknives Dene Communities
