Approaching Elvanfoot on the A702, Glenochar farmhouse is reached. Just to the north, there is Glenochar Bastle and Fermtoun a 17th-century settlement and fortified house. The archaeological dig which revealed this was the winner of the 1997 Pitt Rivers Award for amateur archaeologists. Also, just to the south is the source of the River Clyde which flows north through Lanarkshire and passes through the City of Glasgow. Where the Daer and Potrail Waters confluence, the River Clyde begins. The Daer Water has its head waters near Queensberry and it flows through Daer Reservoir before it meets the Potrail. The head waters of the Potrail are on the north east side of Durisdeer Hill.
