Wasdale is a valley and civil parish in the western part of the Lake District National Park in Cumbria, England. The River Irt flows through the valley to its estuary at Ravenglass. A large part of the main valley floor is occupied by Wastwater, the deepest lake in England (258 feet, 78 mtr).

The pictue shows part of the Wasdale Screes, an area of unstable, loose boulders on the east bank of Wast Water, underneath Illgill Head and Whin Rigg.
