 The northern slopes fall gently toward Warnscale, the workings of Dubs Quarry lying at the foot of the slope.Brandreth is thus the only fell to feed Ennerdale Water, Derwentwater and Buttermere.The ridge connecting to Green Gable narrows to Gillercomb Head, complete with a number of small tarns, following the line of the ruined Ennerdale boundary fence.
