The southern boundary is formed by Scale Beck and its tributary Black Beck. Mellbreak has a third much lower top overlooking this steep sided valley, Scale Kott (1,109 ft). At the head of Black Beck is the connection to Starling Dodd, running south west from Scale Knott. This could hardly be considered a ridge in walking terms, since it begins at the foot of an 800 ft scree slope on the northern flank of Starling Dodd.
