On the northern flank of Broom Fell, is Burthwaite Heights (1,043 ft), listed as a separate top in some guidebooks.Bill Birkett: Complete Lakeland Fells: Collins Willow (1994): This is a small hill beside the vast morass of Wythop. Wythop Moss itself lies to the west and drains (slowly) via Tom Rudd Beck. To the east of Burthwaite Heights, runs the valley of Wythop Beck, emptying rather more effectively between the twin hills of Ling Fell and Sale Fell.
