The
North Western Fells occupy the area between the rivers Derwent and Cocker, a broadly oval swathe of hilly country, elongated on a north–south axis. Two roads cross from east to west, dividing the fells into three convenient groups. The most northerly sector, rising between
Whinlatter Pass and the Vale of Embleton, includes Broom Fell.
Lord's Seat, is the highest of the fells north of Whinlatter and sends out a long ridge westwards. The ridge begins with a marshy depression before rising to the summit of Broom Fell. It then continues west to the more pronounced saddle of Widow Hause, beyond which is Graystones. Widow Hause, is densely forested on the southern side with the conifers of the Darling How Plantation. To the south of Broom Fell, is the pleasant valley of Aiken Beck, heavily wooded in its lower reaches. This secluded dale lies between the main ridge and
Whinlatter Fell, draining to the west and ultimately reaching the Cocker. Hidden within the Darling How Plantation, is the fine waterfall of Spout Force. On the northern flank of Broom Fell, is Burthwaite Heights (1,043 ft), listed as a separate top in some guidebooks. 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. ==Geology==
