Topography

As the spur falling north from High Raise gradually narrows, the ground becomes rockier, until a sudden turn toward the east throws up a knuckle of crag. The main face is on the north western flank, cut by a gully, with the lower slabs providing the majority of the rock climbing. Bull crag is also on this flank, a little to the south. From Sergeant's Crag the ridge drops slightly before reaching its terminus at Eagle Crag. Sergeant's Crag has well defined boundaries with Langstrath to the west and the gentler eastern slopes falling to Greenup Gill. These streams converge beneath Eagle Crag to form Stonethwaite Beck. Blea Rock is a conspicuous boulder at the foot of the Langstrath slopes.

Ascents

A stone wall runs along the ridge from Eagle Crag, the accompanying path being the usual route of ascent. This becomes indistinct as the ground broadens toward High Raise. The crag can also be outflanked, climbing without paths from further south along either valley.Mark Richards: ''The Central Fells'': Collins (2003):
