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.

Sergeant's Crag has well defined boundaries with Langstrath to the west and the gentler eastern slopes falling to Greenup Gill.

[1] A stone wall runs along the ridge from Eagle Crag, the accompanying path being the usual route of ascent.

High Raise and Ullscarf obstruct the eastward view, but there is a fine display of the North Western and Northern Fells.
