Blea Rigg is a broad plateau, around a mile wide and two miles long, climbing roughly east to west. It connects via a narrower section between Stickle and Codale Tarns to Sergeant Man and ultimately High Raise in the west. Stickle Tarn is the larger of the two waterbodies, a 50 ft deep corrie tarn with the level increased by a stone faced dam. It is used to supply water to the residents of Great Langdale. Codale Tarn is a shallow pool set amid rough ground, a little to the north east.
