Topography

North of Sadgill, the valley of Longsleddale narrows considerably with walls of crag on either side, the most prominent feature on the eastern side being Buckbarrow Crag. Above this and set back out of sight from the valley is a second tier of rock, Tarn Crag. Being near to the summit, this has given its name to the fell as a whole. Tarn Crag is generally held to mark the transition from Lakeland to Pennine country. Away from the fierce western flank, the fell falls in long easy slopes of coarse grass and heather, with little outcropped rock in evidence.

The northern boundary of the fell is formed by the walkers pass from Longsleddale to Mosedale, which crosses a marshy depression at 1,555 ft. Mosedale beck has its source here, beginning its long journey north east to Swindale. Beyond the depression the ground rises again northward up Selside Brow to Branstree

. This holds the diminutive Greycrag Tarn, actually a series of small pools on the bed of a larger body of water. The tarn empties into Longsleddale via Galeforth Gill, but issuing eastwards from the same marsh is Little Mosedale Beck.

Mosedale and Little Mosedale Becks meet a mile to the north east of Tarn Crag, defining its eastern boundaries. A descending ridge makes for the confluence over Brunt Tongue, where a small patch of conifer plantation makes this point distinguishable from miles around. There are few other trees in this moorland landscape.

Haweswater Aqueduct

A fence crosses the fell just east of the summit and this runs along the Sleddale Fells from Selside Pike

 in the north to Grey Crag and its satellite, Harrop Pike in the south. This boundary provides an aid to route finding in poor conditions. Another man made feature near to the summit is the remains of a surveying pillar. This unusual stone and concrete construction is cleft at the top to provide a sight line and was originally surrounded by a wooden frame, now decayed. This is one of four such pillars built during the construction of the Haweswater

. The tunnel, some 1,300 ft below the summit, required 250 tons of gelignite for blasting, and when constructed in the 1930s was the longest such pipeline in Britain. It emerges into Longsleddale below Great Howe, where the spoil can still be seen.

View

The view from the grassy summit is disappointing in terms of fells, but a wide vista from Morecambe Bay to the Pennines opens up in other directions. A portion of Windermere is visible to the south west.

Ascents

Tarn Crag can be climbed from Longsleddale via Great Howe or from a point north of Buckbarrow Crag. Longer approaches from Swindale or Shap via Brunt Tongue are also possible.
