However, it is classed as a Marilyn because of the low elevation of the col connecting it to Haycock, its nearest higher neighbour to the north.

The main watershed runs broadly westwards from Great Gable, dividing the headwaters of Ennerdale and Wasdale.

The River Bleng forms the entire western boundary, beginning on the slopes of Haycock and then flowing out in a huge loop to the south west.

The extremity of the Bleng's circuit, near to Gosforth, is given over to lowland cultivation and although belonging topographically to Seatallan could hardly be termed fellside.

Nether Beck swings away from Seatallan on its southward journey, diverted by the rocky height of Middle Fell.

The tarn, around 30 feet (10 metres) deep, sits in a long narrow bowl, looked down on by a collection of huge boulders.

[2] Seatallan's most prominent feature is Buckbarrow, the 400-foot (120-metre) rampart of crags on the southern edge overlooking lower Greendale and Wast Water.

Above Buckbarrow are the minor tops of Glade How and Cat Bield, leading onto the great south west shoulder.
