Gavel Crag forms a striking contrast to Seat Sandal’s otherwise smooth, grassy slopes. Its steep Gavel face has a rugged, volcanic character easily recognised by Coast to Coast walkers. At its foot lies a fan of huge boulders, fractured and scattered from the crag over centuries. The rock is composed of dense andesite lava — evidence of ancient stratovolcanic activity, where cone-shaped volcanoes once emitted slow-moving, viscous flows that cooled into hard, grey lava beds.

From the end of Hause Riggs, Gavel presents a formidable sight — a near-vertical lava core rising abruptly from the eastern flank of Seat Sandal. The crag stands proud and self-contained above a green shoulder of turf, its volcanic origins evident in the columned rock and sheer, ash-grey surfaces that dominate the upper slopes.

Below the Gavel face and Hause Gap, enormous boulders litter the slope. The Coast to Coast path threads its way through them in a twisting course, often hidden in mist or shadow. In low visibility, the route can be hard to follow as the path weaves around these scattered giants of volcanic rock, loosened from the crag above.

Hause Moss occupies a shallow niche hollow beneath the Seat Sandal ridge — a glacial form that began to develop as a corrie but never fully matured. Its apparent depth is deceptive; the ground is thinly earthed, and a clear outflow issues from its lip to form the headwaters of Tongue Gill.

A second view of Hause Moss, lying just east of the Coast to Coast path. Here the main trail merges with an alternative route, both beginning at the foot of Great Tongue. The alternative path follows a deeper course between Great Rigg and Great Tongue before rejoining near the lip of the Moss.

Hause Gap marks the crown of the Coast to Coast path where it crosses the col dividing Seat Sandal from Fairfield. A break in the old boundary wall allows free passage through the gap, leading directly towards the descent to Grisedale Tarn.
