Harter Fell

Harter Fell is a fell in the western part of the English Lake District, located between the Eskdale and Duddon valleys. Its height is 653 metres. The fell offers excellent insights into the structure and composition of the Birker Fell formation of the Ordovician Borrowdale Volcanic Group. The summit area bears three rocky tors, the middle one of which is the highest, with an Ordnance Survey triangulation column standing on the western outcrop. From its summit, each of the ring of fells known as the Eskdale Horseshoe can be clearly seen. The fell is dominantly composed of composite andesite lava flows, with autobrecciated upper surfaces developed in some locations. There are several walking routes to the summit, including a 9.5-km loop trail that is generally considered challenging and offers beautiful sweeping views
