Geology
Lying on the edge of the Scafell Syncline, the various strata dip to the east. The summit area is formed from a dacite lava flow (Scafell Dacite), directly underlain by the Lingmell Formation. This tuff, lapilli tuff and breccia outcrops a little to the west of the summit. Around Beck Head is evidence of the Crinkle Member, welded rhyolitic tuff and lapilli-tuff with some breccia. A dyke of andesite and hybridised andesite porphyry is responsible for Kern Knotts.
