Geologically, parts of the Scafell massif are the remnants of a volcano that erupted in the Ordovicianperiod over 400 million years ago. This volcano, geologically described as a caldera and an "inverse stratovolcano", as well as all other volcanoes of the Lake District, are long since extinct.[2]
The volcano is an example of a piecemeal caldera whose collapse, in contrast with a wholesale piston-like subsidence, occurred in a piece-by-piece fashion along faults and whose measurements suggest formation from an eruption of a VEI-7 magnitude, comparable to the Minoan eruption at Santorini in the Greek Aegean in c. 1600 BCE. The Scafell dacite, between Little Narrowcove and Aaron Crags, is a lava dome formed during the last stages of volcanic activity at Scafell massif.[2]
An English Munro (or Furth) is a mountain summit that exceeds 3,000 feet (914.4 m) and has a prominence of more than 30 metres (98 feet). In England there are six peaks that meet that criteria and four of those are part of the Scafell Massif.[a]
(‡) Have the prominence of over 150 metres (492 ft) to qualify as a "Real Munro".
Protected area
The Scafells are situated within a Site of Special Scientific Interest (SSSI)[3][4] designated in 1988 called Scafell Pikes. This protected area includes Seathwaite Fell, Great Slack, Great End, Long Pike, III Crag, Symonds Knott, Slight Side and Scafell Pike and the area of this SSSI is 1102 hectares. This area is protected because of the lichens found in the summit boulder field.
All of the land within Scafell Pikes SSSI is owned by the National Trust.[5]
Accident black spots
The traverse between England's two highest summit's via Mickledore col requires considerable care and caution. The route via Broad Stand is best avoided because it is dangerous.[6] There is a safer but longer route available via Foxes Tarn.
