The snow covered fell in this photograph is known as High Street.
High Street is a fell in the English Lake District. At 828 metres (2,718 ft), its summit is the highest point in the far eastern part of the national park. The fell is named after the Roman road which ran over the summit.
If you look closely you may be able to see a group of walkers on the left of ridge, they're just a series of dots.
I took this photo in February while walking there.
