Fells in the context of Tree line

Æsir (Old Norse; singular: áss) or ēse (Old English; singular: ōs) are gods in Germanic paganism. In Old Nordic religion and mythology, the precise meaning of the term "Æsir" is debated, as it can refer either to the gods in general or specifically to one of the main families of gods, in contrast to the Vanir, with whom the Æsir waged war, ultimately leading to a joining of the families. The term can further be applied to local gods that were believed to live in specific features in the landscape – such as fells. The Old English medical text Wið færstice refers to the Ēse, along with elves, as harmful beings that could cause a stabbing pain, although exactly how they were conceived of by the author of the text is unclear.

Áss and its cognate forms feature in many Germanic names, such as Oswald and Ásmundr, and in some place-names in Norway and Sweden. The Æsir further likely give their name to the A-rune, attested in the Elder Futhark, Anglo-Saxon Futhorc and Younger Futhark.

The Lake District, also known as the Lakes or Lakeland, is a mountainous region and national park in Cumbria, North West England. It is famous for its landscape, including its lakes, coast, and mountains, and for its literary associations with Beatrix Potter, John Ruskin, Arthur Ransome, and the Lake Poets.

The Lakeland fells, or mountains, include England's highest: Scafell Pike (978 m; 3,209 ft), Helvellyn (950 m; 3,120 ft) and Skiddaw (931 m; 3,054 ft). The region also contains sixteen major lakes. They include Windermere, which with a length of 11 miles (18 km) and an area of 5.69 square miles (14.73 km) is the longest and largest lake in England, and Wast Water, which at 79 metres (259 ft) is the deepest lake in England.
