It also holds the longest and deepest lakes in England. "Cumbrian Mountains" is the name also used for the Lake District Mountains. The Lake District's four highest mountains each surpass 3000ft (914m).
Some diverse forms of wildlife can be found in the Lake District, with some being exclusive in England. It provides a home for the red squirrel and colonies of sundew and butterworth, two of the few carnivorous plants native to Britain. The Lake District is the only location in England to have two nesting Golden Eagles. The lakes of the Lake District take care of three endangered and rare groups of fish: the Arctic charr, the vendace and the schelly.
Farming, and in particular sheep farming, has been the main industry in the Lake District since Roman times. The tough Swaledale, Rough Fell and Herdwick sheep are all common breeds related with the Lake District.
The wide range of rock types and expanse in the area mean that, quarrying and mining have long been significant activities in the Lake District economy. In Neolithic times, the Lake District was a major source of stone axes, with specimens being found throughout Britain. The Langdale Pikes on the slopes holds the main site and, is at times described as a "stone axe factory" of the Langdale axe industry. Early stone circles existing in Britain are connected with the industry.
Mining, specifically of slate, baryte, lead, slate and copper, was traditionally a major Lakeland industry, mostly from the 16th century to the 19th century. Coppiced woodland was used extensively to provide charcoal for smelting. Some mining still takes place today; for instance, slate mining continues at the Honister Mines, at the top of Honister Pass. The locally mined graphite led to the development of the pencil industry, especially around Keswick.
In the middle of the 19th century, half the world textile industry's bobbin supply came from the Lake District area. The park's main industry has now developed into tourism, with approximately 12 million visitors per year, largely from the larger UK settlements, Japan, China, Germany, the US and Spain. Cumbria's most favoured tourist attraction is the Windermere Lake Steamers. Tourists are greatly attracted to the plenitude of writers and artists in the Lake District that has supplied summer theatre performances in the old Blue Box of Century Theatre for many years. The theatre heritage is carried on by venues such as Theatre by the Lake in Keswick with its Summer Season of six plays in repertoire, Christmas and Easter productions and the multitude of mountaineering, film, literature, creative arts and jazz festivals.
Residing at Hill Top Farm over the early 20th century, Beatrix Potter, the children's writer was, using the region of the Lake District in most of her notorious Peter Rabbit books. The Lake District has been the setting for crime novels by Val McDermid, Reginald Hill and Martin Edwards. Further use of the region's settings is used in the 1926 novella The Torrents of Spring by Ernest Hemmingway and features greatly in Ian McEwan's Amsterdam, winning the Booker Prize in 1998.
