Editing Lake District (section)

===Coast===
The Lake District extends to the coast of the Irish Sea from [[Drigg]] in the north to [[Silecroft]] in the south, encompassing the [[estuary|estuaries]] of the [[River Esk (Ravenglass)|Esk]] and its tributaries, the [[River Irt|Irt]] and the [[River Mite|Mite]]. The intertidal zone of the combined estuaries includes sand, shingle and mudflats, and [[saltmarsh]]. The dune systems on either side of the estuary are protected as nature reserves; Drigg Dunes and Gullery<ref>{{Cite web|url=http://cwr.defra.gov.uk/default.aspx?Site=6167|title=Defra, UK - Rural Affairs|website=cwr.defra.gov.uk|access-date=19 August 2019|archive-date=29 July 2019|archive-url=https://web.archive.org/web/20190729233429/http://cwr.defra.gov.uk/default.aspx?Site=6167|url-status=live}}</ref> to the north and Eskmeals Dunes<ref>{{Cite web|url=https://www.cumbriawildlifetrust.org.uk/nature-reserves/eskmeals-dunes|title=Eskmeals Dunes &#124; Cumbria Wildlife Trust|website=www.cumbriawildlifetrust.org.uk|access-date=19 August 2019|archive-date=14 July 2019|archive-url=https://web.archive.org/web/20190714093344/https://www.cumbriawildlifetrust.org.uk/nature-reserves/eskmeals-dunes|url-status=live}}</ref> to the south. South of the estuary, the coast is formed in low cliffs of glacial [[till]], sands, and gravels.<ref>{{Cite web|title=GeoIndex - British Geological Survey|url=https://mapapps2.bgs.ac.uk/geoindex/home.html|access-date=7 February 2023|website=mapapps2.bgs.ac.uk}}</ref>

The district also extends to the tidal waters of [[Morecambe Bay]] and several of its estuaries alongside the [[Furness Peninsula|Furness]] and [[Cartmel Peninsula]]s, designated on M6 motorway signposts as the "Lake District Peninsulas", and the southern portions of which lie outside the park. These are the [[Duddon Estuary]], the [[River Leven, Cumbria|Leven Estuary]], and the western banks and tidal flats of the [[River Kent#Lower river|Kent Estuary]]. These areas are each characterised by sand and mudflats of scenic and wildlife interest. The coast is backed by extensive flats of raised marine deposits left when the relative sea level was higher.
