Morecambe Bay

Morecambe Bay is a large estuary in northwest England, just to the south of the Lake District National Park. It is the largest expanse of intertidal mudflats and sand in the United Kingdom, covering a total area of . In 1974, the second largest gas field in the UK was discovered west of Blackpool, with original reserves of over 7 trillion cubic feet (tcf) (200 billion cubic metres). At its peak, 15% of Britain's gas supply came from the bay but production is now in decline. It is also one of the homes of the high brown fritillary butterfly. The rivers Leven, Kent, Keer, Lune and Wyre drain into the Bay, with their various estuaries making a number of peninsulas within the bay. Much of the land around the bay is reclaimed, forming salt marshes used in agriculture. Morecambe Bay is also an important wildlife site, with abundant birdlife and varied marine habitats, and there is a bird observatory at Walney Island. The bay has rich cockle beds, which have been fished by locals for generations. There are seven main islands in the bay, all to the west; Walney, Barrow, Sheep, Piel, Chapel, Foulney and Roa. Walney is substantially larger than the others, with its southern tip marking the north-western corner of the Bay. Sheep, Piel, Chapel and Foulney Islands are tidal and can be walked to at low tide with appropriate care. Local guidance should be sought if walking to Chapel or Piel islands as fast tides and quicksand can be extremely dangerous. Roa Island is linked to the mainland by a causeway, while Barrow Island has been connected to the mainland as part of the docks system at Barrow-in-Furness. The extensive sandflats are the remains of a vast sandur or outwash plain established by meltwaters as the last ice age waned. Sea-level was still some 3m below present day levels at the start of the Holocene some 11,000 years ago. The Greek geographer and astronomer Claudius Ptolemy (died c170 AD) referred in his writings to Morikambe eischusis as a location on Britain's west coast, lying between the Ribble and the Solway.

Morecambe

Morecambe (ˈmɔːrkəm ) is a seaside town and civil parish in the City of Lancaster district in Lancashire, England. It is located in Morecambe Bay on the Irish Sea. The first use of the name was by John Whitaker in his History of Manchester (1771), when he refers to the "æstury of Moricambe". It next appears four years later in Antiquities of Furness, where the bay is described as "the Bay of Morecambe". That name is derived from the Roman name Moriancabris Æsturis shown on maps prepared for them by Claudius Ptolemœus (Ptolemy) from his original Greek maps.
