Carnforth
Carnforth is a small town as well as civil church near Lancaster in the north of Lancashire, England, positioned at the north east end of Morecambe Bay. The parish of Carnforth had a population of 5,350 recorded in the 2001 census, and also types part of the City of Lancaster. The 2011 Census determined a population of 5,560. Because of the closeness of the coastline as well as capitals, Carnforth is a popular base for pedestrians and bicyclists discovering the location. The River Keer, the West Coast Main Line (WCML), the A6 and also the Lancaster Canal travel through the town. The M6 motorway passes just to the eastern, connected to Carnforth by the A601(M). The name "Carnforth" is believed to originate from its old function as a ford of the River Keer on which it is positioned. In time the descriptive name "Keer-ford" might have morphed into the modern-day "Carnforth". An alternate explanation is that the name derives from 'Chreneforde' and also is Anglo-Saxon in beginning, as pointed out in the Victoria County Background of Lancashire.
