and woodland. In the east there are two main chains of hills: one overlooking Windermere, with Latterbarrow (245 m) as its highest point, and the other, which reaches 300 m, overlooking Coniston Water. Between them is flat country and Esthwaite Water. West of Coniston Water is the highest range, the Coniston Fells, with the Coniston Old Man (803 m) as its highest point (and historically the highest point in Lancashire). A lesser range extends from Torver to just north of Dalton, but south of that the landscape is flat; this area is also called Plain Furness. The low rolling hills of Low Furness are formed of glacial deposits, mainly boulder clay, above Triassic sandstone and Carboniferous limestone. There are large deposits of iron ore here, of very pure quality. The human geography of the area is dominated by the town of Barrow-in-Furness. Barrow is located on the tip of the peninsula and Walney Island, and the Borough of Barrow-in-Furness, which includes the small town of Dalton-in-Furness and the town of Millom (the latter of which, although statistically in "Furness" for this purpose, is not actually part of the defined geographic area known as Furness) has a population of 69,100. Barrow, which grew from a small village to a large town during the 19th century, is characterized by a grid pattern of streets of terraced houses, surrounded by more contemporary suburbs. Though the Port of Barrow still contains much industry, there has also been significant redevelopment of former dock areas into retail parks, office blocks and spaces of light industry. The other major town in the area is Ulverston, at the border of Low and High Furness, and the population of Ulverston and its surrounding villages is 17,307. The corridor along the main A590 road between Ulverston and Barrow is relatively densely populated and urban. Despite decline, industry remains a bigger employer in this part of Furness than most of the UK, with BAE Systems, Kimberly-Clark (both Barrow) and GlaxoSmithKline (Ulverston) the largest employers. In Barrow and up the west coast of Furness, the Sellafield Nuclear site is also a significant employer. The rest of Furness is rural, with the mountainous, wooded and lacustrine environments. To the west, the main settlements of Kirkby-in-Furness and Broughton-in-Furness are dominated by farming and commuting. The Lake District National Park covers most of High Furness, with Coniston and Hawkshead the main centres for tourism, while
