Helvellyn in the context of "Ambleside"

An arête (/əˈrɛt/ ə-RET; French: [aʁɛt]) is a narrow ridge of rock that separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys. Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. The edge is then sharpened by freeze-thaw weathering, and the slope on either side of the arête steepened through mass wasting events and the erosion of exposed, unstable rock. The word arête is French for "edge" or "ridge"; similar features in the Alps are often described with the German equivalent term Grat.

Where three or more cirques meet, a pyramidal peak is created.

The Lake District, also known as the Lakes or Lakeland, is a mountainous region and national park in Cumbria, North West England. It is famous for its landscape, including its lakes, coast, and mountains, and for its literary associations with Beatrix Potter, John Ruskin, Arthur Ransome, and the Lake Poets.

The Lakeland fells, or mountains, include England's highest: Scafell Pike (978 m; 3,209 ft), Helvellyn (950 m; 3,120 ft) and Skiddaw (931 m; 3,054 ft). The region also contains sixteen major lakes. They include Windermere, which with a length of 11 miles (18 km) and an area of 5.69 square miles (14.73 km) is the longest and largest lake in England, and Wast Water, which at 79 metres (259 ft) is the deepest lake in England.

The Furness Fells (archaic: Fournisfels) are a multitude of hills and mountains in the Furness region of Cumbria, England. Historically part of Lancashire, the Furness Fells or High Furness is the name given to the upland part of Furness, that is, that part of Furness lying north of the line between Ulverston and Ireleth. The hills lie largely within the English Lake District.

Red Tarn is a small lake in the eastern region of the English Lake District, in the county of Cumbria. It is high up on the eastern flank of Helvellyn, beneath Striding Edge and Catstye Cam. Red Tarn was formed when the glacier that carved out the eastern side of Helvellyn had melted. The lake along with three others in Lake District is a habitat for the very rare and endangered Schelly fish. Red Tarn was a dam in the nineteenth century that used boulders that raised the water level some eight or nine feet in order to supply power to the Greenside Mine at Glenridding. Today the tarn is a popular rest stop for hikers and nature goers.

It lies at an altitude of 718 metres (2,356 feet), with a depth of 25 metres (82 feet).
