Long Meg and Her Daughters is a Bronze Age stone circle near Penrith in Cumbria (historically in Cumberland}, North West England. One of around 1,300 stone circles in the British Isles and Brittany, it was constructed as a part of a megalithic tradition that lasted from 3,300 to 900 BCE, during the Late Neolithic and Early Bronze Age. The stone circle is the sixth-largest example known from this part of north-western Europe, being slightly smaller than the rings at Stanton Drew in Somerset, the Ring of Brodgar in Orkney and Newgrange in County Meath.
It primarily consists of 59 stones (of which 27 remain upright) set in an oval shape measuring 340 ft (100 m) on its long axis. There may originally have been as many as 70 stones. Long Meg herself is a 12 ft (3.6 m) high monolith of red sandstone 80 ft (25 m) to the southwest of the circle made by her Daughters. Long Meg is marked with examples of megalithic art including a cup and ring mark, a spiral and rings of concentric circles.
Coniston Water in the English county of Cumbria is the third-largest lake in the Lake District by volume (after Windermere and Ullswater), and the fifth-largest by area. It is five miles long by half a mile wide (8 km by 800 m), has a maximum depth of 184 feet (56 m), and covers an area of 1.89 square miles (4.9 km2). The lake has an elevation of 143 feet (44 m) above sea level. It drains to the sea via the River Crake.
Little Langdale is a valley in the Lake District, England containing Little Langdale Tarn and a hamlet also called Little Langdale. A second tarn, Blea Tarn, is in a hanging valley between Little Langdale and the larger Great Langdale to the north. Little Langdale is flanked on the south and southwest by Wetherlam and Swirl How, and to the north and northwest by Lingmoor Fell and Pike of Blisco. The valley descends to join with Great Langdale above Elter Water.
Crummock Water is a lake in the Lake District in Cumbria, North West England situated between Buttermere to the south and Loweswater to the north. Crummock Water is 2.5 miles long, 0.75 mile wide and 140 feet deep. The River Cocker is considered to start at the north of the lake, before then flowing into Lorton Vale. The hill of Mellbreak runs the full length of the lake on its western side; as Alfred Wainwright described it ‘no pairing of hill and lake in Lakeland have a closer partnership than these’.
“The meaning of ‘Crummock’ seems to be ‘Crooked one’, from British” (Brythonic Celtic) “‘crumbaco’-‘crooked'”. This may refer to the winding course of the River Cocker, which flows out of the lake, or refer to the bending nature of the lake itself. The word “‘water’ is the main Lakeland term for ‘lake'” 
Water from the lake is treated at Cornhow water treatment works, near Loweswater, and is distributed to the towns of Silloth-on-Solway, Maryport, Workington, Whitehaven, and many smaller towns, villages, and hamlets in the surrounding area for drinking and all other uses.
Buttermere is a lake in the English Lake District in North West England. The adjacent village of Buttermere takes its name from the lake. Historically in Cumberland, the lake is now within the county of Cumbria. It is owned by the National Trust, forming part of its Buttermere and Ennerdale property. Wikipedia
