Greenside Mine (sometimes referred to as Greenside Lead Mine) was a successful lead mine in the Lake District of England. Between 1825 and 1961 the mine produced 156,000 long tons (159,000 tonnes) of lead and 1,600,000 ounces (45 tonnes) of silver, from around 2 million tons of ore. During the 1940s it was the largest producer of lead ore in the UK. Unusually for a 19th-century metalliferous mine in Britain there are very full records of its activities, dating back to 1825. The mine probably opened during the second half of the 1700s but had closed by 1819. In 1825 the Greenside Mining Company was formed and reopened the mine. They made good profits until 1880, when the price of lead fell. Many other lead mines closed at that time, but the company reduced its costs and continued to work Greenside until 1935. Electricity was introduced to the mine in the 1890s, and it became the first metalliferous mine in Britain to use electric winding engines and an electric locomotive. In 1936 the Basinghall Mining Syndicate Ltd. acquired the mine and turned it into a high volume lead producer. The mine closed in 1962 after lead reserves had been exhausted. Just before it closed the mine was used by the Atomic Weapons Research Establishment (AWRE) to conduct an experiment in detecting seismic signals from underground explosions. Fifteen years after the mine closed mine explorers began to visit the upper levels. They cleared the entrances and several roof falls, and today they are able to pass through the mine using an old escape route. All the ore produced by the mine came from the Greenside Vein, a mineral vein which filled a geological fault running in a north–south direction through the east ridge of Green Side, a mountain in the Helvellyn range. Mining activities traced this fault for a length of 3,900 feet (1,200 m) and to a depth of 2,900 feet (880 m). Four areas of the vein, known as ore shoots, contained galena, an ore of lead which also contained small amounts of silver. At first the ore was mined simply by driving adits into the mountain-side. To access ore at greater depths, two longer levels were driven from lower down but further away, and then a series of shafts were sunk within the mine. The lowest point in the mine was roughly 100 m below sea level, where the surrounding andesite rock rested upon underlying shales in which the fault had not been mineralised. Two processing mills were built to crush the ore and separate out the galena from it, and the mine had its own smelt mill between 1828 and 1917, but after that it was more economical to sell concentrated galena to a commercial smelter. Machinery in the mine and the mills was powered by the plentiful water supplies in the area, used to drive water wheels and power hydraulic engines, and, after 1890, to generate hydroelectricity. Dozens of carts transported supplies to the mine's remote location, and carried the lead out. In the early 1900s the mine set up its own road haulage business using two steam wagons. The men who worked at the mine during the 19th century travelled from a wide area, and many stayed each week in the lodging shops (bunkhouses) built at the mine. In time the company built dozens of houses in Glenridding and at Seldom Seen in Glencoynedale where a school was also built. Mining work was carried out by groups of men who took contracts to do specific jobs, and were paid by their results. Those who worked transporting ore out of the mine or processing the ore were paid at weekly rates. The closure of the mine resulted in a major loss of employment in the area.

Birkhouse Moor is a fell in the English Lake District, an outlier of the Helvellyn range in the Eastern Fells. It is properly an eastern ridge of Helvellyn, but was treated as a separate fell by Alfred Wainwright in his Pictorial Guide to the Lakeland Fells. That convention is followed here.

Glenridding Dodd (the rounded hill above Glenridding) is a small fell in the English Lake District, at the end of a ridge descending from the Helvellyn range in the Eastern Fells. It stands above the village of Glenridding and on the western shore of Ullswater. Although small and not of great elevation, its top is a fine viewpoint for Ullswater and for the fells clustered round the valleys above Patterdale.

Glenridding is a village at the southern end of Ullswater, in the English Lake District. The village is popular with mountain walkers who can scale England's third-highest mountain, Helvellyn, and many other challenging peaks from there.

Glenridding House is a Regency era building in Glenridding on Ullswater, constructed between 1807 and 1814. It was a private summer villa until about 1860 and then became a guest house. It has recently been fully restored and is now a country house bed and breakfast and wedding venue. The building is recorded in the National Heritage List for England as a designated Grade II listed building.

Raise is a fell in the English Lake District. It stands on the main spine of the Helvellyn range in the Eastern Fells, between Thirlmere and Ullswater.

Catstye Cam is a fell in the English Lake District. It is an outlier of Helvellyn in the Eastern Fells.

Stybarrow Dodd (the hill of the steep path) is a mountain or fell in the English Lake District. It stands immediately north of Sticks Pass on the main ridge of the Helvellyn range in the Eastern Fells, which is situated between the lakes of Thirlmere and the Ullswater. The summit of Stybarrow Dodd is a smooth, rounded, grassy dome, like those of its two northern neighbours, Watson's Dodd and Great Dodd. Together, these three rather similar fells are sometimes called ‘The Three Dodds’. All three are covered by the same sheet of volcanic rock.

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). The tarn is one of two of the same name in the Lake District. A second, much smaller Red Tarn lies between Pike of Blisco and Cold Pike, west of the Langdales.

Birks is a fell in the English Lake District situated two kilometres south west of the village of Patterdale in the Eastern Fells. The fells summit sits on a shoulder of the north east ridge of the higher and better known fell of St Sunday Crag, by which it is dominated, walkers often pass over the top of Birks either climbing or descending from the larger fell. The fell's name means a place where Birch trees predominate.

St Sunday Crag is a fell in the English Lake District, part of the Fairfield group in the Eastern Fells. It is a prominent feature in the Patterdale skyline, with a distinctive rounded shape. Indeed, it figures so finely in views from the upper reach of the lake that it is sometimes referred to as ‘the Ullswater Fell’.

Great Dodd (meaning: big round hill) is a mountain or fell in the English Lake District. It stands on the main ridge of the Helvellyn range, a line of mountains which runs in a north–south direction between the lakes of Thirlmere and Ullswater in the east of the Lake District. Great Dodd, with a height of 857 metres (2,812 ft) is the highest of the fells in this range to the north of Sticks Pass. Walkers may approach Great Dodd from either High Row near Dockray to the east, or from Legburthwaite to the west – or along the main ridge track from either north or south. Scramblers with climbing skills may be attracted to three gill climbs on the western side of the mountain. The summit of Great Dodd is a smooth, grassy, rounded dome, like its two southern neighbours, Watson's Dodd and Stybarrow Dodd. Together, these three are sometimes called ‘The Three Dodds’. These three are made of volcanic rocks of the Borrowdale Volcanic Group, and the tops of all three are covered by the same sheet of rock, which was formed in a series of huge volcanic explosions accompanying the formation of a volcanic caldera about 450 million years ago. Two attempts were made to mine mineral veins in the rocks of Great Dodd, but neither attempt was successful.
