Pen Yr Helgi Du
Pen yr Helgi Du (Head or Hill of the Black Hound) is a mountain peak in the eastern part of the Carneddau in Snowdonia, Wales. It lies on the south-eastern flanks of Carnedd Llewelyn, and is linked to Carnedd Llewelyn over the col of Bwlch Eryl Farchog, a knife-edge ridge over the cliffs of Craig Yr Ysfa. From here the walker can drop down into Cwm Eigiau to the east or to the Ffynnon Llugwy reservoir to the south. Continuing over Pen yr Helgi Du to the east you will reach the even more beautifully named Pen Llithrig y Wrach Pen Llithrig y Wrach is a mountain peak in Snowdonia, Wales. It is one of the four Marilyns that make up the Carneddau range. To the east is Creigiau Gleision, another Marilyn, while to the west is Pen yr Helgi Du and Carnedd Llewelyn. Crai ...

The Hewitt classification was suggested by Alan Dawson in his 1992 book, "The Relative Hills of Britain". Dawson originally called his Hewitts "Sweats", from "Summits - Wales and England Above Two thousand", before settling on the label Hewitt. In a series of three booklets edited by Dave Hewitt, the list of English Hewitts was published in 1997, and the list of Welsh Hewitts was also published in 1997, and the list of Irish Hewitts was published in 1998. Hewitts were designed to address one of the criticisms of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnedd Llewelyn
Carnedd Llewelyn, also spelled Carnedd Llywelyn, is a mountain massif in the Carneddau range in Snowdonia, north-west Wales. It is the highest point of the Carneddau and the second highest peak by relative height in Wales, 49th in the British Isles and lies on the border between Gwynedd and Conwy. Topography and ascent routes Carnedd Llewelyn lies in the middle of the main north-east to south-west ridge of the Carneddau, between Carnedd Dafydd to the south-west and Foel Grach to the north. A short subsidiary ridge links it to Yr Elen to the north-west. It can be climbed from Gerlan, above Bethesda, taking the path following Afon Llafar then continuing to the summit of Yr Elen before following the short ridge to Carnedd Llewelyn. Another path starts from Helyg on the A5, taking the track to the reservoir then following the slopes above Craig yr Ysfa to the summit. An alternative is to reach it by following the main ridge, either from Pen yr Ole Wen or from F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountains And Hills Of Snowdonia
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Pen Llithrig Y Wrach
Pen Llithrig y Wrach is a mountain peak in Snowdonia, Wales. It is one of the four Marilyns that make up the Carneddau range. To the east is Creigiau Gleision, another Marilyn, while to the west is Pen yr Helgi Du and Carnedd Llewelyn. Craig Eigiau and Llyn Eigiau can be seen to the north, while Gallt yr Ogof, Glyder Fach and Tryfan can be viewed to the south. It has one of the more colourful names of any British mountain, translating as ''slippery peak of the witch'', perhaps in reference to the boggy conditions underfoot, or because of the resemblance of its pointed profile to an archetypal witch's hat. It is an outlier of the Carneddau, the higher peaks of which can be reached from Pen Llithrig y Wrach via Pen yr Helgi Du. On its eastern side, the mountain slopes steeply down to Llyn Cowlyd. It may be climbed from the southern side, from Capel Curig or the A5, or from the north-east, from Dolgarrog or Tal-y-bont in the Conwy valley , name_etymology = , i ...

Reservoir (water)
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Mountain Pass
A mountain pass is a navigable route through a mountain range or over a ridge. Since many of the world's mountain ranges have presented formidable barriers to travel, passes have played a key role in trade, war, and both Human migration, human and animal migration throughout history. At lower elevations it may be called a hill pass. A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind. Overview Mountain passes make use of a gap (landform), gap, saddle (landform), saddle, col or notch (landform), notch. A topographic saddle is analogous to the mathematical concept of a saddle surface, with a saddle point marking the highest point between two valleys and the lowest point along a ridge. On a topographic map, passes are characterized by contour lines with an hourglass shape, which indicates a low spot between two higher points. In the high mountains, a difference of between the summit and the mountain is defined as a mountain pas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Nuttall (hill)
This is a list of Nuttall mountains in England and Wales by height. Nuttalls are defined as peaks above in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above ; a mix of imperial and metric thresholds. The Nuttall classification was suggested by Anne and John Nuttall in their 1990 two–volume book, "The Mountains of England and Wales". The list was updated with subsequent revised editions by the Nuttalls. Because of the prominence threshold of only , the list is subject to ongoing revisions. In response, Alan Dawson introduced the Hewitts, with a higher prominence threshold of . This was the prominence threshold that the UIAA set down in 1994 for an "independent" peak. In 2010, Dawson replaced his Hewitts with the fully "metric" Simms, consisting of a height threshold of , and a prominence threshold of . However, both the Nuttall and Hewitt classifications have become popular with peak baggers, and both remain in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carneddau
The (lit. 'the cairns'; is a Welsh plural form, and is sometimes anglicised to ''Carnedds'') are a group of mountains in Snowdonia, Wales. They include the largest contiguous areas of high ground (over or high) in Wales and England (although larger areas over 2,000 feet are found in Northern England), as well as six or seven of the highest peaks in the country—the Fifteen Peaks. The range also encloses a number of lakes such as Llyn Cowlyd and Llyn Eigiau, and the Aber Falls waterfall. It is delimited by the Irish Sea to the north, the Conwy valley to the east, and by the A5 road from Betws-y-Coed to Bethesda to the south and west. The area covers nearly , about 10% of the area of Snowdonia. The area is bordered by three main roads—the A55 (to the north), the A5 to the south and the A470 to the east. Geology In common with much of Snowdonia, the rocks forming the Carneddau originated largely during the Ordovician period between 485 and 444 Ma (million years ago). Prin ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges.
