Pen Yr Ole Wen
Pen yr Ole Wen is the seventh highest mountain in Snowdonia and in Wales. It is the most southerly of the Carneddau range. The mountain lies to the north of Idwal Cottage youth hostel on the A5 road, from where it has a pyramidal appearance. It may be climbed from the hostel by a path that leads directly up the south west "corner", climbing 675 m in about 1.5 km (i.e. an average gradient of nearly 1 in 2). A slightly easier ascent involves starting from Tal-y-Llyn Ogwen, about a mile north-east from the hostel, following the stream until nearing the outflow from the mountain lake Ffynnon Lloer Ffynnon Lloer (Welsh : ''Source of heMoon'') is a lake in the Carneddau range of mountains in Snowdonia, North Wales. It lies below the peaks of Pen yr Ole Wen and Carnedd Dafydd at a height of and covers an area of some . The remains of two ... and then branching left to take the path up the ridge.

Llyn Ogwen
Llyn Ogwen (; ) is a ribbon lake in north-west Wales. It lies alongside the A5 road between two mountain ranges of Snowdonia, the Carneddau and the Glyderau. Somewhat unusually, the county boundary at this point is drawn so that the lake itself lies in the county of Gwynedd, but all the surrounding land (excluding the outflow) lies in Conwy County Borough. Llyn Ogwen lies at a height of about 310 metres above sea level and has an area of , but is a very shallow lake, with a maximum depth of only a little over 3 metres. It is fed by a number of streams from the slopes of the mountains which surround it, which include Tryfan and Pen yr Ole Wen. The largest of these streams is Afon Lloer, which flows from Ffynnon Lloer. It is said that after the Battle of Camlann (King Arthur's final battle), Sir Bedivere (Bedwyr) cast the sword Excalibur into Llyn Ogwen, where it was caught by the Lady of the Lake. Tryfan is said to be Sir Bedivere's final resting-place. According to the wri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gradient
In vector calculus, the gradient of a scalar-valued differentiable function of several variables is the vector field (or vector-valued function) \nabla f whose value at a point p is the "direction and rate of fastest increase". If the gradient of a function is non-zero at a point , the direction of the gradient is the direction in which the function increases most quickly from , and the magnitude of the gradient is the rate of increase in that direction, the greatest absolute directional derivative. Further, a point where the gradient is the zero vector is known as a stationary point. The gradient thus plays a fundamental role in optimization theory, where it is used to maximize a function by gradient ascent. In coordinate-free terms, the gradient of a function f(\bf) may be defined by: :df=\nabla f \cdot d\bf where ''df'' is the total infinitesimal change in ''f'' for an infinitesimal displacement d\bf, and is seen to be maximal when d\bf is in the direction of the gradi ...

Mountains And Hills Of Gwynedd
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 ...

Lists of mountains and hills in the British Isles#Furths, Furths are defined as mountains that meet the Lists of mountains and hills in the British Isles#Munros, classification criteria to be a Scottish Munro, including being over in elevation, but which are ''furth'' of (i.e. "outside" of) Scotland. They are also called Welsh Munros, Irish Munros, and English Munros respectively, or the ''three-thousanders,'' as in ''Welsh 3000s, The Welsh 3000 challenge''. Some Furth definitions add a topographical prominence above , akin to a Scottish Lists of mountains and hills in the British Isles#Murdos, Murdo, however the official Scottish Mountaineering Club ("SMC") lists includes Furths with a prominence below this level.

Scafell Pike
Scafell Pike () is the highest and the most prominent mountain in England, at an elevation of above sea level. It is located in the Lake District National Park, in Cumbria, and is part of the Southern Fells and the Scafell massif. Scafell Pike forms part of the inactive Scafells volcano. Etymology and name history The name ''Scafell'' is believed by some to derive from the Old Norse ''skalli fjall'', meaning either the fell with the shieling or the fell with the bald summit, and is first recorded in 1578 in the corrupted form ''Skallfield''. An alternative derivation is from the Old Norse "skagi", meaning a cape, headland, promontory or peninsula – so giving an etymology that aligns with Skaw in Shetland. It originally referred to Scafell, which neighbours Scafell Pike.Dorothy Wordsworth's ascent of Scafell Pike, 1818, http://www.pastpresented.ukart.com/eskdale/wordsworth1.htm What are now known as Scafell Pike, Ill Crag, and Broad Crag were collectively called either ''t ...
