The headwaters of the Esk and Duddon are separated by a ridge falling south west from the summit of Crinkle Crags. |} Crinkle Crags is a Fell in the English Lake District in the county of Cumbria. This line of high ground continues over many twists and turns for 15 miles, finally meeting the sea on the slopes of Black Combe. A mile is a unit of Length, usually used to measure Distance, in a number of different systems including Imperial units United States Black Combe is a Fell in the far south of the English Lake District, just four Miles from the Irish Sea. From Crinkle Crags the first fells on this ridge are Hard Knott and Harter Fell, separated by Hardknott Pass. Fell (from the Old Norse fjall, 'mountain' is a word used to refer to Mountains or certain types of mountainous landscape in Scandinavia Hard Knott is a hill in the English Lake District, at the head of Eskdale. Hardknott Pass is a pass that carries a minor road between Eskdale and the Duddon Valley in the English county of Cumbria, England, in the From Harter Fell the ridge continues over Green Crag, Great Worm Crag, Yoadcastle, Whitfell, Buck Barrow and Black Combe. Green Crag is a Fell in the English Lake District. It stands between Eskdale and the Duddon valley in the Southern Fells. Whitfell (or sometimes Whit Fell is a hill in the southwestern part of the Lake District. Alfred Wainwright considered the latter hills unworthy of inclusion in his influential Pictorial Guide to the Lakeland Fells, stating that "south and west from Green Crag the scenery quickly deteriorates. Alfred ("A" Wainwright MBE (17 January 1907 &ndash 20 January 1991 was a British hillwalker, guidebook Author and Illustrator A Pictorial Guide to the Lakeland Fells This summit has therefore been taken as the boundary of fellwalking country. " Later guidebook writers have disagreed, adding and the remainder of the range to their main volumes.  Wainwright himself later relented and included these lesser hills in a supplementary volume, The Outlying Fells of Lakeland.
To the north of Harter Fell is Hardknott Pass, joining Eskdale with the Duddon Valley. There is a steep single-track motor road over the pass with gradients of up to 30% (1 in 3), reaching a maximum height of 393 m (1,290 :ft). The Hardknott Roman Fort stands at a height of approximately 200 m (650 ft) on the lower slopes of the western ridge as it descends into Eskdale. Hardknott Roman Fort was a fort in the Roman province of Britannia. For articles about other places named Eskdale, see Eskdale (disambiguation. A roman road from Ravenglass to Ambleside once crossed the pass, although by a slightly different route.
From the top of the pass a complex series of grassy knolls firms up into a ridge bearing south westward. This steps upward, first over Horsehow Crags and then the impressive gable-end of Demming Crag, before reaching the summit area. Further outcropping rock occurs on all sides, although little of it is of interest to climbers. Notable features are Maiden Castle, Brandy Crag and Mart Crag to the south east and Kepple Crag to the south. To the southwest is a broad and marshy saddle leading onto Green Crag and the moorlands of Birker Fell, the ongoing watershed. Birker Fell is an upland wilderness area in the western portion of the Lake District National Park, in Cumbria, England. The southern and eastern flanks are heavily forested with conifers, legions of Forestry Commission trees sweeping down into the Duddon valley. The Forestry Commission (established in 1919 is a Non-ministerial government department responsible for Forestry in Great Britain.
Harter Fell appears in most views as a conical hill, unsurprising given its broadly circular contours. Wainwright paid it perhaps the ultimate accolade, stating that "Not many fells can be described as beautiful, but the word fits Harter Fell, especially so when viewed from Eskdale. ".
The summit area bears three rocky tors, the middle one of which is the highest. A tor is a rock outcrop formed by Weathering, usually found on or near the summit of a Hill. An Ordnance Survey triangulation column stands on the western outcrop. Ordnance Survey (OS is an Executive agency of the United Kingdom government All three provide pleasant scrambling. From its summit there is an excellent view of the ring of fells known as the Eskdale Horseshoe: Sca Fell, Scafell Pike, Broad Crag, Great End, Esk Pike, Bow Fell and Crinkle Crags. |} Sca Fell (also spelled Scafell, and traditionally ˈskɔːfəl ( Scawfle) though the alternative pronunciation /skɑːˈfɛl/ is common nowadays is a |} At 978 metres (3209 feet Scafell Pike is the highest mountain in England. Broad Crag is a fell in the English Lake District. By some counts it is the fifth highest peak in England |} Great End is the most northerly Mountain in the Scafell chain in the English Lake District. Esk Pike is a Fell in the English Lake District, one of the great cirque of hills forming the head of Eskdale. |} Bowfell (named Bow Fell on Ordnance Survey maps is a Pyramid -shaped mountain lying at the very heart of the English Lake District |} Crinkle Crags is a Fell in the English Lake District in the county of Cumbria. To the south are the sands of the Duddon estuary. 
Harter Fell offers excellent insights into the structure and composition of the Birker Fell formation of the Ordovician Borrowdale Volcanic Group. Birker Fell is an upland wilderness area in the western portion of the Lake District National Park, in Cumbria, England. The Ordovician is a geologic period and system, the second of six of the Paleozoic era, and covers the time between 488 The Borrowdale Volcanic Group is a development of volcanic rocks named after the Borrowdale area of the Lake District, in England. The fell is dominantly composed of composite andesite lava flows, with autobrecciated upper surfaces developed in some locations. For the extinct cephalopod genus see Andesites. Andesite (ˈændəsaɪt is an igneous, Volcanic rock, of intermediate Lava is molten rock expelled by a Volcano during an eruption When first expelled from a volcanic vent it is a Liquid at Temperatures Breccia (ˈbrɛtʃiə ˈbrɛʃiə breach is a rock composed of angular fragments of several Minerals or rocks in a matrix, that is a cementing material These are often seen in the field as flat surfaces above steep crags, the crags themselves being formed due to the more crystalline, lower portions of each flow. The dip slope on these flows (~24° WSW) suggests that the formation is in nearly the same orientation now as when it formed. A dip slope is a geological formation often created by Erosion of tilted strata. The summit of the fell is composed of one such lava flow, but only a few metres down slope the underlying lava flow is a portion of the Great Whinscale Dacite. Dacite ( deɪsaɪt) is an igneous, volcanic rock with a high iron content This local marker unit conformably overlies an andesitic lapilli tuff and the Little Stand Tuff, a nodular rhyolitic ignimbrite. Lapilli is a size classification term for Tephra, which is material that falls out of the air during a volcanic eruption. Tuff (from the Italian "tufo" is a type of rock consisting of consolidated volcanic ash ejected from vents during a volcanic eruption This page is about a volcanic rock For the ghost town see Rhyolite Nevada, and for the satellite system see Rhyolite/Aquacade. Ignimbrite is a Volcanic Pyroclastic rock often of Dacitic or Rhyolitic composition Below these distinctive rock units the andesite lava flows are seen again. On the northern side of the fell, at approximately 520-540m elevation, a volcaniclastic sandstone unit is intercalated between the flows. Pyroclastic rocks or pyroclastics (derived from the Greek πῦρ, meaning fire and κλαστός, meaning broken are Clastic rocks Sandstone is a Sedimentary rock composed mainly of Sand -size Mineral or rock grains. Also on the northern slopes of the fell, and lower still at between 450-500m, the lava flows switch to dacitic composition, with distinctive euhedral plagioclase feldspar phenocrysts (1-4mm). Euhedral Crystals are those that are well-formed with sharp easily-recognized faces Plagioclase is a very important series of tectosilicate Minerals within the Feldspar family Feldspar is the name of a group of rock-forming Minerals which make up as much as 60% of the Earth 's crust. A phenocryst is a relatively large and usually conspicuous Crystal distinctly larger than the grains of the rock groundmass of a Porphyritic Igneous The southern slopes of the fell again display the Great Whinscale dacite-tuff sequence, owing to extensive faulting. The very lowest slopes of the fell again revert to andesitic lava flows. In the north-western corner, near the Spothow Gill, a small vein of copper mineralisation has been worked out, and some of the evidence of this Victorian-era mining activity can still be seen. In Geology, a vein is a finite volume within a rock, having a distinct shape filled with Crystals of one or more Minerals which were precipitated Copper (ˈkɒpɚ is a Chemical element with the symbol Cu (cuprum and Atomic number 29 An ore is a volume of rock containing components or Minerals in a mode of occurrence that renders it valuable for mining
From Eskdale Harter Fell can be climbed from Jubilee Bridge in the west or from the summit of Hardknott Pass in the east. From the Duddon, walkers can make use of the car parking at Birks Bridge. This provides a reasonably direct line from the west. An alternative is to start from Fickle Steps and circuit clockwise around the fell to join the path from Jubilee Bridge.
