The Ochil Fault is the geological feature which defines the southern edge of the Ochil Hills escarpment in Scotland. The plateau is undulating with no prominent peak, the highest point being Ben Cleuch at 721 m (2,365 ft). Illustrated with many diagrams and drawings and some photographs. Alluvial gold is wide-spread and locally abundant in the central Ochil Hills, but the bedrock sources have not been identified. In the past they [3][4] The name may involve *ogel meaning, "a ridge". They also acted as a boundary with Fife. The North Fife Hills form a continuation of the Ochil Hills and are separated from the rest of Fife by Stratheden, extending north-east from Loch Leven to the sea near Leuchars. The minerals, including ores of silver and cobalt, were probably emplaced by hydrothermal solutions percolating upwards through various minor faults and fractures, in the Tertiary period. The Ochils Mountain Rescue Team consists of 35 volunteer mountaineers with specialist training who "locate and recover people who find themselves in difficult situations in the outdoors."[12]. Edinburgh : HMSO, 1970 The highest levels – Innerdouny (497 metres) and Mellock (479 metres) – are in the west, heights decreasing gradually to below 150 metres in the area north of Auchtermuchty . North of the fault, The Ochil Fault has produced one of the best examples of a fault line scarp to be seen in Britain. The hills are part of a Devonian lava extrusion whose appearance today is largely due to the Ochil Faultwhich … A scarp is a steep slope and that is exactly what you can see rising up above the low-lying Clackmannanshire plain. Peaks over 3,000 ft (914.4 m) are known as Munros. Glacial till covers much of the lower ground around and within the range and peat accumulations occur on the plateau surface particularly in the west.[7]. Subsequent glacial erosion has served to highlight this giant step in the landscape. 243 at the surface between the Ochil Hills and Stirling. The Ochil Hills were a popular destination for panners in the 1990s. Geography and geology The hills are part of a Devonian lava extrusion whose appearance today is largely due to the Ochil Fault which results in the southern face of the hills forming an escarpment.

Local historians have struggled to discover exactly the identity of "Katie Thirsty", but Pictish researcher Ronald Henderson argues that "the name derives from a corruption of both St. Katherine of Alexandria [Katie] and the Pictish King, Drust or Drustan [Thirsty]." Since 1846 small shocks have been observed at Comrie on a regular, if infrequent, basis. There were several excellent locations but the most productive, Borland Glen (7), yielded gold with a distinctive telluride signature in … Ancient folklore and historical documentation suggests that the Ochils once were inhabited by the Picts, or at least that a few Pictish settlements existed in the Ochil Hills. Following approval in early 2007, the construction of a wind farm consisting of thirteen 102 m (335 ft) turbines on Burnfoot Hill, which lies north of Tillicoultry and Ben Cleuch and to the south of the Upper Glendevon Reservoir has been completed. Immediately to the north is the campus of Stirling University and Airthrey Loch. The oldest rocks cropping out in the County are of the Ochil Volcanic Formation in the Ochil Hills. The Ochil Fault, one of the most prominent tectonic features in the Midland Valley of Scotland, juxtaposes Lower Devonian volcanic rocks against late Westphalian strata, implying a possible vertical displacement of … The formation comprises over 2000m of subaerial basaltic and andesitic lava flows with interbedded terrestrial debris-flow conglomerates. The highest point is Ben Cleuchin Clackmannanshireat 2,365 feet. [5], The Ochil Volcanic Formation, a sub-unit of the Arbuthnott-Garvock Group, consists of basaltic andesite and trachyandesite lavas and related rock types erupted during the Early Devonian epoch. The hills are part of a Devonian lava extrusion whose appearance today is largely due to the Ochil Fault which results in the southern face of the hills forming an escarpment. The name Ochil, recorded as Okhel in the 13th Century, is of Pictish origin. The Ochil Fault is one of Britain's finest examples of a fault line scarp,[4] and can be best appreciated from vantage points such as the Wallace Monument near Stirling. Alluvial gold is wide-spread and locally abundant in the central Ochil Hills, but the bedrock sources have not been identified. A notional boundary for the Ochil Hills is shown in Map 2, bounded by roads, and stretching from Dunblane in the west to Glen Farg in the east. "[9], An 18-turbine development, approved in June 2006, has been constructed at Green Knowes, south of Auchterarder, north of Glendevon about 400 m (1,300 ft) north of the Ben Thrush summit. In the southern part of East Fife the hills are relatively isolated, e.g. He goes on to say "that the great crags of Dumyat less than a mile to the east is universally credited with being the last Pictish stronghold at the old hillfort there.

The Ochil Fault, one of the most prominent tectonic features in the Midland Valley of Scotland, juxtaposes Lower Devonian volcanic rocks against late Westphalian strata, implying a possible vertical displacement of … It is intruded by numerous dykes of micridiorite of Silurian/Devonian age which form a part of the North Britain Siluro-Devonian Calc-alkaline Dyke Suite. Our latest film, narrated by Dr Kirsty McAlister, explores the various ways in which people's lives have been influenced by the Ochil Hills. "[8]Old lore also told that some of the stones from the fort of Castle Craig were used in the construction of Stirling Castle, 7 3⁄4 miles (12.5 kilometres) to the west. Title: 4. Because the deposits thin towards the north, and there are few signs of volcanic necks within the Ochil Hills themselves, it is thought that the eruptive centres were south of the fault, however these are buried deep beneath the Carboniferous rocks including coal measures which are found beneath the low-lying carse lands to the south.[1]. A band of this formation runs from Gargunnock to the Clyde ; and 1 believe there are quarries in it near Gargunnock, but have not seen them myself. Peat Hill, Lamb Hill, and Gled’s Nose are a selection of “hills” marked on OS Maps near NN 9768 0247. There are ranges of gentler, rolling hills even in the central lowlands of Scotland.

Oblique aerial photograph of the line of the Ochil Fault, Ochil Hills, Stirlingshire. These hills have no distinguishable summit, disqualifying them as “peaks” in the Ochils, but rather they lead onto Glenquey Hill and Innerdownie respectively. In the upper part of the volcanic sequence there These occurred in the form of basins, and the pattern of movements was complex, however it is known that the greatest vertical movement was centred about 1 km east of the town of Alva, and almost certainly exceeded 5 km vertically. Ochil Volcanic Formation and the Quaternary of Glen Devon August 9th 2003. [10] The windfarm is owned and run by EDF Renewables, who support the work of the Ochils Mountain Rescue Team through the Burnfoot Hill Community Fund with an annual donation of £5,000 guaranteed till 2039.
