Achness Falls, also known as the Achness Waterfall or Cassley Falls, is a waterfall located on the River Cassley in Sutherland, Scotland, near Rosehall and Invercassley. [1] Its name is derived from the Scottish Gaelic Ach-an-eas, the "field of the waterfall". [2]
The falls descend a narrow gorge with the upper fall being a 6-metre (20 ft) drop. The lower fall is a thin broken sheet of water down about 12 metres (39 ft) of rock and when in spate this becomes a torrent which has several pools providing a means for salmon to ascend. [3] The location is the type locality and best-studied area of the Achness Thrust, a thrust fault which dips 40 to 50° to the south at the falls. [4] Present nearby are the ruins of a broch and a more modern chapel. [2] By the side of the river is an old cemetery and there are woodland walks. [3]
Atlantic salmon fishing on the River Cassley has a long history. Achness Falls is a temporary barrier to the fish each spring; they do not advance beyond it until the water warms above 10 °C (50 °F). [5] In the late 19th century, plans to destroy the waterfall to improve the salmon run were considered. [6]
A fall of water is an area where water flows over a vertical drop or a series of steep drops in the course of a stream or river. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.
The River Don is a river in north-east Scotland. It rises in the Grampians and flows eastwards, through Aberdeenshire, to the North Sea at Aberdeen. The Don passes through Alford, Kemnay, Inverurie, Kintore, and Dyce. Its main tributary, the River Ury, joins at Inverurie.
Sutherland Falls is a waterfall near Milford Sound in New Zealand's South Island. At 580 metres the falls were long believed to be the tallest waterfall in New Zealand. However, Browne Falls cascades 843 metres down a mountainside in Doubtful Sound, leading some to view that as the tallest.
The River Dee is a river in Aberdeenshire, Scotland. It rises in the Cairngorms and flows through southern Aberdeenshire to reach the North Sea at Aberdeen. The area it passes through is known as Deeside, or Royal Deeside in the region between Braemar and Banchory because Queen Victoria came for a visit there in 1848 and fell in love the place. She and her husband, Prince Albert, replaced an old castle there and built Balmoral Castle.
Ross is a region of Scotland, a former earldom and, under the name Ross and Cromarty, a county. The name Ross allegedly derives from a Gaelic word meaning "headland", perhaps a reference to the Black Isle. Another possible origin is the West Norse word for Orkney – Hrossey – meaning horse island; the area once belonged to the Norwegian earldom of Orkney. Ross is a historical comital region, perhaps predating the Mormaerdom of Ross. It is also a region used by the Church, with the Presbytery of Ross being part of the Synod of Ross, Sutherland and Caithness.
The Moine Thrust Belt or Moine Thrust Zone is a linear tectonic feature in the Scottish Highlands which runs from Loch Eriboll on the north coast 190 kilometres (120 mi) south-west to the Sleat peninsula on the Isle of Skye. The thrust belt consists of a series of thrust faults that branch off the Moine Thrust itself. Topographically, the belt marks a change from rugged, terraced mountains with steep sides sculptured from weathered igneous, sedimentary and metamorphic rocks in the west to an extensive landscape of rolling hills over a metamorphic rock base to the east. Mountains within the belt display complexly folded and faulted layers and the width of the main part of the zone varies up to 10 kilometres (6.2 mi), although it is significantly wider on Skye.
The Ythan Estuary is the tidal component of the Ythan River, emptying into the North Sea 19 kilometres (12 mi) north of Aberdeen, Scotland. The estuary’s tidal action extends a 7 kilometres (4.3 mi) inland and has characteristic widths of between 250 metres (820 ft) and 780 metres (2,560 ft). Besides the tidal channel there are interfaces to the upland dunes including mudflats, sand beaches and shingle flats. Reaches of salt marsh occur, but they are primarily near the Waterside Bridge and the mouth of the Tarty Burn, a small tributary river. Based upon the habitat of the moorland bordering the east of the Ythan River near the mouth, this estuary is the most significant coastal moorland in the northern United Kingdom.
The Battle of Carbisdale took place close to the village of Culrain, Sutherland, Scotland on 27 April 1650 and was part of the Wars of the Three Kingdoms. It was fought by the Royalist leader James Graham, 1st Marquess of Montrose, against the Scottish Government of the time, dominated by Archibald Campbell, 1st Marquess of Argyll and a grouping of radical Covenanters, known as the Kirk Party. The Covenanters decisively defeated the Royalists. The battlefield has been inventoried and protected by Historic Scotland under the Scottish Historical Environment Policy of 2009. Although Carbisdale is the name of the nearest farm to the site of the battle, Culrain is the nearest village.
The River Oykel is a major river in northern Scotland that is famous for its salmon fishing. It rises on Ben More Assynt, a few miles from Ullapool on the west coast of Scotland, and drains into the North Sea via the Kyle of Sutherland. Traditionally it has marked the boundary between Ross to the south and Sutherland to the north.
Ben More Assynt is a mountain in Assynt in the far north-west of Scotland, 30 kilometres (19 mi) north-north-east of the town of Ullapool. The name translates as "big mountain of Assynt", and with a height of 998 metres (3,274 ft) it is the highest point in the county of Sutherland.
The River Cassley in Sutherland, in northern Scotland, joins the River Oykel to form the Kyle of Sutherland at Invercassley. The Kyle is subsequently joined by the River Shin and River Carron before it becomes the Dornoch Firth and enters the North Sea. The main road bridge over the river is at Rosehall, halfway between the mouth and the impressive Achness Waterfall or Cassley Falls.
The Moine Supergroup is a sequence of Neoproterozoic metamorphic rocks that form the dominant outcrop of the Scottish Highlands between the Moine Thrust Belt to the northwest and the Great Glen Fault to the southeast. The sequence is metasedimentary in nature and was metamorphosed and deformed in a series of tectonic events during the Late Proterozoic and Early Paleozoic. It takes its name from A' Mhòine, a peat bog in northern Sutherland.
Rosehall is a remote hamlet near the confluence of the River Cassley and the River Oykel, 1 mile northwest of Altass, in Sutherland, Scottish Highlands and is in the Scottish council area of Highland. It is the site of the main road bridge over the Cassley, which is just downstream from the spectacular Achness Waterfall, commonly known simply as the Cassley Falls.

Falls of Glas Allt is a 50-metre (160 ft) waterfall near the head of Loch Muick, Aberdeenshire, Scotland. Queen Victoria liked to take walks here beside the stream flowing from Lochnagar down to Loch Muick. After the death of Prince Albert she had a cottage, Glas-allt-Shiel, rebuilt for her on the delta where the stream flows into the loch.
Falls of Shin is a waterfall on the River Shin, in northern Scotland, near the villages of Bonar Bridge and Lairg.
