A strath is a large valley, typically a river valley that is wide and shallow (as opposed to a glen, which is typically narrower and deep). [1]

Word and etymology

An anglicisation of the Gaelic word srath, it is one of many that have been absorbed into the English and Scots languages. It is commonly used in rural Scotland to describe a wide valley, even by non-Gaelic speakers.

In Scottish place-names, Strath- is of Gaelic and Brittonic origin. [2] Strath- names has a similar origin to Gaelic srath, meaning "broad-valley", as well as to Cumbric and Pictish cognates (cf. Welsh ystrad). [2]

Gaelic srath is derived from Old Irish srath, recorded as having meant "grassland". [3] The modern Scottish Gaelic sense of "broad-valley", paralleling the meaning of Brittonic cognates, developed from substrate influence from Pictish. [3]

Toponymy

It occurs in numerous place names within Scotland including Strathmore, Strathspey and Strathclyde. Abroad, many places with Scottish heritage also use the prefix, including Strath-Taieri in New Zealand; Strathalbyn in South Australia, Strathfield, a suburb of Sydney, Australia; Strathewen, Victoria, Australia; Strathpine, a suburb of Brisbane, Australia; and various places in Canada: Strathmore, Alberta; Strathcona; Strathroy, Ontario; and Strathburn, Ontario.

It also occurs in the names of five Peninsular and Oriental Steam Navigation Company liners, four of which, the Strathaird, the Strathnaver, the Stratheden and the Strathmore, carried thousands of migrants to Australia between the 1950s and the 1960s. The ships acted as troop carriers during the Second World War and the fifth ship, the Strathallan, sank in the Mediterranean in 1942 taking troops to the landings in North Africa. [4]

The word is related to Welsh Ystrad, as in Strat Clut, the Old Welsh name for the Kingdom of Strathclyde.

In Keith there is a distillery producing the Strathisla whisky. It is a single malt whisky that is also an ingredient to the blend Chivas Regal.

In geology

In geology, a strath is a bedrock surface within a river valley that marks a base level of erosion by the river. This may underlie a contemporary strath valley floor, corresponding to the present base level, but it may also correspond to a former base level now preserved in the geologic record. [5]

When a river in a strath valley is rejuvenated by a drop in base level, remnants of the former valley floor may be preserved as strath terraces. [6] These may record past climate oscillations [7] [8] or may be a result of river meandering. [9]

If a change in sedimentation rates results in renewed deposition of sediments (aggradation) in a strath valley, the original strath surface may be buried under fresh sediments and become part of the geologic record. For example, at least three such straths are present in the valley of the Rio Grande River near Albuquerque, New Mexico. [10]

<span class="mw-page-title-main">Valley</span> Low area between hills, often with a river running through it

A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas.

<span class="mw-page-title-main">Glen</span> Name for valley commonly used in Ireland, Scotland and the Isle of Man

A glen is a valley, typically one that is long and bounded by gently sloped concave sides, unlike a ravine, which is deep and bounded by steep slopes. The word is Goidelic in origin: gleann in Irish and Scottish Gaelic, glion in Manx. The designation "glen" also occurs often in place names. Glens are appreciated by tourists for their tranquility and scenery.

Pictish is an extinct Brittonic Celtic language spoken by the Picts, the people of eastern and northern Scotland from Late Antiquity to the Early Middle Ages. Virtually no direct attestations of Pictish remain, short of a limited number of geographical and personal names found on monuments and early medieval records in the area controlled by the kingdoms of the Picts. Such evidence, however, shows the language to be an Insular Celtic language related to the Brittonic language then spoken in most of the rest of Britain.

Cumbric was a variety of the Common Brittonic language spoken during the Early Middle Ages in the Hen Ogledd or "Old North" in what is now the counties of Westmorland, Cumberland, northern Lancashire in Northern England and the southern Scottish Lowlands, alongside the Kingdom of Elmet in modern day Yorkshire. It was closely related to Old Welsh and the other Brittonic languages. Place name evidence suggests Cumbric may also have been spoken as far south as Pendle and the Yorkshire Dales. The prevailing view is that it became extinct in the 12th century, after the incorporation of the semi-independent Kingdom of Strathclyde into the Kingdom of Scotland.

<span class="mw-page-title-main">Valley of Strathmore</span>

Strathmore is a broad valley or strath in east-central Scotland, lying between the Grampian mountains and the Sidlaws. It is approximately 50 mi (80 km) long and 10 mi (16 km) wide. Strathmore is underlain by Old Red Sandstone but this is largely obscured by glacial till, sands and gravels deposited during the ice age. Its northeast to southwest alignment is influenced by the underlying geological structure of the area which reflects the dominant Caledonian trend of both the central lowlands and the Highlands of Scotland; its northern margin reflects the presence of the Highland Boundary Fault. Strathmore is fertile and has some of Scotland's best arable farmland, producing soft fruits and cereals.

Yr Hen Ogledd, or in English the Old North, is the historical region that was inhabited by the Brittonic people of sub-Roman Britain in the Early Middle Ages, now Northern England and the southern Scottish Lowlands, alongside the Celtic Kingdom of Elmet. Its population spoke a variety of the Brittonic language known as Cumbric which is closely related to, if not a dialect of Old Welsh. The people of Wales and the Hen Ogledd considered themselves to be one people, and both were referred to as Cymry ('fellow-countrymen') from the Brittonic word combrogi. The Hen Ogledd was distinct from the parts of North Britain inhabited by the Picts, Anglo-Saxons, and Scoti.
