Tarn Wadling
From Wikipedia, the free encyclopedia

Tarn Wadling (formerly spelled Turnewathelane, Terne Wathelyne,[1] among others) was a lake between Carlisle and Penrith, near the village of High Hesket[2] in Cumbria, England. In the Middle Ages, it was famous for its carp, but it was drained in the 19th century, and is now no more than a depression. The name remains today in a small woodland governed by the Woodland Trust.[3]
Throughout the Middle Ages and in later folklore the tarn was associated with spectral appearances and functioned as a liminal place between the regular world and fairyland; it occurs in three Arthurian poems, all involving Sir Gawain.
Origin and geology


The lake started as a kettle hole (a hole formed by a block of ice left by a retreating glacier). Various reported sounds (supposedly the pealing of a bell) could have been caused by the emission of methane. The appearance of an island (reported in 1810) could have been caused by a chunk of vegetation coming up from the bottom.[3]
A geological description of the tarn was published by D. Walker in 1964. Walker described a "depression", some 600 yards in diameter. When glacial ice withdrew it left the hollow, though at a later stage, the "Scottish Readvance Glaciation", when ice advanced again to within a few kilometers, it was part of a much larger glacial lake, whose surface was at 440 feet (133 m) elevation. The former lake is now mostly filled with red sand, with silty mud on top. On the northwest edge of the former lake is a small bog called Crane Moss, above what used to be the shoreline.[4]
Middle Ages
The lake was one of two lakes in Cumbria to appear on the Gough Map, the oldest road map of England. It is drawn considerably larger than Windermere, though that lake is almost forty times bigger; this can be explained, says Kathleen Coyne Kelly, following Daniel Birkholz's argument in The King's Two Maps (2004), by the political interest that underlies the Gough Map, which was used by Edward I of England to confirm his claims to Wales and Scotland. Tarn Wadling is important (more so than Windermere) because it is connected to King Arthur, who supposedly conquered Scotland—and Edward I claimed Arthur as an ancestor.[a] The Gough Map was a model for many others, including a map found in a sixteenth-century commonplace book, which also singles out Tarn Wadling graphically, with "zigzagging lines evok[ing] the sharpness of its surface wave".[6][5] It seems there are no depictions of the tarn on any subsequent maps until the nineteenth century.[5] The current two woodlands are the remains of a much larger wooded area that grew on the shores of the lake.[b] It is also mentioned in the Domesday Book. The woods go back to at least the 1600s, since all the woods in the area are designated as Ancient Semi-Natural Woodland or Planted Ancient Woodland. Today's Scots pine trees may have come from a line of trees that lined the drovers' road to the lake, adding to its historical significance.[2]
The lake was owned by the Armathwaite Nunnery, and the Augustinians of the Diocese of Carlisle had fishing rights to the lake.[3] The tarn was "famed for its production of the finest carp".[7] As a fishery, its documented reputation goes back until at least the thirteenth century, when Carlisle's prior claimed a tithe on all fish from the lake.[8][9] In the early fourteenth century, John de Crumwell, keeper of the forests north of the river Trent, allowed the Bishop of Carlisle to take fifty pike from the lake so he could restock his own ponds. Eels may have been fished as well. Later the Duke of Gloucester (the later Richard III of England) leased the lake.[9]
William Hutchinson, in his 1794 History of the County of Cumberland, provided a description of the tarn. At the time it covered about a hundred acres and belonged to a William Henry Milbourne, who also owned Armathwaite Castle. Hutchinson noted the quality of the carp, and gave a description of the lake that,[10] as F. H. M. Parker pointed out in 1909, already indicated it was precariously situated:[9]
This lake is in a remarkable situation, bordering upon a declivity, which descends towards the river for near a mile, and lies about six hundred perpendicular feet above the level of Eden, capable of being drained by a cut over a very narrow bank of earth.[10]
The boggy area was suitable for growing cranberries,[11] and important finds of beetles were made there, including the first Notiophilus rufipes in the British Isles. It was also a stopping place for waterfowl.[12] Some of these details—the carp, the waterfowl—are also found in a description from 1802, quoted by David E. Bynum:
Tarn-wadling spreads its waters on a naked and barren common, about one mile west from the river Eden, at Armathwaite, above which it rises 600 feet perpendicular. It covers about 100 acres, and is much frequented by wild fowl: the carp it produces are extremely fine.[13]
In 1816 it was owned by a Mr. Milbourne, according to Daniel and Samuel Lysons, the lord of the manor who owned the Castle Hewen, situated "on a lofty eminence near this tarn" (and thus having military potential). Bynum cites a source from 1895, which notes that it "has been filled up and converted into grazing land", and by 1932 it was still remembered, though its exact location was not clear, the location being incorrectly reported by John Bartholomew in the Survey Gazetteer of the British Isles.[13]
In the 1850s, the Earl of Lonsdale drained the lake, possibly in order to have an area for training racehorses.[2][c] By 1907 Howard Maynadier described it as "a sedgy swamp where cattle feed".[14] It filled again, partly: people skated on the ice in 1939.[2] In the 1940s it was drained again, by Italian POWs,[15] to create farmland. It is now just a "shallow dip in the ground".[2] A boathouse remains.[3]
Current status

What is now called Tarn Wadling is a small wooded area on the former shoreline on the southern part of the tarn, with 120-year-old Scots pine and over 60-year-old birch. It is administered by the Woodland Trust,[2] which bought it in 1997.[16]
Tarn Wadling occupies 0.55 hectare, and is a rectangular area occupied by mostly mature woods surrounded by farmland; isolated from buildings and roads, it sees few visitors. The area is surrounded mostly by fences, with the remains of dry stone wall on the northwest and northeast boundaries. 2/3 of it is occupied by Scots pine, planted ca. 1880, and birch have moved in ca. 1950–1960, especially on the edges where there is sufficient light. In the southern part is an area, about 1/3 of the total property, which was planted in 1998, with Scots pine, oak, ash and cherry.[2]
Access for pedestrians and woodland managers is via an unclassified road that runs east from the A6, near High Hesket, toward Armathwaite. There is room for two cars to park at the entrance to the wood, adjacent to an access gate for management.[2]
