Teesdale is a dale, or valley, of the east side of the Pennines in County Durham, England. Large parts of Teesdale fall within the North Pennines Area of Outstanding Natural Beauty (AONB) - the second largest AONB in England and Wales. The River Tees rises below Cross Fell, the highest hill in the Pennines at 2,930 feet (890 m),[1] and its uppermost valley is remote and high. The local climate was scientifically classified as "Sub-Arctic" and snow has sometimes lain on Cross Fell into June (there is an alpine ski area Yad Moss).[2][3]

Geology[edit]

Unusually for the Pennines, rock of igneous origin (the Whin Sill) contributes to the surface geology and scenery of Teesdale. Around 295 million years ago upwelling magma spread through fissures and between strata in the earlier Carboniferous Limestone country rock. As it cooled (an event which is believed to have lasted 50 years) the rock contracted and caused itself to split into vertical columns. The heating of the limestone above the roack also caused it to be turned into a crumbly marble known as Sugar Limestone.[4][5]

Economic deposits in Llandovery rocks include soft shales that were previously worked to be used as slate pencils.[6]

More recently, Ice Age glacial activity shaped the valley, and much of the pre-glacial river course is now buried beneath glacial drift.

Botany[edit]

In places this impervious dolerite rock, with shallow soil above it, prevented the growth of scrub or trees: this enabled certain post-glacial Arctic / Alpine plants to survive here when elsewhere as a rule they were overgrown. The Sugar Limestone formed by thermal metamorphism of the limestone into which the Whin Sill was intruded also meets the requirements of some of these plants. Teesdale is famous among naturalists for the "Teesdale Assemblage" of plants found together here that occur widely separated in other locations, abroad or in the British Isles.[7]

Part of Upper Teesdale near the Cow Green Reservoir is designated a National Nature Reserve; it contains the unique Teesdale Violet and the blue Spring Gentian as well as more common Pennine flowers such as rockrose, spring sandwort, mountain pansy, bird's-eye primrose and butterwort.[8] Hay meadows in the valley above High Force, some now carefully cultivated to ensure this, contain an extremely rich variety of flowering plants including globe flower, wood cranesbill and Early Purple Orchid.[9] On the south bank of the Tees near High Force can be seen the largest surviving juniper wood in England.[10]

Geography and history[edit]

Teesdale's (and the west side of County Durham's) principal town and most populous settlement is Barnard Castle,[11] a historic market town that is home to the renowned Bowes Museum.[12] It also includes the small town of Middleton-in-Teesdale and a number of villages, including Mickleton, Eggleston, Romaldkirk and Cotherstone.[11] Middleton-in-Teesdale was a lead-mining centre,[13] and plentiful traces of this industry can be seen round the adjoining slopes and side-valleys.[14] On the south side of Teesdale looms the Bronze Age burial site of Kirkcarrion.[15]

Over ledges in the Whin Sill fall the famous waterfalls of High Force and Low Force and the cataract of Cauldron Snout.[16]

Teesdale gave its name to the former Teesdale district of County Durham, although the south side of Teesdale lies within the historic county boundaries of the North Riding of Yorkshire. Formerly the Startforth Rural District, it was transferred to County Durham for administrative and ceremonial purposes on 1 April 1974, under the provisions of the Local Government Act 1972. All of Teesdale lies within the parliamentary constituency of Bishop Auckland (County Durham). Teesdale itself has been described as being the area between the source of the River Tees to a point just west of Darlington where the tees flows through flatter country known as the Tees Valley.[17]

The River Tees flows through Teesdale before reaching and passing between Barnard Castle and Startforth, thereafter passing to the south of Darlington, reaching the North Sea south of Hartlepool after passing Stockton-on-Tees and Middlesbrough. Running roughly parallel to Teesdale to the north is Weardale.

Crime[edit]

In 2009, a league table of burglary "hotspots" in England and Wales was published. In it, it was revealed that Teesdale has fewer burglaries than any other part of the country. In 2008, only 14 burglaries were committed, or 1.2 for every 1,000 homes.[18]
