The Wharfedale valley was cut into the shape we know today during the last ice age. The valley was transformed into its classic U-shaped state between 18,000 and 12,000 years ago by the Wharfedale Glacier, though this was cutting through a channel that had already had a river draining water away to the east through what is now Wharfedale, and also to the north through what is now Bishopdale and then Wensleydale. Evidence of human settlement has been found dating back to Neolithic times and the valley has plenty of artefacts relating to the Celtic, Roman and Anglo-Saxon periods. The Romans built a road over Stake Moss into what is now the village of Bainbridge in Wensleydale. The Anglo-Saxon influence remains in modern times, with most settlements in Upper Wharfedale having Anglo-Saxon derived names. The name of the valley is derived from the principal river that flows through it: the Wharfe, which comes from the Old EnglishWeorf or Old NorseHverfr, with both taken as meaning winding river. The River Wharfe starts at the confluence of the Oughtershaw Beck and the Green Field Beck, each of which originates at the Pennine watershed, some north-east of Ribblehead. The valley roughly follows a south-easterly direction, providing a border between West Yorkshire and North Yorkshire. Between Oughtershaw Moss and Wetherby, the valley runs for. The uppermost part of the valley is known as Langstrothdale. Below Beckermonds the river is known as the River Wharfe. Wetherby is traditionally seen as the foot of Wharfedale, even though the river continues on through the Vale of York. The valley has been used largely for agriculture, and is now criss-crossed with stone walls and stone barns that evidence its use down the centuries.
Geology
The geology of the valley is split, with Upper Wharfedale consisting of carboniferous limestone of the Yoredale series. In the lower part of Wharfedale, around Ilkley and Otley, the underlying stone is mostly millstone grit, which can be seen best at the Cow and Calf rocks on the south side of the valley on Ilkley Moor.
In 2017, in consideration of regional geography, the Church of England changed its subdivisions and re-grouped the Deanery of Wharfedale with that of South Craven, in order that the similar regions can work together more effectively.
Wharfedale in culture
One of the most renowned painters of the Victorian era, John Atkinson Grimshaw, portrayed the area in his piece, "Moonlight, Wharfedale". He is known as one of the best and most accomplished nightscape and townscape artists of all time, and this painting is a prime example of his mastery. JMW Turner also visited and painted scenes around Otley and Ilkley. Turner was commissioned to paint Kilnsey Crag, which he created as an oil painting in 1816. The valley was featured in episode three of the BBC Two series, The Yorkshire Dales.
