Great Wold Valley

The Great Wold Valley is the largest and broadest of the valleys cutting into the Yorkshire Wolds. It carries the Gypsey Race, an intermittent stream, which runs from its source Wharram-le-Street eastwards along and through the northern Yorkshire Wolds to reach the sea at Bridlington.

It is known that the Great Wold Valley was an important place of worship during Neolithic times and there are a number of scheduled monuments in the valley. There are two dramatic right angle bends in the course of the Gypsey Race, one turning to the south at Burton Fleming then another turning eastwards again at Rudston. This intermittent and irregular watercourse is believed to be affected by a siphoning action in underground reservoirs and can come into flood apparently regardless of recent rainfall in the local vicinity. This seemingly magical property is thought to be responsible for the number of significant neolithic sites along its course, including the Rudston Monolith and the ancient burial mounds of Willy Howe and Duggleby Howe. Howe, in this case a topographic name from Middle English, originated with the Old Norse word haugr meaning a small hill or a man-made mound or barrow.

The underlying bedrock of the valley is chalk which was laid down in the Cretaceous geological period. On the sides of the valley wind blown sand and loess overlay the chalk and in the valley bottom alluvium covers undifferentiated deposits of fragmented chalk which were eroded from the hillsides in the Devensian period of the Ice Age. In pre glacial times the Great Wold Valley was the seaward outlet of the River Ure from Wensleydale but the ice sheets in the Vale of York blocked and then permanently altered the course of the Ure.
