Yorkshire Dales - Ascent of Ingleborough (2,372 ft)

Taken on the 20th August 2014, this video films the ascent of Ingleborough, one of the Yorkshire Three-Peaks. It was over cast when we set off on the 30 or so mile drive to the base of Ingleborough. But the more we climbed the more the day improved and by the time we were heading back down, the sun was well and truly out. The clouds shadows rolling over the surrounding land was impressive. The views from the top are stunning, look out for the tallest of the three peaks 'Whernside' in the distance, to the left the huge Morecambe bay, to the North peaks visible from the Lake District.

Ingleborough is the second highest mountain in the Yorkshire Dales, at 723 metres (2,372 ft). It is one of the Yorkshire Three Peaks, the other two being Whernside, at 736 metres (2,415 ft), and Pen-y-ghent, at 694 metres (2,277 ft). Ingleborough is frequently climbed as part of the Yorkshire Three Peaks Challenge, which is a 24-mile (38-km) circular challenge walk starting and finishing in Horton in Ribblesdale. If done anti-clockwise Ingleborough is the last mountain climbed, and ascent is from Chapel-le-Dale.

The striking appearance of Ingleborough from all directions and from a great distance is due to the unusual geology of the underlying rock. The base of the mountain is composed of ancient Silurian and Ordovician rocks which are exposed in the valley bottoms to the north of Ingleton. A belt of Carboniferous Limestone, the 'Great Scar Limestone', some 600 feet (180 m) thick, lies on top of this. Due to the limestone's permeability, all the streams flowing down from the mountain are engulfed upon reaching it, falling into a number of potholes. Above lies the layered Yoredale Series of sedimentary rocks, predominantly shale and sandstone, and generally concealed by the peat but revealed in the escarpments about 1,700 feet (520 m) up. There are also layers of harder limestone sandwiched between the softer rocks which have been eroded faster, and which protect the layers beneath them, leading to the 'tiered' effect. The whole mountain, however, is protected from erosion by a cap of Millstone Grit approximately 100 feet (30 m) tall. The rock above the Millstone Grit layer has been eroded away, which explains the flatness of the summit.
