Looking down the Cleveland Way towards the shallow col at the top of Codhill Slack or as Kendall referred to it as Bold Venture Channel. Percy Fry Kendall was Professor of Geology at the University of Leeds from 1904 to 1922 and investigated the glaciation of the North York Moors. He concluded that a lake formed between the east-flowing glacier and the north-facing escarpment which created spillways to the south through nicks in the escarpments at low points such as Bold Venture Channel and Highcliff Gate into Sleddale. Elgee went on to say that if the process had continued Barker’s Ridge with Highcliff Nab on the north end and Codhill Heights on the south would have ended up an outlier like Roseberry. My imagination is curdling.
