The road climbs out of West Allendale. Pull up too m or so after a lane forks left to Ouston and Ninebanks. Looking south-southeastwards up the dale, an asymmetrical cross profile is apparent, typical of all of the North Pennine dales which are aligned transverse to ice movement. Valley sides facing into the direction from which the ice was flowing — in this case the eastern side — have been selectively steepened by glacial erosion, while the opposite, lee sides are gentler. The lee sides were also the main locus of till deposition, and the asymmetric distribution of till in valleys is well seen on B.G.S. Sheet 25 Alston. Additionally, the up-glacier facing, steepened slopes of the Pennine dales exhibit well-developed structural benching, reflecting variations in resistance to erosion of the Yoredale strata, and this is probably also a consequence of active glacial erosion on these exposed valley slopes.

The road continues towards the summit of Whitfield Moor. Just before rounding the corner at [NY 748 520] there is, to the left, an excellent cross-sectional view of the spectacular glacial meltwater channel described at Locality 4.
