The Vale of Pickering (the Vale) is located in East Yorkshire, Eastern England, approximately 10 km to the southwest of Scarborough. During the Quaternary geological period, the Vale lay just to the south of the maximum limit of the Late Devensian glaciation (Figure 1) — the last major glaciation to affect the UK (Bowen et al., 1986[1]; Clark et al., 2012[2]; Böse et al., 2012)[3].

The Vale forms a broadly west-east trending area of low-lying ground that is bounded to the north by the Tabular Hills, to the south by the Howardian Hills and Yorkshire Wolds (Figure 2). In contrast to the surrounding hills, the relief of the Vale is relatively flat with few notable hills or visible deep valleys. This distinctive landscape reflects a relatively complicated recent geological history that was produced by a range of geological processes. The latter stages of its geological development occurred when the Vale was impounded to the west (Vale of York ice) and east (North Sea ice) by lobes of the last British-Irish Ice Sheet and a vast glacial lake formed (Kendall, 1902[4]; Murton and Murton, 2012 [5]; Bateman et al., 2015)[6]. This lake appears to have been linked to an adjacent glacial lake — Lake Flixton, situated to the east of the Vale (Candy et al., 2015[7]; Palmer et al., 2015)[8], with their water levels and patterns of sedimentation patterns apparently controlled by ice-damming and overspill (Murton and Murton, 2012)[5].

The scope of this report is two-fold: firstly, to provide a brief and easily-understandable overview of the recent geological evolution of the Vale of Pickering (see The Quaternary history of the Vale of Pickering); and secondly, to summarise the various datasets that provide information about the Vale (see Relevant geological data, Review and interpretation of selected Single Onshore Borehole Index logs and Cross section interpretation.
