“…Palmer (, p. 358) argued that there is no evidence of glaciation in the Bristol area. However, Hawkins and Kellaway () concluded the opposite and presented evidence for glaciation of the Bristol district, a situation further advocated by Kellaway (). This was then disputed by Kidson and Haynes () who pointed out that the Burtle beds were estuarine sediments containing Quaternary microfauna from both the current and the last interglacial (i.e.…”

“…The nature of the glacial record in the Bristol area has since remained unclear and the evidence for ice reaching this area is patchy. The best evidence for glaciation in this area, the easternmost reaches of the Bristol Channel, is at Court Hill and Kenn, near Clevedon, where erratic boulders and till are exposed (Hawkins and Kellaway, ; Gilbertson and Hawkins, ,b). While it is likely that ice did reach the Bristol area based on this evidence, there is no strong evidence for ice reaching further east into Wiltshire (Scourse, ) (Fig.…”

A synthesis of new publically available borehole and bathymetric data, combined with a wealth of other existing disparate data sources, reveals new insights into the Quaternary history of the Bristol Channel area. Sediment boreholes throughout the Bristol Channel confirm the area was glaciated in the Pleistocene. Till is present below marine deposits and, in some areas, is visible morphologically as submerged moraines. In the central and eastern Bristol Channel the submerged valley course of the palaeo‐Severn is very clear in new high‐resolution bathymetric surveys. This former river course and associated tributaries cross‐cut through glacial sediments in the Bristol Channel. At least three phases of glaciation are recorded in the Bristol Channel, one related to the southern limits of a Late Devensian Substage (∼Marine Isotope Stage (MIS) 2) Welsh Ice Cap which reached into Swansea Bay, an earlier Devensian (MIS 4–3) glaciation associated with Irish Sea ice, and another older glaciation that is associated with ice that filled the entire outer and central Bristol Channel. The age of the older Bristol Channel glaciation is still open, although it pre‐dates the Devensian (Late Pleistocene) and must date to the Middle Pleistocene. It is therefore evident that Pleistocene glacial and fluvial activity, combined with subsequent post‐glacial sea transgression, directly account for current morphometries of the Bristol Channel and Severn Estuary, and the current geography of the SW British Isles.

“…However, the Fremington till of Irish Sea origin (Mitchell, 1960;Stephens, 1966Stephens, , 1970Wood, 1974;Kidson and Wood, 1974) has been equated with earlier glaciations (originally Wolstonian but more recently Anglian) based upon its stratigraphic association with other dated deposits (Hawkins and Kellaway, 1971;Gilbertson and Hawkins, 1978;Andrews et al, 1984;Bowen et al, 1985;Bowen and Sykes, 1988). Although shell fragments from the Fremington deposits have yielded amino acid ratios indicative of a range of ages from early Pleistocene to late Devensian (Bowen, 1994), an Anglian age is preferred by Croot et al (1996).…”

This paper reviews the evidence presently available (as at December 2003) in an effort to stimulate further research on the last British Ice Sheet and promote a reconstruction of ice sheet behaviour based on glacial geology and geomorphology. The wide range of evidence that has been scrutinized for inclusion on the glacial map is assessed with respect to the variability of its quality and quantity and the existing controversies in ice sheet reconstructions. Landforms interpreted as being of unequivocal ice-marginal origin (moraines, ice-contact glacifluvial landforms and lateral meltwater channels) and till sheet margins are used in conjunction with available chronological control to locate former glacier and ice-sheet margins throughout the last glacial cycle. Subglacial landforms (drumlins, flutings and eskers) have been used to demarcate former flow patterns within the ice sheet. The compilation of evidence in a regional map is crucial to any future reconstructions of palaeo-ice sheet dynamics and will provide a clearer understanding of ice sheet configuration, ice divide migration and ice thickness and coverage for the British Ice Sheet as it evolved through the last glacial cycle.2

“…The significance of the term 'foundered strata' was explained by Hawkins & Kellaway (1971) as originally being a response to the cartographic requirement of indicating solid formational boundaries below landslip. The apparent impracticability of showing such boundaries with any confidence beneath highly disturbed valley slopes led to their representation as 'foundered strata,' symbolized by horizontal lines and a uniform colour.…”

In March 1984 the British Geological Survey commenced an environmental geological study of parts of west Wiltshire and south east Avon for the Department of the Environment. The objective of this study was to collect the available geological data relevant to the area, and to present them as a series of thematic maps accompanied by a descriptive report and a database/archive of the data used.The output is intended to be used by land-use planners. It is designed simultaneously to be understandable by people not trained in geology and yet to contain detailed information required by specialists concerned with the environment and its development. The 14 maps which were produced describe themes which include solid lithostratigraphy, drift deposits, the inferred distribution of Great Oolite Freestone, the inferred distribution of fuller's earth, groundwater, ground conditions in relation to groundwater, geotechnical properties of bedrock and superficial deposits, landslipped and cambered strata, distribution of slope angle, and mining.Although the task was primarily a desk study, it was found necessary to carry out a small amount of field survey to re-interpret the foundered strata to the north-west of Bath. This re-survey has been presented in a style consistent with the mapping of the rest of the study area. A fifteenth map showing the result Of the reinterpretation of the foundered strata was produced as a supplement to the main report.This paper describes the methods and the results of this study and comments on the implications of the technique for land-use planning.
