| Lithological Description: |
Limestone-rich gravels forming the First Terrace of the River Windrush in the Vale of Bourton. The gravels extend beneath the alluvium. Channel-filling silts beneath cryoturbated gravels have yielded molluscs and pollen indicative of cold interstadial conditions (Gilbertson in Roe, 1976; Brown et al., 1980) and woolly mammoth has been recorded from several sites (O'Neil and Shotton, 1974; Briggs in Roe, 1976; Briggs et al., 1985, p. 32; Brown et al., 1980). |
