| Lithological Description: |
The Ham Green Gravel Member comprises gravels, 3-4 m thick, with a surface lying about 30 m above the present River Avon. A basal lag with the remains of large mammals was reported at Victoria Pit, Twerton by Winwood (1889) and Davies and Fry (1929). The age is unclear, possibly being correlatable with MIS 12 according to Table 18 in Bowen (1999). |
