            "@value": "<p>The erstwhile Bowman’s Lodge Pit and Wansunt Pit were situated either side of Station Road, Dartford, on deposits mapped as belonging to the Orsett Heath/Boyn Hill terrace. They were worked for gravel from ~1900–1950, during which time they were subject to several detailed investigations (Chandler &amp; Leach 1912; Smith &amp; Dewey 1914; Tester 1951). The sequence at both can be summarised as ~15m of gravel (Dartford Heath Gravel: DHG) overlain by a variable depth of silt and clay (Wansunt Loam), reaching a maximum height of ~ 42m above Ordnance Datum (aOD). The Dartford sites thus lie at the same height and on the same terrace as the deposits at Swanscombe ~8km to the east, with which they can be directly correlated. A tributary channel recorded by Dewey (1959) beneath the DHG at Pearson’s Pit is cut to the same level as the Lower Gravel at Swanscombe and correlated with the Phase I deposits (Bridgland 1994). Fauna from the DHG includes interglacial mammalian taxa such as Palaeoloxodon antiquus, Cervus elaphas and Equus ferus (Chandler &amp; Leach 1912) and the distinctive ‘Rhenish’ molluscan suite, which appears in the Lower Thames between Hoxnian Pollen Zones IIIa-IIIb (White et al. 2013) and allows a firm correlation between the DHG and the Phase II Middle Gravel at Swanscombe. The Wansunt Loam is equivalent to the Upper Loams at Swanscombe, where it reaches ~40m aOD (Wenban-Smith et al. 2001), and is therefore correlated with a post-Hoxnian warm phase, i.e. MIS 11a.</p>\n\n<p>Few artefacts have been recovered from the body of the DHG, those that are present being similar to the Middle Gravel material from Swanscombe, but a significant, primary-context assemblage has been recovered from the surface of the DHG and within the Wansunt Loam (Tester 1951, 1975). These are assigned to Roe’s Group VI, subgroup C, with a high frequency of twisted ovates.</p>",
