The rain the previous afternoon had heralded more of the same overnight and it was difficult to negotiate the 1.5km. track that gives vehicular access to the site, even in low gear in a Landrover. As we approached the site we saw that two of the volunteers had made it to site on time despite the conditions; we viewed the partially underwater trenches with some element of irritation. With rain continuing we sheltered from the worst of weather and started the day with a cuppa. The rain gave way to lighter rain and gusty showers, which served to replace any water in the trenches that evaporated due to the high winds. Rather than damage the fragile and clay rich deposits in the trenches it was decided to start the auger survey designed to try and characterise the nature of the fort ditch and see whether we could see any evidence of the construction of the rampart and any buried land-surfaces (Figure 4). The augering went slowly but by the end of the day we had run two auger transects across the upstanding section of the rampart and the ditch; in some locations stone prevented the auger from reaching the probable full depth and the very wet conditions meant that the samples frequently slipped out of the auger as it was removed from the ground. The auger survey indicates that we might expect the ditch to be between 1.6m and 1.8m deep.
