Figure 37: Single profile running north–south through Grid 6 at x=24m. The slope highlighted in Figure 35 runs between approximately x=9 (top) and x=13 (bottom) (marked). Note that the lack of topographic correction has the effect of seemingly detecting pronounced strata that run uphill towards the surface in this area, when in fact the stratigraphy is probably closer to horizontal, with the effect caused by the converse running of the antenna downhill and therefore closer (in terms of response time) to the sub-surface cause of the reflection. The position of the surface reflection visible at c. 9-13m corresponds to the gateway area off the fortress and may represent a flat area dug into the slope, similar to open areas in other gateways. The profile demonstrates the various areas of disturbance The time-slices (Figure 38) show that below c.
