GPR transects in the western site perimeter survey, east of the road. The transects are 20 m long and have been surface normalized to account for the surface depression. The vertical axis represents two-way travel time of the radar energy, which is estimated to possess a velocity between 7.7-9.5 cm/sec in these soils (making the maximum penetration depth 1.5-1.9 m).
