Results
of the GPR survey of an earthlodge. The 40 GPR profiles were time sliced. The
earthlodge floor was found at about 18 nS (TWTT), or about 90 cm below surface.
GPR reveals the floor as a circular region about 10-11 m in diameter, a shape
expected from the likely late dates of the occupation. The GPR data parallel
many of the magnetic anomalies. The slice shown averages the amplitudes through
20 nS.
