Excavation Unit 3 superimposed over GPR
In this GPR Slice image, made by Brian Damiata, hard reflectors from the Ground Penetrating Radar (GPR) survey are shown in yellow and red. In this GPR- slice, blue areas did not return any energy. This slice is from about 90 cm below the ground surface. The location of the hard reflectors (red and yellow) suggest that the stone wall excavated in EU3 probably continues to the southeast. EU3 is the excavation with the overhead image superimposed. If you look closely, you can see a row of stones in the east. You can see more of EU3 in a previous blog post. The red lines in the jpg are our best estimate as to the location of structures in the 1874 map, also described in a previous blog post.
