a demonstration on how the GPR unit works.
In the spring of 2004,
we experimented with soil resistivity survey to learn whether this method
would add information about likely subsurface features.

The resistivity machine runs on grids that are 10 or 20 meters long,
pausing to take a reading every 0.25 meter on the grid.

geophysical surveys and soil core work resumes next year.
