Magnetic survey of the Geophysics building, north lawn.
> Contour map shows residual magnetic field strength,
after removing the effects of the building.
> Line graphs are profiles of residual field strength along
survey lines.
> Dashed lines show a portion of one surveyed line.
> Hedge and front walk are at the left (south) edge of
plots.
