Significant information may still be available at the site. If any samples were taken of material before the local sediment was disturbed, those samples would be very useful in any analysis. Also, photographs may be useful in reconstructing the depositional circum- stance in which the money materials were located.

In any case, investigation of the geologic circumstances of the money materials may yield the information as listed above.
