Re: D. B. Cooper
Dear Sir:
This letter is written in observation of recent events publicized in the newspapers regarding the discovery of money materials along the Columbia River in Southwestern Washington.
The newspaper accounts of this discovery did not indicate that any further investigation was being done regarding the geologic factors in which the materials were found. [REDACTED] it occurred to me that there may be abundant information available that might not ordinarily be pursued in this type of investigation. Accordingly, the following suggestions are offered for your consider- ation:
1. Sediment trapped within the material and surrounding material may provide clues as to the source areas from which the sand and material were transported from.
2. The sediment material may provide a clue as to other likely areas along the Columbia where additional materials might be deposited.
3. Analysis of the local stratagraphy and sedimentology may give an indication of the date that the materials were deposited at the location of discovery.

4. Analysis of the abrasion characteristics of the material itself, that is the money bundle, may suggest the distance traveled and thereby give additional clues as to the source from which the material was derived.

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. If not, the next time a discovery takes place, care should be taken to acquire the geologic information from the site before excavation takes place. In any case, investigation of the geologic circumstances of the money materials may yield the information as listed above.
