What I'm asking is geography. Is the spot Eric says is the money find location the same as where the feds put a stake in the ground?
I can 100% guarantee that the money find spot I identified in January 2019, the same spot I'm referring to today, is completely accurate.
The important things to reference are the small gravel road, the angle road (no longer in existence), the property line, and other physical features in the distance including access roads, the retention pond, and some of the Fazio buildings. Plus, the FBI creating a grid in the sand in 20-foot intervals provides a solid scale.
Also, going to the site and becoming familiar with it from all angles was critically important. Once I did that I could finally see how everything fit together. I can say that I probably know Tena Bar better than anyone at this point as far as it relates to the money find. I have spent a lot of hours there over several trips combing over the area from the ground, from the river by boat, even by helicopter.
Again, 45.718551, -122.759407 is 100% accurate, likely within 5-10 feet.
Knowing the flood history of the area is important too. Of note, beginning in June 1950--about the time the Fazio's purchased the property--up to February of 1980 when the money was found, the money find spot--in 1980 terms--was underwater seven times. Only two of these times occurred between the skyjacking in 1971 and 1980. In other words, there were five other times when the spot was underwater between June 1950 and June 1972.
But, there's a catch.
Dredge spoils very early on did have an impact on the spot. More to the point, the beach had formerly eroded quite a bit before being replenished by spoils. Therefore, the spot was also underwater in July 1968--3 1/2 years before the skyjacking--even though the river wasn't particularly high.
Also of note, after the June 1974 flood event which put the money find spot underwater, it was not underwater again for another 21 1/2 years until November of 1995.
