does the japanese buried their loots with sea sand?

[t_mcjames15]

we have found pile of logs, clam shells and stone shaped cement. we are close to 30ft and we located the clam shells at 22ft and the logs at 15ft and 20ft.. we only have the picture of the stones because we intentionally threw the clam shells away as our project had raised curiousness within our neighborhood. they were suspicious of our "WELL Project" but we successfully get rid of these gossipers eventually. here are the pictures of the stones..

can anyone pls interpret these?

your reply will be very helpful in our treasure hunting.. thank you in advance!

So did you find it? By now you should have. Those are positive signs of a deposit. The only problem are the traps. Maybe you can share to the community your knowledge on that project.
