the hole isnt a work of nature the japs had a base of operations on my land for quite some time.......there is even what looks like the actual command center in a man made cave in a waterfall close by my land with what appears to be a concrete table in it!!! havent really explored that cave its hard to reach but some of our local tribal friends have been in there and have described what they saw in there, after i dig out what i have i plan on exploring that area and a couple other places on the tribal land that i have permission to visit and survey!!! but anyway they dug out this hole perfectly and packed the sides of the clay earth smooth then poured concrete on top of whatever they buried. According to an eyewitness there is alot of gold buried here. But i am not telling the whole lucky story until i find something. the only thing i will say is that i just bought this land and before i purchased this land i had no idea that there was gold on it nor did/does the previous owner. The ex owner is a freind of my fiancee and sold us 30 hectars for the price of 10,000 u.s which is a very good price, because he had never used this land nor been to it before he sold it. The funny thing is that his father knew about the gold but died during the war.
