bro, i just read your post right now.
#1 seems there's a burried treasure. it could be in the cemetery or in the mangrove. i have seen 'lapida' like cement. well, the one i have seen was taken under sea water. it's interesting but i didn't try explore it. i know somewhere under lapida could be the burried treasure. or if alone, it could be a reference in order to locate the hidden treasure and i use L-rod detection to locate it.
#2 i think there is a tunnel in referrence to the stone, but be careful, some of it are laden with bombs. it is true that some bombs are still active and the batteries connected therein, has not yet discharged through the years. some mechanical detonations of such bombs are not rusted and intact. they used heavy greasing and oil to keep through the years.
#3 triangle - signifies gold treasure deposite, the knife of any kind is a pointer. if that marker is displace, just remember where it was taken.
let's find it out when you get here. let's just synchronize our time so that we can have the best plan of recovery with all best effort and resources we could employ for a success.
me, here, i am just up to exploration and studying, and planning what to do with my finds and analysis. i could start a project once i got the financing. and i hope that if could have my share when i work with you partnering in your project, i could start myself also.
thanks for the call this morning.
by the way, if you can, try find a good hi-technology detector/locator (not expensive but effective and easy to use and transport) that could be good also, not as substitute for my L-rod but to compliment. since what i got is only good for detecting gold descrimanately, more, it could not detect deepness wherein i use probing rods that is inserted in the ground locally known as 'sounder'. another is i have to depend on any marker i could decode in order to know details including deepness or traps.
i believe using all possible means... decoding, L-rods, hi-tech detector, probing, common sense, human and equipment resource, timing and planning plus faith and blessing of our God = success!
God bless you. please tell me when you could be in surigao and i will get in there. i think i could spend 3 days to a week with you... it will depend, i will just arrange our schedule.
