I must commend you on your acute powers of observation.
This is indeed a very strange stone object.
Yes. Why the pinholes along the top and side rim?
Why the extrusion and rebated topside?
Why the central channel?
And, most curiously, why an incomplete circular hole?
Could this hole have been drilled? Isn't a drill, circular? It must have been made by some other method. But what?
And what is its purpose? A drainage hole? Hardly. A simple hole would have sufficed. There is something unexplained here.
What do you think original elevation above sea level was?
The fact that Lake Titicaca contains fish ( most native fish now extinct due to introduced species) would indicate access to the sea, unless a new version of evolution of fish at high altitudes can be proven. So, at 12600 feet above sea level, either, the fish swam up somehow to a landlocked lake, or, the fish were in the sealevel "lake" which was elevated thus trapping the fish.
So, to answer your question, my money is on a geologic uplift. Maybe, some stone workers went along for the ride. Ride 'em cowboy! And a lot of stuff came crashing down. After all, there are seashells on Mt Everest.
Which could mean that any area of land not uplifted could be far under the sea. But the sceptics say that Mu is a myth. I was in Sumatra before and after the 2004 tsunami. One side of islands went down and the other side went up. A tectonic uplift doesn't always happen purely vertically. It can occur at an angle.
But that hole. Fascinating!
