Re: [HOT] Strange object
Diamonds (or other gems) seem unlikely, we are too far from volcanic lava fields (diamonds and gems are formed in the Earth mantle and require hard rocks). Gold extraction is more likely (and the various holes around are probably old artisanal gold mines in the deposits of the river). The structure built on the river is more industrial and benefits from the continuous flow of muds, and is certainly more productive without needing digging. 2018-04-15 15:55 GMT+02:00 Henning Bolz : > @Blake: I meant the artificial, "technical"structure in the river, next to > the island (about 60-70 meters long). > @Philippe: you are right, gold or diamonds could be an explanation > > Many thanks > Henning > > > > The structure with tubes at tip of the the islet of the river looks like > some installation to filter muds in water and extract gold. > > 2018-04-15 14:31 GMT+02:00 Blake Girardot HOT/OSM < > blake.girar...@hotosm.org>: >> >> Hi Henning, >> >> I am not clear on what the object is you are looking at? >> >> Do you mean the water pools and pits along the south bank of that >> river?

Re: [HOT] Strange object
@Blake: I meant the artificial, "technical"structure in the river, next to the island (about 60-70 meters long). @Philippe: you are right, gold or diamonds could be an explanation Many thanks Henning The structure with tubes at tip of the the islet of the river looks like some installation to filter muds in water and extract gold. 2018-04-15 14:31 GMT+02:00 Blake Girardot HOT/OSM: Hi Henning, I am not clear on what the object is you are looking at? Do you mean the water pools and pits along the south bank of that river? If you mean those, if I had to guess, it looks like artisan mining to me. One active area and a few small older pits. But that is just my guess, I will be interested to find out what the local knowledge is about it. But that would be my first guess. Next would be agriculture of some sort, maybe.

Re: [HOT] Strange object
Hi Henning, I am not clear on what the object is you are looking at? Do you mean the water pools and pits along the south bank of that river? If you mean those, if I had to guess, it looks like artisan mining to me. One active area and a few small older pits. But that is just my guess, I will be interested to find out what the local knowledge is about it. But that would be my first guess. Next would be agriculture of some sort, maybe.

[HOT] Strange object
Hello HOT list, while working on task #2881, i found this strange object on Bing.
