Here are some screenshots from a video of a waterfall adjacent to Maikwak Mountain in the remote Amazonian region of western Guyana. As you can see, there's a slight possibility the rock walls and surfaces depicted may be manmade.
Of course it could be naturally formed rock, but as you can see there are quite a number of completely flat surfaces and 90 degree angles which should be looked at by mainstream archaeologists up close.(I believe this is Tu-Mung Falls, not 100% sure, but there's other photos online).
The Amazon region has numerous ancient structures, remnants of ancient towns, shrouded by the jungle. So it wouldn't be surprising for large stone structures to have been built here in the past and remaining undiscovered.

Do you have more pictures and footage
Looks like natural to me. Sedimentary rock be like that.
