Too many great pix in this one !
JDDavis ; Your entry would make a great poster .
A couple of notes on my entry . Taken in 2003 or thereabouts at a lodge located around 100km up the Rio Napo from Puerto Francisco de Orellana in the Ecuadorean Amazon drainage . About 4 hrs. in a big metal cargo canoe , hike through the forest and then a trip via dugout canoe across the lake .It's a black water lake which might give the impression of depth . As for treasures , only ones I saw were caiman and piranhas
