I believe there could be a discovery like this left... just not on land, but somehwere in the oceans, there might be something that just hasnt been seen by the right person yet.,(reply>), @SeanBZA 70-80%*,(reply>), 95% of the ocean floor is only there in a map as a rough model, depth only, with none of it ever being seen at any sort of resolution other than at the kilometre square level, from gravity maps. Even harbours have poor maps, really only thing they know is the depth of channels, and that there are no obstructions there, nothing really aside from that.
