What is it? Where is it?

Thanks. the latest image makes things a little clearer I think because the white rectangles are added by Google, right? That really threw me off. I originally thought they were real structures, but I don't think they are. My first thought after this was Four Corners but it isn't after checking maps because the Northern road doesn't been that way. Anyway, I'm sure Hamakua will help.
