I can see anything of note at those coordinates. (That video clip talked about geometric shapes, something that looked like a ziggurat?) But if you go to, for instance, 84 21 N 137 45 E, you'll see some (can't miss) interesting formations, black, at the base of a very long, arched ridge; if you zoom in on the ridge, you'll see geometric forms on the entire length - something like a Grecian border (or tire treads). It's got to just be the way some things photograph that close up. But thanks for this post, fishyculture. You've introduced me to google Mars. It's fascinating.
