Secret Places on Google Earth

If you haven’t seen Google Earth yet, go ahead and download and install it here:

After you are done, put these coordinates in the search box (on top left):

1-
50° 0’38.20″N 110° 6’48.32″W

This one is really cool but it looks like it’s random.

2-
19°56’58.08″S 69°38’2.25″W
(Zoom in a little bit)

Now, this one is not random, it was made by someone, some say Mayans but remember, they couldn’t fly so I think making something like this that only someone in the air can see would be their last thought… Correct me if I’m wrong, I can’t find anything about this on the internet.
Honestly, it looks like an alien to me
