Looking at Area 51 with Google Satellite Maps

Followed the instructions written in Stevens Journal and had a good look at Area 51 using Google maps. Dont know what these shapes are supposed to be further up in the Map from Area 51. Could they be Crop circle training areas, just joking but I still havn't any ideas as to what they are. You? For some unknown reason you cannot zoom in as close as Steven could!

If you navigate down you will eventually come across Area 51. ...mr g
