I was fascinated when I stumbled across circular features along the Nile Delta near Alexandria, Egypt over Memorial weekend. The features appear to be some type of agricultural attempt and seem to be prevalent within the marshland regions of the Nile Delta. Many of the circular features are aligned in rows and what's even more peculiar is the size and alignment of these circular areas in relationship to the areas seen off the coast of Florida, North Carolina, in the Bahamas, Nassau, Cuba and in the Modoc National Forest in California; they all seem to be similar in size, alignment and placement near marshland regions.
There seems to be an obvious visual connection between all the image studies that I've been accumulating at the SD site. Why would similar features be seen in 10-20 feet of water off the Florida Keys and in the Bahamas?

What's great about the NASA WorldWind images is most are free to the public and are considered 'Public Domain' and can be used for commercial purposes. Thank you NASA!
