PHOTOS SUGGEST STONEHENGE A "GAPING OPEN" CIRCLE?

I read today that Stonehenge, may have been a complete circle.  At present, the ring is incomplete. Some British archaeologists have argued that was its original design.  Others have assumed that it was circular, but the stones were removed and used elsewhere ---a common occurrence in antiquity.

The discovery relating to its circularity, was made by a groundsman tasked with maintaining the lawn by watering the site.  This perceptive fellow noticed that during the recent (August 2014) drought, patches of brown were appearing in the normally verdant lawns. The effect was enhanced since the area where the circle was incomplete lay too far away from the short hosepipe he had for watering.  As this observant man made plans to irrigate the dry  and brown patches, he realized that these  seemed to be located in places where stones should have stood were the circle complete.  He brought in the professionals who immediately ordered aerial photos to be taken.

The Guardian published one of the pictures.  (The Guardian, Sept 1, 2014, Dry spell at Stonehenge reveals secret that has alluded archaeologists. By Steven Morris.) The dry spots do seem to indicate a curving line of patches which would crudely tend to complete the circle.

On closer examination, however, I observed something that reminded me of a feature I once encountered in studying post hole patterns of a house structure in the sub-soil at a prehistoric Native American site.  The post hole pattern in that case gaped away from the circular to provide an entrance way.  The pattern of brown patches at Stonehenge seem to suggest a similar type of pattern.  The patches on the bottom right of the published picture seem to fall away from (have a longer radius from the center than)  those on the left.  That "gape" were it actual, would have provided a wide and graceful entry point, perhaps adapted for ceremonial purposes.

Thus I suggest that Stonehenge may not have been a complete circle, but one with part of its outer stone erections arranged with a greater radius from the center to form an entranceway. The British archaeologists should investigate this "gaping circle" hypothesis .  Based only upon the revealing photos, I suspect that upon closer examination of the photos and further subsurface analysis they may well confirm this "open" pattern.
