Opinion needed on aerial photo

[Tommi]

Hi Guys n Girls

Just wanting to see what others think of this photo, I located it close to an area where I'm doing some world war two relic hunting and I thought its of interest.
Please note the the two circles on the football field, close by their is suppose to be tunnels and bunkers a few hundred feet away.

My question is: what are the circles?

Check the center of the circle for a stand pipe. Looks like maybe watering the grass with a large rainbird type sprayer.

they are crop circles,UFO's made them.

I'm probably wrong but it looks like the pic was taken by a hot air balloon with another one close by and those are balloon shadows. Swizzle

Not judging by the shadows of the building and utility poles. I'd go with irrigation.

I think your right, it would make perfect sense, the football feild would need constant watering and up keep, most logical explanation is 2 sprinklers working the field, the wet grass and damp soil would be a different colour to the dry counter part.

Hi,

At first blush the irrigator theory looks good but, I'm troubled. Two issues bother me 1) they are both *very* circular with precise edges and 2) the spacing between them doesn't suggest regular spacing and the absence of others in this image makes me wonder. Not that I have a better answer.

You mentioned that this was a football field. Is it literally or was that a figure of speech? Do you have any history as to what might have been on that site earlier? What is the diameter of the circles? Can you think of a structure that is common in the area (now or before) that was round with that size (silo, storage tank?).

I can think of two reasons for the grass being greener than the surrounding 1) more water (as mentioned) but, remember this could be due to irrigation or a difference in the soil composition such that it retains water better than the soil around it. 2) more nutrients (e.g. nitrogen). The later leads me back to the silo idea. Are they ever built without a solid pad under them? Seems unlikely but, if so, seepage from the contents would have an effect.

Hope that helps. If not, I fall back on the idea that those are two really big privy holes!!!!

Something else occurred to me. Possibly a pair of underground structures (for lack of a better word) that either retain water or nutrients.

Grasping at straws.

Hi Jim,

The picture is of a soccer field, the size of one of the circles would be approx 50feet, the feild is located on a downward slope, with the northern end raised to maintain a flat surface (i thought digging into the slope would archive a better result) and it then falls away to a creek.

no wood or other materials are located on the field, no information has been found on what was there in the past.

close by is an ex ww2 intellengence base, were a secret bunker was located under one of the buildings

A couple of things:

First, where is the field? The US? The UK?

Second, a story... back in the sixties on an US airbase in Germany a WWII bunker was accidently discovered under a softball field. A tractor actually fell into part of a tunnel. In short order, the tunnel was traced to a maintenance bunker (lots of aircraft parts, a machine shop, etc.). It was formerly a Luftwaffe base. The interesting part? One of the uprights supporting the backstop turned out to be a ventilation pipe for the bunker!

To me, the circles look odd - probably more like a sprinkler system of something - although I suppose they could be underground storage (fuel or the like).
