Crop Circles in GM Crops?

A tractor prepares a field by turning over the cover crop into the soil in preparation for planting at Leafy Greens, in the Salinas Valley, California on Thursday, June 16, 2011. Leafy Greens grows row crops of lettuce, broccoli, cauliflower sweet peas and seed beans. He uses rotational crop plantings to control weeds and plant disease. When a plot of land is at rest, he plants a cover crop of barley and rye grass because the roots hold the topsoil reducing erosion of the soil. He is converting his irrigation system from conventional sprinklers to micro irrigation. Where one system produces runoff and erosion of the soil; the other has little or no erosion, less maintenance, easy harvest and less water is needed. When seasonal rains produce runoff, the silt that flows with it is caught in sediment ponds. The ponds have grass, bushes and trees to hold the structure and allow the silt to settle. Spillways lead to holding ponds and eventually the Salinas River, a tributary of the Monterey Bay National Marine Sanctuary. So far, because of its design and efficiency, no water has made it to the river. USDA Media by Lance Cheung.

Question by Dragoner: Crop Circles in GM Crops?
Do crop circles happen in GM crops as well as non-GM crops. Here in UK GM crops are not allowed, except in Uk.gov fields where the pollen wafts away on the wind to cover the entire countryside.
