Madisonville (WVLT) - Two crop circles in two years. It has residents in Monroe County scratching their heads wondering what or who is causing the circles in their hay fields. Wednesday night, they got some answers.

Very curious Madisonville residents fill a local cafe. They want answers to the mysterious crop circles in their county. This one turned up last summer, then this one last week.

"I wasn't sure if it was true or not curiosity getting the best of me," resident Mike Pilkey said.

Jeff Wilson is the director of International Crop Circle Research Association. Last year he investigated the crop circles off Rocky Springs Road.

He found higher-than-average levels of radiation and electromagnetic activity. The nodes of the wheat were also analyzed and found to show unnatural elongation, but he says last week's crop circles are a man made hoax--with a walking path to the circles and no radiation or irregular nodes.

"Either they use board as they stomp down the wheat as they go along or use garden roll where they flatten plants down," Wilson said.

Jeff says it's common after a non-man made crop circle appears to have copycats try to make another one similar in the same area, but he discourages it because farmers take a hit financially.

"Farmer's gong to lose several hundred dollars of wheat it's pretty extensive crop circle," Wilson said.

Johnnie Helms owns the 50 acre wheat field where the latest crop circle was found. She is upset about the recent vandalism on her property.

"I don't like it and if I find out who did it i'm going to prosecute em," Helms said.

So last week's circles are declared the work of a copy cat, but it still makes you wonder who made these circles last year. Jeff Wilson says it's very uncommon to have two authentic crop circles in one area.
