EERIE photos have shown a ring scorched into the ground where a family claimed to have watched a UFO land and knock down a tree.

On an episode of the History Channel’s series, The Proof Is Out There, witnesses and experts examined a possible UFO incident in Kansas in 1971.

On November 2, 1971, in Delphos, Kansas, Ron Johnson was working on his family farm when he saw a mushroom-shaped spacecraft.

Johnson, who was 16 at the time, ran to tell his parents and they returned to see the craft floating away.

But when they took a closer look at the ground near where the craft was, they noticed an eight-foot-wide ring.

The ring had a white crust around the edge and appeared to be glowing.

Harlan Enlow was a sheriff at the time and was one of the first officials to arrive at the scene.

“It was an eye-opening surprise,” Enlow told History.

“Here’s this white, dry ring, looks like a big donut, sitting in the middle of a mud field.”

Enlow said officials took photographs and soil samples at the scene.

Ron’s mother, Erma, told Enlow that when she touched the white crust, her fingers instantly went numb.

In addition to the Johnsons, two other eyewitnesses shared what they observed – including a tree falling.

The eyewitness reports led Enlow to believe something happened in that field.

“I am 100% convinced that an incident happened and what the family told us was credible,” he told History.

Experts and analysts have studied the

One expert told history that the white ring could’ve been ash.

Another expert, Dr. Bob Anderson, said that the glowing could come from an interaction between groundwater and bacteria.

Anderson also said that Erma Johnson’s burning could’ve been caused by acid in the soil.

But the investigation remains an unexplained phenomenon.
