UFO Trace - Landing Mark

Index Page

A disc-shaped object with dome was seem to light up valley as it landed one evening.
The witness returned the next day and discovered a circle of scorched grass about 10m in diameter.


A lot of holes around edge of disc like those of a turbine, and jet beams darted from the holes which burned the grass when the object departed.


Ball of slow-moving red light. Foul smelling mist. CE3 reported. Multiple witnesses. Found skid marks on the ground leading down a hill to an area where the grass was matted in a circle about fifteen feet in diameter. Greaselike residue on plants in the area.


Marie-L. Bourriot. Craft departed; small footprints found.


...leaving behing imprints on the ground from the wheels on its undercarriage.


Mme. Leboeuf. One being 3 ft. tall, diving suit, helmet, large eyes; flat circular craft; dog barked, being approached, witness fled; circle of crushed foliage found at site.

Raymond Romand. Two beings, squarish with legs; fiery ball hovered over meadow, light from barn reflected off being, child threw pebbles that struck it with metallic sound; 12-foot circle of flattened grass, imprints, at site"

Everett Clark. Four human-looking beings, unintelligible vocal sounds, entered cigar-shaped craft on ground as if "walking through glass," took off silently; elliptical imprint 5 ft. x 24 ft. found in grass.

At Socorro, New Mexico -- the site where Lonnie Zamora saw a UFO -- investigators found burn marks and impressions in the ground that indicated the presence of strange craft.

Lonnie Zamora. The investigators also examined what looked like landing marks found on the desert floor. In the middle of these marks was a burned area, apparently from the spacecraft's exhaust.


The craft landed in a nearby meadow. Test by professor Ernest Gehman and two DuPont engineers revealed a concentration of radiation at the landing site which spread over an area corresponding to the estimated size of the UFO.


James Flynn. Extensive physical trace evidence was found, including an area of burnt sawgrass 72 feet in diameter.

The Valensole UFO left behind a deep hole and other traces and affected the surrounding plant life.

Maurice Masse. An oval-shaped structure resting on four legs. In its wake the object left a deep hole and a moist area that soon hardened like concrete. Plants in the vicinity decayed, and analysis found a higher amount of calcium at the landing site than elsewhere. Laboratory study of the affected soil and plants confirmed the occurrence of an unusual event.


Patches of singed grass were found at the site.


Testimony of Brigadier General Arthur Exon commander of Wright-Patterson Air Force Base mentioning officers assigned to the Washington, D.C., area that would fly into Wright-Patterson on commercial flights and then deploy on military aircraft to investigate UFO sightings. A case in Arizona where the craft had touched down and left a burned area.

  These were Project Moon Dust teams engaging in the collection of UFO-related material.

George Pedley UFO nest encounter, Tully, Queensland, Australia (daylight close encounter with UFO take-off leaving physical evidence UFO nest).

Center for Physical Trace Research: Australia, 1966 - A well known case with witness George Pedley...A slightly elongated circular depression remained in the swamp grass, the area measured 32 feet long and 25 feet wide. The grass was flattened clockwise to the surface of the water, reeds had been uprooted from the mud below.


A resident of the women's dormitory at Hillsdale College reported a strange object in the sky. County Civil Defense director William E. Van Horn responded and confirmed that a bright glowing object was indeed bouncing across a nearby hollow and then became airborne. J. Allen Hynek was a scientific consultant to the Air Force Project Blue Book and a UFO-skeptic at that time. Hynek, who died in 1986, dismissed the Hillsdale sighting as "swamp gas". Within 2 weeks, however, he changed not only his opinion about the sighting, but also sides in the great UFO debate. Perhaps it was the comments of Van Horn's report that sparked his "conversion". Soil analysis showed that on the very spot where the "swamp gas" had touched down, radiation levels were higher than in the surrounding terrain. More significant still was the finding that the ground was also contaminated with Boron, the element used to slow nuclear chain reactions.



High strangeness report ivestigated by Dr. J. Allen Hynek and Ted R. Phillips.

Three 3- to 4-ft tall beings, light-colored clothing, helmets, moved around beneath cigar-shaped craft with windows; physical traces found at site.

On the site an area of scorched brush was found.



Almiro Martins De Freitas. At the spot where Almiro had encountered the object, concrete was fresh on the boulder precipice, and it had been raining heavily, but the concrete had suddenly hardened, and all around, there was a dry circle.

Glowing ring taken within minutes of the sighting photographed by Mr. Johnson.

Witness Ronald Johnson. Ronald and his parents then went to examine the place at which the object had been first seen. They were astonished to find a glowing ring on the ground, and some sort of glowing material on nearby trees.

The ring was still clearly visible thirty-two days later when examined by a UFO investigator named Ted Phillips, who specializes in physical-trace case.

RED FLAG: Jacques Vallee, claimed in his book Dimensions, a French biologist identified the white fibers in the soil as a fungus-like organism of the order Actinomycetales, whose growth can cause a circular pattern to form on the ground. In addition, this biologist, who asked not to be identified, stated that this fungus is often found growing with another fungus of the order Basidiomysetes, which may fluoresce under some conditions.

James G. R. Investigators subsequently found broken tree limbs, crushed foliage, and on some trees burned leaves as high as 35 feet above the ground. In the days ahead more leaves wilted and died. The UFO left imprints two feet deep in the hard ground.

The man reported the sighting to the police. A search of the fields conducted by the police and and the Belgium army turned up a giant circular area.


Their son went to the spot of the encounter the next day. He found, and videotaped, four circular ground traces in a rectangular shape about twenty-five by thirty feet. The grass in each of the circular marks was twisted and depressed. A fine, yellowish powder was found on the blades of grass.



Kelly Cahill. Inside that semicircle was a triangular formation of three points by 6 meters apart which corespond with the tripod configuration drawn by several eye witnesses.

John Auchettl - Physicist written transcript:


 The main data we got from the field analysis is chemical changes to the soil, three markings on the ground, that were approximately 75 centimeters in diameter, also we used a special magnetometer on the field itself and we discovered an unusual anomaly on the field that looked like a half moon facing toward the north. There was other things that came from the encounter, was that each of the girls espescially because the men seemed to be isolated from both of their cars but the girls indicated to us that they've been interfered with in some way. And one of the girls called Glinda who is a trained nurse, a registered nurse. She had markings on here which she went to a GEP and the GEP photographed them and consequence we had some very good evidence of a triangle under her naval and a mark in her let inner thigh and a mark on the base of her, down towards her ancle. So their was a lot of good evidence available.

Ted Phillips - Photographs of UFO Physical Trace Evidence

Reported physical evidence cases have also been studied by various private scientist and engineers. For example, researcher Ted Phillips, a protege of J. Allen Hynek at CUFOS, has studied 3200 so-called UFO trace evidence cases typically associated with alleged landings or close interactions. Such traces include such things as tree and foliage damage, vehicle damage, electromagnetic effects, radiation, various residues, footprints, and soil depression, burning, and dessication.
