It was only discovered by the identification of shatter cones near its centre.

Long shatter cones have been discovered in the southwestern part of the bay.

Shatter cones can range in size from microscopic to several meters.

Other than the original shatter cones found on the perimeter, there is little visible evidence of the structure.

He championed the use of shatter cones as evidence for ancient impact structures.

Moderately developed shatter cones add to the impact signature.

Coesite and shatter cones are found in the uplift near its center.

Many shatter cones, rock formations that form under the extreme pressures of impact, have been found around the lake.

The center of the crater contains some of the finest shatter cones in the world.

The recent discovery of shatter cones and microscopic shock effects is reliable evidence for an impact origin.

Telltale shatter cones were discovered in the bed of the nearby Vaal River.

Shatter cones, which are chevron-shaped impressions in rocks.

Shock features such as shatter cones are largely overgrown by vegetation or covered by the lake.

Subsequent research revealed definitive evidence for this hypothesis, including the presence of shatter cones and shocked quartz.

Shatter cones, a rock shattering pattern naturally formed only during impact events, are found in abundance in the area.

Field studies of these geological structures found a lack of identifiable shatter cones at both structures.

Knox strata in the central uplift are raised 350 m above their normal position and locally contain shatter cones.

Planar deformation features, diaplectic glass, melt rocks, and shatter cones have been identified.

Evidences of impact origin include shatter cones, impact breccias, and shocked quartz.

Later an amateur geologist Jarmo Moilanen discovered also shatter cones within the impact structure.

Instead, the striations, which were previously reported shatter cones, are identified as ventifacts created by wind erosion in sandstones.

The impact origin of this topographic feature was first proposed in the 1960s, the strongest evidence coming from the abundance of shatter cones.
