Illinoi, Indiana & Ohio Impact Craters
Canton Crater
Springfield Crater
Healed Impact Craters disturbed by fracking the shale an impact ash layer. By this disturbance the crater has to resolve again the impact crater. As the crater walls are a bunch of rubble and often can be seen as karst areas like the Chicxulub karst crater wall circle the rubble must reform itself.

Vugs with direction - This is a type of cindering but unlike the typical cinder it has a direction flow. Silica perhaps some trace calcium and iron. This was instant made from the large NW Central Illinois Impact Crater.
SE portion of Hamilton County, OH. This is the Silurian Impact Extinction Event Crater Floor with the ash pile up. Shock agates also found here.
This is a shock made impactite or some strange old concrete bubble. The matrix is a small particle composition which is blast pulverized material in the large bolide impact. It was a plasma when hit by a projectile causing a bubble bulge. This type of example is rare and I would consider valuable. Specimen collected in North Central Ohio River by: Ty Woody Johnson
Coning flow directionality with heat mosaic and shock residual waveforms. The matrix also has the nano iron from the impacting bolide as well as the granular particle matrix which is a pulverized impact material. It is heavy because it is a shock metamorphic may or may not have a tempering clink when struck probably not as it is the wrong acoustic shape.

Found in Central Illinois. This is petrified wood right? I love the detail in it, pictures don't do justice but it is a bit glittery looking and the veins on the back side and side appear to have crystals. What do you all think?
Chasing multiple harmonics, a relic from the Canton Crater. Impact sludge/silt shock hardened. It has harmonic:
shock wave impressions
circles
cones
granular particle circles
Holmes county, near Millersburg, Ohio. Found in a Creek. Observation: gravel approximately three to four feet below ground level.

Limestone Impact Sphere - Hard metamorphic range shock limestone with cooling mosaic cracks, fractal to septarian in layers which caused delamination. The coal was pushed up by the impact blast an organic material compression to the crater edge area. Limestone impact spheres are part of the center of the impact as it blast out the deep limestone layers and makes them liquid to form drops like hailstones. There are two major craters in Illinois, top and bottom.

The cracks are crystal/silver and shiny. Weighs about 3-5lbs. Found in Illinois
Impactite, flange forming sphere with high rotation and polymorphic iron crystal, core evaporation. As these impact ejecta relics can travel great distances and you are at the confluence of some big and small craters I do not know the crater source.

Any help with ID? Looks like petrified wood on one side and dookie on the other

Mega Clast/Impact Sphere, Huron, Ohio. Reformed limestone blast melted into round shape and ejected from a crater, most suspect is the Canton Crater.

Trying to find out what these are any help is appreciated
Slag or impact splatterform? If it is slag it will have some provenance of dumping or an industrial site near. I rather think it is a splatterform, quartz olivine melt. It also has a round bead present as in more melt type attachment.

Found these 2.stones today any ideas ?.. northern Ohio border area
Impactite, sine wave propagation. Melt in crevasses. Sine wave or triangle wave is what makes "shatter cones." This is an edge effect. Waves are energy in motion. In the center of an Earth Impact is chaos of shock waves. Waves however will overtake each other with distance and finally settle down to something like this. Your location is at the edge of two large craters 100 mile plus type.

Not sure about this one. Central Illinois
Impact breccia. Crude impact cement binder matrix. Impact makes ash a nano particle used in early cement. The specimen also has iron which is from the impacting bolide. The blast bits breccia are impact scatter. The Illinois Basin is an old impact crater complete with wiping event unconformity. Nov. 12, 2023.

Hi friends! Any insight into what this is?
Google wasn't much help, found in southern Illinois USA
Round Impactite Spheroid, Peoria, IL mid-state crater. Nov. 24, 2023.

12 inch diameter VERY round rock found in kickapoo creek in peoria IL. Is this just considered a nodule? Very heavy. Not flaky and no visible layering. Not shiny like hematite. It has a few bumps here and there. Ideas on formation and composition quite welcome.
Cojoined Impact Spheres - this occurs when the impact explosion blast material is in close proximity. Nov. 24, 2023.

Found in kickapoo creek in peoria Illinois. Looks like two rocks smashed together. It looks this way all around. Kind of looks melted but I'm guessing it is not. Any thoughts on what it might be called (besides weird rock) NOT magnetic.
Another look at Ohio Impact Craters.
Shawnee National Forest, this is iron splatter in sandstone from a big earth impact. The swirl pattern is not organized like impact spheres or boxwork. Jan. 9, 2024.
Hiking with Shawn.
Expansion boxwork forming, this is still not an organized type. Jan. 9, 2024. Hiking with Shawn.
Circles is a more organized form. Resonance attenuation is the likely mechanism. Jan. 9, 2024. Shawnee National Forest, Hiking with Shawn.
Intrusion wedge with harmonics including the sign wave "Tiger's Eye" type higher energy form. Jan. 9, 2024. Shawnee National Forest, Hiking with Shawn.
Oblate impact sphere with ridge. Ridge specimens are not that common. Most of central Indiana is taken up by a big crater complex. Impact spheres are liquified droplets ejected in the up splash of these larger impacts. The Barringer Crater in AZ only made fragment shards it takes a bigger impact to make impact spheres. The surface appears to have a coating of black iron oxide. Really big impacts make a plasma sphere like H bombs and this mist rains down coating the specimens or as they pass through it.

Any idea what kind of rock this is? Found in Central Indiana
Blast Crevassing. See the fractal flow patterns, that is an energy signature. April 30, 2024.

Rock House in Hocking Hills State Park, Ohio
Crater basin shown above where Hocking Hills State Park is located. April 30, 2024.
Shatter cones and variants. The stream has excavated down to the "shock floor." The pink is the impact iron mist that bond to impactites (a plasma late stage fallout.) Coning is a shock wave form set up as a sine wave, however this shock floor has variants with concave cones and cross striations. While the NW and SW state has some big old craters as shown on the geology anomaly mapping the central state is radioactive. Like meteorites the large earth impacts vary in meteor/bolide minerals. Even though later geological events alter the original crater like a glacier flow these minerals are embedded throughout the original crater area. You can still see this large crater on the uranium map. June 25, 2024.
Found a stream full of Cone-in-cone Formations today!! Columbus, Ohio
