Surface impacts and the mining crater shadow. While lateral impacts blast more directionally the more perpendicular type make ore distributions in a radial with larger veins of ore in crater walls or obstructions in their path. Very large impact can be disturbed by later impacts and tectonic drifts.
Column Basalt Mount Rainier, Washington USA - This is a sure sign there has been an earth crust breaking impact. It is a harmonic shock wave construct.
Carlsbad Caverns - This is a waveform signature. It is an off harmonic, a resonate wave not on a pure note.

The double crater is like a central uplift only more pronounced as a crater signature. Is it a harmonic? Yes.
Christina Reed Your specimen is an impactite. The surface designs are energy dissipation signatures. They often imprint in iron or quartz a dipolar simi conductor typology. The sand is from where it impacted now fused together from shock. So why the energy signatures? Impact shock waves can end with a microwave signature also the turbulent particles generate electric charge. The circles may be pelting of shock spheres but the shock/charge phenomena can also make circles. Look at this map and notice how the topo makes the two circle rings like big impacts do. Found Dinosaur Flats.

Two massive, rapid releases of carbon during the onset of the Palaeocene–Eocene thermal maximum
The Earth’s climate abruptly warmed by 5–8 °C during the Palaeocene–Eocene thermal maximum (PETM), about 55.5 million years ago1,2. This warming was associated with a massive addition of carbon to the ocean–atmosphere system, but estimates of the Earth system response to this perturbation are complicated by widely varying estimates of the duration of carbon release, which range from less than a year to tens of thousands of years. In addition the source of the carbon, and whether it was released as a single injection or in several pulses, remains the subject of debate2,3,4. Here we present a new high-resolution carbon isotope record from terrestrial deposits in the Bighorn Basin (Wyoming, USA) spanning the PETM, and interpret the record using a carbon-cycle box model of the ocean–atmosphere–biosphere system. Our record shows that the beginning of the PETM is characterized by not one but two distinct carbon release events, separated by a recovery to background values. To reproduce this pattern, our model requires two discrete pulses of carbon released directly to the atmosphere, at average rates exceeding 0.9 Pg C yr−1, with the first pulse lasting fewer than 2,000 years. We thus conclude that the PETM involved one or more reservoirs capable of repeated, catastrophic carbon release, and that rates of carbon release during the PETM were more similar to those associated with modern anthropogenic emissions5 than previously suggested3,4.

Interesting specimen. Impactite, suspect Powder River Basin Impact or larger impact. Cone in cone forms. Melt expansion nodule with surface mosaic. High energy and rapid formation. Orogeny: Chevron forms are not associated with volcanic mafic raised form small specimens. The specimen has a melt core matrix therefore the surface is an expansion mosaic. The surface is too complex for mud drying cracks nor would mud form a rock without a high energy event as it would just dissolve back to soil. Pottery kiln temperatures are around 2,200 F lava can provide this level of energy, but this specimen is a turn on turn off fast cycle energy made form which favors impact energy. Volcanic strewn fields are much smaller than impact. There are a few thousand volcanoes on Earth. Based on Mars which has over 600,000 impacts of a mile diameter or more and is roughly half earths size the Earth has more than a million impact craters. Why is the Powder River Basin an oval if it is an impact? Deformation or lateral impact or other? The Fort Union Formation is roughly circular however the multi state basin is continuous. The Montana Badlands has a high amount of impact ash indicating a very large earth impact. Complex stress surfaces are the physical result of an accretion body.

TeePee Canyon Agate, Custer County, SD USA - Polymorph crystals, high resonance impactite shock agate. The red balls pictured right side are impact spheres, a shock made particle. With high enough energy these spheres are overcoming the rejection pattern sequence and melting into a violet blend. This earth impact a type 3 exploding type is centered between Rapid City and Gillette Wyoming. It is a crater around 400 miles in diameter.
The red particles are in a banding sequence, an essential levitation as they are surfing the resonance. Particle levitation has been produced in laboratories with high resonance. The next step would be melting into a solid band as energy increases.
Overshock with iron. The thin triangles are vacancy high energy cones, very rare. The thinner the triangle the more energy was involved. It is a coning gassing void, a type of mosaic heat surface. It is intriguing that the left one skipped a section and then made an inversion of the cone as a disintegration form. The overall surface is a high shock metamorphic with cavitation and misted iron from the bolide iron plasma cloud. A rare and remarkable specimen.

They don't scratch glass, a steel nail does and leaves a powder behind. 3 are round. One is broken and inside are tiny pinkish and blackish crystaks and dirty Druzy quartz, I think. They feel chalky, but nothing comes off by handling.

This specimen is a dissertation of rejection patterning. A high shock type 2 impactite containing both impact material and impacting bolide material. It is a meta form and Splatterform with rejection patterns at two levels. The inclusions arrived from closer to the center of the impact as there rejection patterning is higher shock. The specimen while containing linear Constellationing as a rejection pattern also has some larger "false strata" or strata larger linear striation in the top left bits. This could be a larger shock wave imprinting (false strata) or sediment lines. The extreme indention of the inclusions indicate it was very hot and has isolated around these inclusions as a cooling differentiation mosaic. While it does have a small section in upper top right side that appears to be a shallow ablation surface the overall presentation is not a meteorite. As for specific impact orogeny only a very large earth impact could have made this specimen. Primary suspect crater would be the Navada Basin Crater. Large Ordovician Crater.

Interesting lil things..
Impactite, opal with cavitation and impact geometric. Few people have ever seen an impactite with cavitation much less an opal one and the hexagon cavitation is over the top. Carnelian surface of the cavitation indicates this cavitation was produced by the plasma bubbles of iron in hypersonic flight as ejected from crater. The opal indicates water was also present at the time of impact. Hexagon cavitation is produced by the bubbles surrounding pushing back when formed.

Impactites all, Perrie Crater. The Perrie Crater can be seen on the sand soil map of SD. While the glacier top modification has distorted the crater it is still evident. Your specimens have a compressed ash, nano burnt iron and crypto crystalline silica composition. The cubic specimens are a high heat mosaic where the whole body of the specimen is in a cooling cracking. The crypto crystalline chert (SiO2) specimen exhibits two energy signatures. The top marked 1 is a type of Turing Pattern (Alan Turing 1952). Turing patterns are a "rejection pattern sequence." A rejection pattern sequence is a state of energy and the response of dissimilar materials isolating. The second (2) is an energy signature, a coning fractal charged leaking attempting to ground or connect, caught in this incomplete state. It is not a harmonic like "shatter cones," but pure energy. The energy was created by the impact explosion turbulence of so much nano material. While not an electro magnetic pulse it is a state where high active charge would prohibit any electro magnetic wave from passing as this energy would become part of the diffused energy like chaff in WW2. Could this physics be made into a weapon or counter measure? Yes. It would make a good proposal for 6.1 Basic Science research. May 4, 2023

Type 2/3 subduction/Exploding crater. Big low angle impact from the northeast.
Surface topography can be difficult considering the limited knowledge of crater types and the one theory of tectonics. Notice the arc directly below the central uplift/retarc. Also consider that this is not a laboratory experiment. Impacting bolides are not uniform nor is the surface where they hit. The subduction can even cause a flare off as seen in the NW as the energy is expended deeper below ground. Also subsequent impacts will scar these large craters as large craters are earlier as shown between arrows.
.jpg)
Notice how the earthquake shows the rubble epicenter. As a NE subduction this shift is a reflection of the disturbed lower strata still trying to resolve stress. It is not plate boundaries. You can take two sheets of paper and never make a circular fault system by ramming them together. Aug. 1, 2023.

The mining map shows the same offset as the earthquake epicenter. The rubble also gets the exploded minerals from the bolide. You can also see two more possible craters in the southern edge of the state.

The Medicine Bow WY Crater. This is an angled impact from the west. Craters this large express a deeper signature on a gravity map therefore not a complete circle.
Big crater effect, shock bricking. I see this here in the Howell, TN crater and yes it appears to be man-made but will be found in the most obscure places. Here in the Howell crater, I first observed it in small creeks entering the Elk River not a place anyone ever built a wall. BTW in your location it is surrounded by impact ash calcium bentonite. This ash was once limestone but burnt and blasted outward. The physics of impact bricking goes like this. It is a sub type of "false strata." The lateral component is the shock wavelength imprinting in the resident strata or compressing the ash into shale. As a wave harmonic stalls at its crest that breaks the strata as an imprint. The vertical component of bricking is the materials inability to absorb this energy and it breaks to the weak lateral lines which is why these breaks are not a continuing linear to the next lateral line and are unevenly spaced. Your second picture also has impalement holes as explosion is a progressive process. The red surface is the plasma iron which falls as a mist and welds to surfaces, these are often the last effect in the forensic physics analysis of your location. Attached in the USGS gravity map for WY with the big Medicine Bow two craters the upper and smaller lower. Either one could have made your location but the high volume of ash indicates the larger, but this could be a two step process with the ash from the bigger impact and the compression and bricking from a later impact.

Shock agate/popcorn from the SD Retarc. Shock melt mosaic type surface which is bubbling a botryodial form (A botryoidal texture or mineral habit, is one in which the mineral has an external form composed of many rounded segments, named for the Ancient Greek βότρυς (bótrus), meaning "a bunch of grapes") The matrix is mixing much like mixing paint in a can. Other beautiful shock agates can be found in this area. So, you are asking what is a "Retarc?" A retarc is crater spelled backwards. These craters make only a central uplift as they explode too deeply for the traditional crater ring structure. Here is a nice picture of it attached.

Polymorphism, pseudo morphism, twinning, planar deformation features, resonate alignment - First the provenance of where found is an overlapping of more than one crater but one is enough. The attached picture shows one that broke the Earth's Crust, called a "Crusta Confractus (CC)." The joke in physics is the assumption of the simplest case. Explosion physics is chaos and multiple direction shock is normal. That explains the offset directions as you can see this when a water wave encounters a barrier and bounces back on the original wave. Another physics that is poorly understood is that polymorphism, pseudo morphism, twinning and resonate alignment are all the same impact physics phenomenon. They are just differing expressions of a common cause with resonate alignment being the overarching principle. See all the dots in your specimen. That is more important than is ever considered. These small particles are from the impact particle storm. If they are all the same size that is called the "common particle" which has been sorted with distance. It is also the tons of micro meteorites that fall by the ton each day on Earth. The particles align by attenuation to the shock resonance imprinting the wave lengths. As the particle dispersal in chaotic some lengths of the wave imprint go unprinted. I hope you don't mind if I add your specimen to my encyclopedia of impact phenomenon. Signal Peak AZ Crater.

The crater can be seen on the USGS magnetic and gravity maps. While the magnetic map shows the central core of the impact the Gravity map is much more interesting. The famous joke in physics is the assumption of simplest case but as you can see what happened is the density of the impacting bolide is not uniform making what resembles two impacts at the same time.

This is an impactite (large earth crater rock). The phenomena exhibited is an impalement. The chert matrix (a matrix is the dominant body of a rock) has been impaled by the quarts impact sphere/simi sphere as we do know if it broke at the time of origin or later. The quartz has a triangle which is a crystal pseudomorph as it was formed too quickly to complete the cubic structure. The radial lines called an eyelash effect are due to the impact of the quartz inclusion as the matrix was still pliable. The black is black iron oxide Fe3O4 which came from the iron ore in the impacting bolide/meteor. This can fall on impactite as a mist from the plasma impact core cloud and bond. The four-state crater dominates this area and could be the causal impact, but earth has over a million impact craters and each state an average of 2,000. Let's take a look at the four-state crater (attached). On this gravity anomaly map (Chegg Products & Services) you can see the dense gravity central uplift crater core and the surrounding blast material ring although broken up in density. On a surface topology map the crater is centered at the four-state intersection so we can determine the impact direction coming from the NE as gravity anomaly is a deep look at the earth's surface.

Impactite, from Idaho 3 Crater Confluence. This is called impact hieroglyphics. While the human brain is biased towards seeing human forms, etc., what is really interesting is the row of chain circles. That is not common. It is a repetitive resonance, like something you might see on an oscilloscope. Note the trace iron on top right side. That is from the meteor/bolide. The lower banding is a flow pattern as this was formed in a liquid state. The silica matrix may have once been sand. May 30, 2024.

The Western Four State Crater looks to have been a Carboniferous Period Event. It is a rather large crater to have occurred so late. Jan. 19,2024.
Impact shifting structure, White Pocket, AZ Peter Pallagi This is part of the Western Four State Crater. White Pocket is on the border upper central AZ. Explosion wave patterns - First the up down columns are sinusoidal and striated. This GPa is similar to striated Shatter Cones which occurs at the lower range (2 - 30) as the higher range loses it striation and melts together smooth. Banded striation - This indicates a resonate harmonic in which the minerals are attenuating at different harmonic frequencies i.e. silica versus iron. Crossing geometric patterning - A wave form grid is the overlapping of similar size wave lengths. In an explosion the shock bounces off and makes echo shock waves. Jan. 20, 2024.
Multiple shear breaks, iron particle surface inclusions. High heat mosaic, energized constellationing, granular crystal habit, a rejection pattern, indicating it was in an energy state.
Vectored sheer breaks while forming orogeny or later? Notice you have a mosaic crossing stich which indicates this all happened together.

San Raffel Wedge, Utah. So lets revisit Utah. Here is a nice picture showing the triangle points again as was shown above when asking where do the triangle points come from? Raft/Plate Tectonics cannot explain this. It is as simple as taking sheets of aluminum foil in you kitchen and ramming them together and see if you can make uniform triangle points in a row. You cannot. That is how theories fail. The triangle points are simple upward energy in excess of the moving earth a coning form like shatter cones. The alternating minerals are banding by shock attenuation either during this event or a previous one. So let's take another look at Utah with Topo map. Feb. 24, 2024. Photo by Rob Little.
The big western states four state crater goes through Utah from the SE, but the San Raffel Riff (shown as star on above map) is from a smaller crater. Now it does not matter if a crater is only partially present or was not round to start with. Just like with your aluminum foil experiment you will not be making arcs by raft/plate tectonics. Based on Mars the Earth has about 2,000 surface craters per state so this is not all of them.
Wiki overview. The San Rafael Swell is a large geologic feature located in south-central Utah, United States about 16 miles (26 km) west of Green River. The San Rafael Swell, measuring approximately 75 by 40 miles (121 by 64 km), consists of a giant dome-shaped anticline of sandstone, shale, and limestone that was pushed up during the Paleocene Laramide Orogeny 60–40 million years ago. Since that time, infrequent but powerful flash floods have eroded the sedimentary rocks into numerous valleys, canyons, gorges, mesas, buttes, and badlands.
Crater distortions. As you can see on other planets and our Moon crater become distorted by subsequent impacts. Also surfaces are not always flat and uniform nor are impacting meteor/bolides/protoplanets/comets/asteroids round. That is why I say all impacts are unique. Additionally angle of impact does affect crater shapes. Large or fast impacts can subduct the crust making what is thought to be raft/plate tectonics but is really impact tectonics. Feb. 24, 2024.
Meteorite or impactite - Flow lines. Notice how the top is just etched but the sides are linear. It even has an indention also etched. Tektites are an impact glass and this is a ferro silica. Not easy to etch. Having said that the physics of origin are the same, i.e. impact. So why would the etching be different on a meteorite versus an impactite? A meteorite has a limited energy to mark its surface and often the surface differs from its matrix like the fusion crust. This specimen appears have been hot all over but surface etched by a high velocity particle storm like in an impact. This storm was faster than earth entry which can vary from 10 to 30 miles per second. On the other hand impact ejecta can double its impact speed making the impactite travel up to 60 miles per second. Which would also be the speed of a particle storm. Was this from an Arizona or a California impact? The magnetic map of AZ shows a crater that appears to have hit from the west but encompasses the border area. See attached. March 5, 2024.

The right crater is similar to the Barringer Crater in AZ a square crater. The left crater is a crater "retarc," an uppie where the explosion happened deeper. It is also a slider from a lower angle impact. March 19, 2024.

But wait, that is not all it is a four crater county. What appears to be a slider is a small crater. Look how nicely the SW crater made and banded the coal. I wonder if it has diamonds?
And there they are. But now we can see the whole state and other bigger craters. March 19, 2024.
Clean Cavitation Impactite - Not common. Most impact cavitated impact specimens retain iron from the iron plasma. This appears to have once been limestone bedrock, now shock hardened dolomite. Random cavitation versus flow cavitation - Meteorites have flow cavitation as they are cavitated by directional entry into the Earth's atmosphere. Impact explosions are random chaos as seen on this specimen. Attached are a couple of small craters of NE Kansas. March 20, 2024.

Found this several years ago in Northeast Kansas. Can’t tell if it’s something like a very crudely made drill, or a naturally occurring Leaverite. It was, however, found in the immediate area of other easily identifiable artifacts, much better looking than this. I’m leaning towards the idea it was someone’s first attempt at flintknapping a tool lol.

NW New Mexico Crater Gravity Circle. April 30, 2024.
Thank you for posting this strata. It could be mined as decorative stone. Let me offer a few ideas based on forensic physics and impact tectonics. Sand pushed around and as sandstone into hills and even mountains needs a mechanism to be a solid and up so high. The slow pressure of sediments does not lend itself well to this terrain difficulty. Well then you have raft/plate tectonics, an interesting shadow theory like Plato's cave. You can easily disprove this theory with sheets of aluminum foil at your kitchen table. Push them together and they crinkle but do not make circles.
Next is the idea that toxic minerals condense out of earth seas. Chemical condensates or precipitates tend to be salts.
This is contrary to the continuation of fossils found in all of these time periods. It is an old theory dating back to the 1800's originally called "spring release" from some earth crack and later renamed Mississippi Valley Type (MVT). No such crack has ever been found to source this theory after more than a century.
Lateral flow and step cracking or bricking is a phenomenon common to impact. Shock of high magnitude makes matter liquid and presents with wavelength layered step banding cracks which as so powerful the cracks are joined vertically by the excess energy. Iron and cobalt are common to impacts and present as surface ores. They are from the impacting bolide.
The physics of this presentation are easier to explain with impact tectonics than with sedimentary raft theory. This stratum is from a big crater shown on the attached link it is large and takes up the NE state crossing over into South Dakota. May 3, 2024.

Geo-Note! This heavy-mineral sandstone outcrop is exposed near an unnamed tributary of Black Butte Creek in Sweetwater County. "Heavy" minerals like ilmenite and zircon are denser than quartz. Flowing water—in this case waves on a beach—sorted the sand grains by density and deposited the heavy minerals together.
Crater directional axis and wall deformation record. Note the fractal alignment. This is the angle of impact. Fractals tend to branch away from the energy source, hence a SE impact. These fractals form fractal cones a remarkable phenomena as a shatter cone writ large. The western wall has been deformed by a later big impact. May 3, 2024.

High states of impact shock melt. The first two pictures are of the same specimen. These boudin inclusions are melt droplets in a matrix. The wormy looking specimen is the same only more densely packed with scattering elongated droplets. The black and white specimen is an impact made agate but with low resonance.

The Hell Creek Formation Crater is much bigger than the circle shown above. It broke the Earth's crust (Crusta Confractus) and left that signature. In this view it appears to have come from the SE. Low angle (less than 45 degrees) and larger impacts release the explosion force on one side of the forming crater with a distinct higher energy level on the touch down side. So, that would be consistent with the impacting bolide coming from the NW May 25, 2024. A 250 mile crater, bigger than Chicxulub.

Hello again fellow rockhounds and crystal lovers!
The other day, I posted some of my "Payson Diamonds," which are double-terminated Quartz crystals found at Diamond Point near Payson, AZ. The ones I showed you were not my best finds from that location, they were the less perfect ones that I don't display.
This is one of my favorite finds from there. It's champagne-colored, double-terminated Quartz, with perfect points that are Amethyst. It has, what looks like, a flower, on one side. It's amazing from every angle! This one gets displayed in one of my acrylic wall shelves. I absolutely love it!
