AdvisoryIf you arrived here by any means other than from the Index of Impacts, it is suggested that you
start at the Introduction to gain an understanding of what follows.

National Park is a huge volcanic caldron that sees millions of visitors
each year. It is full of hot springs and geysers and is being
constantly monitored for underground magma flows. It appears to have been made by a
hard deep penetrating asteroid which created a hole in the Earth, which allows water to seep in, get heated, then be
blown back out again. The
actual strike point is at the south western part of the park, such that
the asteroid came in from the southwest at a steep angle. This accounts for the raised
in the northern part of the impact site.|
The asteroid was probably large, dense and very fast moving to account for the high surrounding mountains and the relatively small crater. Rather than blowing material in all directions to make a ring of hills or mountains, it put a hole in the crust of the Earth like a bullet. This type of impact would create sharp and severe shock waves deep in the Earth that could crack the outer crust for great distances, while leaving relatively minimal surface marks. Compare this to the Navajo Impact. While the surface markings are relatively minimal, there are still impact created concentric shock wave rings out to 2325 miles (3800 km) in radius and possible beyond.
This impact is notable for the likely hood that it caused the crack in the Earth which accounts for many of the volcanoes of the Cascade Mountains. The next larger shock wave circle aligns precisely with the San Andres Fault in California, from which frequent earthquakes occur. Another larger one aligns with the southeastern coast of Texas. These are shown below.
What we are looking for with the circles below are geographical features that closely align with the circle. These features were caused by the circular seismic shock wave created by the impact.
impact came in from the south southwest as depicted by the
arrow. This meteor probably was very
dense and traveling at tremendous speeds. It punched a hole in the Earth
and formed the crater, circled in yellow. The surrounding
mountains were raised and the interior
area was left relatively low with lakes and hills.|
The white circle highlighting the seismic wave ring is shown at 140 miles radius. The various geographical alignments are shown just to the inside of the circle. The seismic waves do not have the same center as the crater. The center of impact is where the meteor first hit. The center of the crater is the center of the ejected matter. Another example of this can be seen at the Barringer Crater.
This ring does not appear to be as uniform as other shock wave rings, and a study of the rivers and other phenomena in this area indicates that this is actually a shatter pattern from the impact. A seismic wave ring aligns the geography in arcs which are noted easily, and align closely with the circle. This area however, while the rivers follow the circle, they are broken in straighter lines.
The difference here is that the Earth was shattered, similar to what you would find if you threw a rock into the window of a car, as opposed to the rolling concentric circles like the ripples from the rock thrown into the still pond. This would be consistent with a high velocity hard rock impact.
The above image is expandable to 2365 x 2057 pixels. The straight yellow lines follow the various land forms around the impact site in an attempt to simplify the area geography. This shatter pattern surrounds the center of impact and expands outward from there.
It appears that the small mountain to the east was originally part of the impact rim, as depicted here. These are the Bighorn Mountains.
The original impact that formed Yellowstone, raised the mountains to the north, and east (depicted by the irregular white marking). Then another meteor came in from a very low angle from the northwest (the large long arrow), and hit about at the base of the eastern rim, pushing that section of the rim to its' present position, as shown by the numerous small arrows. The meteor then skidded and plowed the Earth, forming the 'V' to make the present formation. The parallel markings on the land on each side of the large arrows attest to this.
The images below describe the major shock wave alignments for this impact, there are many others. The images are generally 1366 pixels wide but shown at 800 pixels to accommodate various view screens. (Ctrl and +/- to change size)
At 40 miles radius from the center of impact, a seismic circle presents itself. The way these seismic circles contour the land is definitive evidence of a meteor impact.
