On top of the ridge!! Antonio Zamora 2023-05-16 | In South Carolina, there are Carolina Bays on top of a ridge that is 40 to 50 meters higher than the surrounding area. This presents an interesting puzzle for geologists. Why are these Carolina Bays at an elevation of 200 meters above sea level and 200 kilometers away from the Atlantic coast? This video also introduces a method for estimating when all the Carolina Bays will disappear due to erosion.Scientific Psychic® is an educational web site dedicated to the exploration of the human mind with the objective of encouraging critical thinking, a healthy life style and improved communication skills.scientificpsychic.comThe Neglected Carolina Bays: Ubiquitous Geological Evidence of a Cataclysm.Amazon: amzn.to/3uTRDsZ A.

SpaceX debris makes mini Carolina Bays Antonio Zamora 2023-04-26 | The SpaceX Starship prototype blasted off the launchpad at 8:33 a.m. in the morning of April 20, 2023. The powerful blast of the engines produced a dust cloud that covered Port Isabel, Texas, in grime about six miles away, and it also broke some concrete structures at the launch pad. Large concrete boulders were ejected in ballistic trajectories that produced impact craters on the soft ground in a mechanism similar to the one that formed the Carolina Bays.

Crackling Ice Antonio Zamora 2023-02-13 | #shorts When ice comes out of the freezer, it is typically well below the freezing point of water at 0°C. When we place the ice in water at room temperature, the relative warmth of the liquid makes the outer layers of the ice start to contract, while their cold inner layers remain unchanged. This creates tension between the layers, and the ice pieces break up producing a crackling sound.

Sparrow makes Carolina Bays Antonio Zamora 2023-02-02 | The origin of the Carolina Bays has spawned many diverse ideas about their formation, including that they originated as fish nests. The elliptical geomorphology of the bays indicates that they originated as inclined conical cavities, but this video offers the tongue-in-cheek idea that sparrows taking sand baths created the bays.The Neglected Carolina Bays: Ubiquitous Geological Evidence of a Cataclysm.Amazon: amzn.to/3uTRDsZ Python programs for least squares fitting of ellipses.github.com/citpeks/Carolina-Bays-least-squares-ellipse-fitting
Missoula floods were caused by volcanism Antonio Zamora 2023-01-29 | At the end of the Last Glacial Maximum, about 20,000 years ago, much of Earth's northern hemisphere was covered by vast ice sheets. Huge ice sheets covered much of Canada and the northern United States with a mass of ice that was nearly 4 kilometers thick in some places. The rapid melting of the ice sheets has been enigmatic because the periods of melting and splintering into the sea occurred at the coldest times of the last Ice Age. In recent years, there has been increasing evidence suggesting that volcanism was involved in the deglaciation of the Cordilleran ice sheet.The Neglected Carolina Bays: Ubiquitous Geological Evidence of a Cataclysm.Amazon: amzn.to/3uTRDsZ
Slush balls and slurry cannot make Carolina Bays Antonio Zamora 2023-01-17 | The idea that the Carolina Bays were produced as a result of an extraterrestrial impact on the Laurentide Ice Sheet by the Great Lakes region has many supporters, but there are diverse proposals for the mechanisms that created the bays including oblique secondary impacts by ice boulders, impacts by slush balls, and deposition of sheets of ejecta slurry with imbedded steam bubbles.

The Glacier Ice Impact Hypothesis Antonio Zamora 2022-10-25 | The Glacier Ice Impact Hypothesis proposes four mechanisms for the creation of the Carolina Bays and the Nebraska Rainwater Basins. First, one or more extraterrestrial impacts on the Laurentide Ice Sheet by the Great Lakes ejected pieces of glacier ice in ballistic trajectories. The secondary impacts produced seismic vibrations that liquefied unconsolidated soil. The oblique impacts of glacier ice on viscous ground created inclined conical cavities. And finally, the inclined conical cavities, also called penetration funnels, became shallow elliptical basins by viscous relaxation. Carolina Bay Survey.

Deniers and ignorers of elliptical geomorphology Antonio Zamora 2022-08-13 | The study of the Carolina Bays has become a battle ground between proponents of the eolian and lacustrine hypothesis, which claims that wind and water created the bays by gradualistic processes over a long period of time, and by proponents of various impact hypotheses, which claim that oblique impacts by projectiles of some sort created the Carolina Bays. A crucial part of the debate involves the elliptical geometry of the bays and their radial orientation toward a convergence point by the Great Lakes. The question of the geometry of the Carolina Bays can finally be settled by fitting them with ellipses using the least squares method.Carolina Bay Survey.
