Y Chromosome Bottleneck Part IIAntonio Zamora2024-10-18 | Y Chromosome Bottleneck Part IIOn top of the ridge!!Antonio Zamora2023-05-16 | 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.

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.Nebraska Duck BasinsAntonio Zamora2023-04-17 | This presentation discusses the Nebraska Rainwater Basins that have the same elliptical geomorphology as the Carolina Bays, but which are located at an elevation of about 516 meters above sea level.

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.

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.

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.
