Following on from yesterday. At https://phys.org/news/2021-11-vast-patches-glassy-chilean-ancient.html ... deposits of dark silicate dust are strewn across a 75 km long corridor in the Atacame desert of northern Chile, between the Andes on the east, and the coastal range on the west. New research says they were likely formed by the heat of a come [or comet fragment] exploding close to the surface. It has been provisionally dated to 12,000 years ago. The heat was so intense it turned the sandy soil into slabs of silicate glass.

At www.thunderbolts.info/wp/2021/08/20/the-shocking-truth/ ... Andrew Hall is a man with some interesting ideas on geology. His talks, at conference, are always well received, and the various offerings he dishes up to Thunderbolts. Some people think he is actually rewriting geological theory - which is untrue. He is offering some different ways to interpret some of the rocks of the world. Fred Hoyle, in one of his books, described the effects of lightning on mountain tops, and high ground.

At https://phys.org/news/2021-10-team-evidence-prehistoric-human-falkland.html ... a Univerisity of Maine led study has found evidence of humans in the Falkland Islands going back deep into the Holocene. In particular, between AD 150 and the 1400s, as well as in the 1700s. The latter corresponds with the arrival of European settlement but the former appears to indicate people from Patagonia were able to reach the Falklands by boat from roughly what we might describe as the Roman Warm Period until the outbreak of the Black Death pandemic in the 1400s.

[see also https://doi.org/10.1126/science.abf1015 and https://doi.org/10.1126/science.abf1396 ] ... the Juno spacecraft has peered deeper into the clouds on Jupiter and it seems the Great Red Spot storm track extends far beneath the top of the atmosphere. The storm seems to reach a depth of 500 km it has been calculated. The jet strems that make the bands of colour at the top of Jupiter's atmosphere on the other hand extend 3000 km downwards.
