Vesuvius

Sediments in the Bay of Naples have been explored and have revealed how the eruption of Vesuvius affected water supply and sewage/drainage systems - see http://phys.org/print382693782.html

Interestingly, a similar setback was seen to have occurred in the 5th century AD as a result of natural disasters and invasions of Italy. This led to a decline in maintenance.

Petrified Forest

At www.dailymail.co.uk/sciencetech/article-3593219/North-sea-reveals-7-000-... ... we have another tract of ancient forest revealed off the eastern coast of Britain - once joined to the continent (in this instance woodland stretched from NE England to Denmark). It seems it dates back 7000 years ago when it was covered in sand (a major storm event perhaps). It has been revealed as the tides have apparently washed away the sand that had covered it for so long. Again, another storm event perhaps.

Antarctic fossils

Over a ton (in weight) of fossils has been gathered in Antarctica by a team of scientists. They include marine creatures, dinosaurs, and birds (see www.smithsonianmag.com/smart-news/fossil-hunters-uncover-17-million-year...

At http://phys.org/print382814609.html ... giant bird fossils from Antarctica have been recorded by the Argentines. The shape of their wings allowed them to glide and cruise over large distances, like a sort of prehistoric albatross.

Earth's surface periodically moves up and down

This is a hot potato in some ways as it has been found the Earth's mantle flows and causes the crust to periodically move up and down. This observation was fine and dandy in a uniformitarian or gradualist timescale but it seems it may occur much more often than previously allowed - and the big question is how often that might be.

sand dunes

Louis Hissink on sand dunes - provoked by Gary Gilligan's recent guest post. At https://malagabay.wordpress.com/2016/05/03/louis-hissink-sand-dunes/ .... we learn he was a geologist working in the deserts of western and central Australia. He was tasked with counting sand dunes in order to navigate (prior to GPS) so he got to learn a lot about them - and to realise the dunes were extraordinarily stationary. Unshifting. Just as well I suppose if you are going to count the sand dunes in order to know where in the desert you might be.

Sand and Gary

Gary Gilligan has an interesting article on sand at https://malagabay.wordpress.com/2016/04/26/guest-post-by-gary-gilligan/ ... the purity of sand seems to belie the standard explanation. The amount of sand seems to defy the geological mainstream theory. How is sand transported to create vast dunes - and then we have something like this ....

Guy Berthault

Gary Gilligan sent in an interesting link - www.increasinglearning.com/blog/stratigraphy ... and see also www.youtube.com/watch?v=okJzgEZbdVg ... The former is a young Creationist web site but it seems that Berthault himself was not so inclined - see www.noanswersingenesis.org.au/berthault_is_yec_henke.htm .. where in response to a post he turns round and says he is not a Creationist. However, this view appears to have spread around mainstream and he is usually criticised on the basis his article is popular on Creationist web sites.

Earth Wobbles

At https://tallbloke.wordpress.com/2016/04/09/nasa-study-solves-two-mysteri... ... and at www.yahoo.com/news/nasa-global-warming-now-changing-earth-wobbles-180545... ... which in The Independent newspaper becomes a headline about global warming responsible for causing the spin axis of the earth to wobble (and no wonder that newspaper is not a viable business any longer and is ceasing a print edition).

Loess again

A few weeks ago we had an article that associated loess formations with water - a river cutting a channel through the Tibetan Plateau and carrying downstream debris from the eroded rock in that part of the world. This was contrary to normal mainstream thinking in regard to loess formation. The consensus view is that loess is formed by wind as the erosion agent. Not water. It was therefore a surprise to find an article based on field research that actually stated water erosion had caused at least one loess formation in China.

drumlins

Drumlin hills, shaped like upturned boats, are an Ice Age land form, well known in geology. However, the use of satellite images and LiDAR (ground penetrating radar from aircraft flying over regions of interest) has shown up the surface of our planet in great detail - and is springing surprises. Drumlins are often found in clusters, sometimes in their hundreds and thousands (mainly in Canada although drumlins also occur in Europe, even as far south as Ireland). They are thought to be footprints of the Ice Ages.
