Deserts

MJ Harper has proposed a new theory on the formation of deserts - which is novel if nothing else. You can buy a video from Amazon - 'The Distribution of Deserts, a New Teory' by MJ Harper. There are lots of videos on deserts on www.youtube.com but these are mostly mainstream - Harper is a novel theory. Deserts, surprisingly occur at all kinds of latitudes so there might be something in what he says. Evaporation of the oceans and mountain formations (with a rain shadow on one side) are favourtite explanations but Harper has something else - plant respiration.

Canadian Pleistocene fossils

I'm not sure if this was sent in by somebody at the contact email address or I picked it up when reading something at a web site but at www.thecanadianencyclopedia.ca/en/article/quaternary-vertebrate-fossils/ ... we have a wonderful resource as this concerns the Pleistocene fauna of North America. The Canadian Shield is virtually fossil free - even geology free as it has been wiped clean of everything down to the Pre-Cambrian base as a result of the ice sheet during the Late Glacial Maximum, and outwash as a result of meltwaters.

The devil's hole

   Old Nick gets about as we have a Devil's Hole and a Devil's Punchbowl over here in the UK. At http://archaeologynewsnetwork.blogspot.co.uk/2015/12/a-climatological-tr... ... we have Devil's Hole in Nevada, situated on the edge of Death Valley in the Amargosa Desert and yet the narrow crack in the rock, above, leads down towards an underground water reservoir.

Andes Uplift

At http://phys.org/print369561139.html ... an interesting study of a massive volcanic field in the Andes that reveals a surprising amount of uplift in a short time scale, as much as 6 feet in the last 8 years. Apparently, this has occurred many times over the last 10,000 years of the Holocene.

Skye dinosaur footprints

The Times, December 2nd 2015, has a report on the discovery of dinosaur footprints on the island of Skye, which is situated off the west coast of Scotland and is renowned for its scenery (and its excessive rainfall). In the Jurassic the boundaries between land and ocean were somewhat different to what they are today.

lots of teeth

One for the grandchildren. Lots of teeth. Crocodiles and Dinosaurs (go to http://archaeologynewsnetwork.blogspot.co.uk/2015/12/fossil-hunters-unea...).

flood events

Flooding events are surprisingly common. There are surprising amounts of water in northern Britain at the moment (heavy and persistent rain swelling rivers)and as an example the link says the 2004 Indian Ocean tsunami killed more people in just 2 hours than the ongoing conflict in Syria has managed in 4 years. That is something to think about. Flooding events, in the present and in the past, have been severe and caused trauma and great loss of life. Take the drowning of the southern North Sea basin.

rivers in the Sahara

Gary sent in this link. At www.nature.com/ncomms/2015/151110/ncomms9751/full/ncomms9751.html ... and for double the effect see www.dailymail.co.uk/sciencetech/article-3312097/Lost-sands-time-Hidden-a... ... we learn that not so long ago, in the grand scheme of geological history, in the Late Quaternary, the Sahara had a network of freshwater lakes, rivers and streams, clearly fed by water falling out of the sky.

crack in the hills

this crack in the ground suddenly appeared in the foothills of the Bighorn Mountains in Wyoming. How did it come about? Nobody is saying for sure but a spokesman commented, it just goes to show how quickly some geological events can occur.
