Extraordinary Evidence and Inexplicable Ignorance: Bunch (2012) and The Bos (2013)

Bunch  Boslough It is telling to read competing journal articles regarding the Younger Dryas Boundary Event. For example below is the recent paper from The Bos, et al., and below that a publication from the YDB team the year before. (I was added as an author to that one based on some field work I did years before starting this blog). There are a number of interesting observations that…

3D Space Navigator and Carolina Bay LiDAR Data from Cintos Research: A Match Made In Heaven

  Eye Candy Earlier this week I purchased a wonderful device, the 3D Space Navigator Mouse from 3D Connexion. I am giving this cool tool Two Tusks Up and encourage any reader who works with 3D or Google Earth to purchase one post-haste. This sturdy little brick of a mouse has a foating head which provides complete control in three dimensional environments. It simply revolutionizes your…

Separated at Birth? Worldwide Dragon Myths and Meteor T(r)ails

  What’s up? From Hermann Burchard: George, here is  a simple model to explain the vapor trail’s observed symmetry: Partial cloudlets each side, North & South, have almost identical ones opposite. 1.  The Bos’ blowtorch momentum sims and video blow-ups from Steve Garcia’s posts indicate that the explosive ablations shoot debris ahead in the direction…

Linked?: Andrew Cooper on Feb 15 Asteroid and Russian Meteor

Cooper? Debunked: Not to be taken seriously. The first thing I noticed was a schoolboy blunder in  celestial mechanics:  you don’t add velocities in the way that he did, you add energies, that’s to say the squares of the velocities.  If an asteroid with an asymptotic approach speed of 5.6 km/s is going to hit Earth its  impact speed (prior to air resistance) would be  12.5…

The Song of Ullikummi: Grondine unpacks Bronze Age myth revealing Courty Impact Event

Two posts ago the Tusk provided some desperately needed oxygen to Marie-Agnes Courty’s work concluding the collapse of the Akkadian Empire in Mesopotamia around 2000 BC was the result of cosmic bombardment — not a volcano. Like the skeptics of the YDB group, Courty’s critics have long sought to bury the living, while shooing the rest of us along to better known subjects. Like…

Younger Dryas Event in California

One of the most intense debates in the paleosciences in recent years has focused on the question of whether or not a cosmic impact (comet) approximately 12,900 years ago caused both the Younger Dryas climatic oscillation and the disappearance of Pleistocene megaauna in North America. Since it was frst advanced in print by Firestone et al. (2007), the Younger Dryas Boundary (YDB) impact…
