The excavation at Bull Creek, Oklahoma, shows the paleosol — ancient buried soil; the dark black layer in the side of the cliff — that formed during the Younger Dryas. – UCSB
More recently, another group of earth scientists, including UCSB’s Alexander Simms and alumna Hanna Alexander, re-examined the [...]

Did a 6th Century Comet Bring Global Famine?
Evidence from tree rings and ice cores suggest that parts of Europe, Asia and North America saw protracted cooling in the 530′s, which has been linked to drought and famine. Some scientists hypothesize [...]
Annelies Van Hoesel (Dr. Van Hoesel yet?) recently published an overview of Younger Dryas Boundary Hypothesis in Quaternary Science Reviews. I hear at least one of the YDB authors found it terribly biased against the impact. But it seems to me that she is implicitly admitting that the many obituaries of the YDB impact have [...]

The always smug but relatively well informed Paul Heinrich had a post on the Meteorite-list serve today disputing the cosmic origin of circular features identified by Hermann Burchard [...]
