This presentation examines some of the work being done to find extraterrestrial intelligence, including the search for exoplanets that may be able to harbor life.

Discussion of a publication about Herndon Bay and the paradigm shift that will occur with the recognition that the Carolina Bays were created by secondary impacts of glacier ice.

The term "Ghost Bays" was originally used by Prof. W. Prouty to refer to Carolina Bays that have been highly eroded by moving water and are almost undetectable.

Kaczorowski's 1977 thesis does not provide a reliable foundation for the hypothesis that the Carolina Bays are similar to oriented lakes and that they were created by eolian and lacustrine mechanisms.

Several objections have been raised against the Younger Dryas Impact Hypothesis. This presentation examines whether it is possible to build a physics-based model with the information that is available.

Studying geology and astronomy after retirement led to the publication of several books about the Carolina Bays and a peer-reviewed publication.

Examination of the geological traces left on a variety of terrains by the secondary impacts of ice boulders ejected by an extraterrestrial impact on the Laurentide Ice Sheet.

Discussion of the flooding associated with the meteorite impact 12,900 years ago. The story is complicated because there were several meltwater pulses at the end of the Ice Age.

A book published in 2006 proposed that a cosmic chain of events culminated in the extinction of the megafauna approximately 13,000 years ago. This book established what was later called the Younger Dryas Impact Hypothesis.

This presentation discusses the 31-kilometer impact crater beneath Hiawatha Glacier in northwest Greenland that may have formed at the onset of the Younger Dryas cooling event.
