Meeting and Talks: "Still the Crater of Doom" and "Double Shot Observations"

At the Warren Astronomical Society's Cranbrook meetings, we spend the first hour or so of the meeting on club business and observing reports, then have two presentations, one short and one full-length.

The main presentation at our meeting at Cranbrook on March 3rd will be “Still the Crater of Doom” by Cranbrook's own John Zawiskie. He will critically review the historical development of the asteroid impact theory for the extinction of non-avian dinosaurs, including past controversies regarding the timing of the mass extinction and the impact that formed the massive Chicxulub crater in the Gulf of Mexico. John’s presentation will be highlighted by his own field photography of the strata in the Raton Basin in Colorado and New Mexico.

John is Cranbrook's Curator of Earth and Life Sciences and both a geologist and a paleontologist.

Chuck Dezelah will present the short talk, "Double Shot: Observing Two Objects at Once." He will help you get the most bang for your observing time. Why look at one object when you can see two?


If you would like to present either a short talk (10-15 minutes) or a full-length talk (45-60 minutes) at a future meeting, please email Dale Partin at [masked].

    Very informative,learned something about geology and how to read the layers of rock formations and the great powers that impact meteors possess..the double shot observations were very interesting as well,may have to turn my attention from the planets to more of the double shots in the future...good crowd.....
