Impact Craters

“Enigmas and Controversy in Science: Examples from Madagascar and Russian Lakes.” with Dallas Abbott (16 Apr 2016)

“Enigmas and Controversy in Science:
Examples from Madagascar and Russian Lakes.”

with Dallas Abbott

  

Originally presented 16 Apr 2016

 

Dallas Abbott has shared her studies of impact craters around the world at E2C Workshops for more than a decade, and we are please to welcome her back for a description of the Summer 2015 field studies of the surface features found in the area of Lake Smerdyachee, Russia. This workshop provides an excellent example of the objectives embodied in the  NGSS “Nature of Science”–Science is a continuous process of discovery. Dallas and colleagues have also gained interesting insights about unusual features on Madagascar. These chevrons may provide clues to gargantuan tsunamis from an asteroid impact 10,000 years ago.

Dallas’ previous E2C program on Lake Smerdyachee: “How Did Those Rocks Get Up There? Exploring Lake Smerdyachee, Russia” (April 2015).
