Sharing the Fascinating Ice Age Floods Story Since 1995
On 07 Oct 2024 the Puget Lobe Chapter will have Dr. Karin Lehnigk, Postdoctoral Researcher at Georgia Tech, who has studied the Channel Scablands in Eastern Washington by performing cosmogenic nuclide exposure dating on Missoula flood transported-boulders to determine what path they took at different points in time. It will be a very informative lecture with new information. Think Mars and Himalayan Mountains.
Cosmogenic nuclide dating is a method used to estimate the age of rock exposure at the Earth’s surface. It relies on the interactions between cosmic rays and nuclides in glacially transported boulders or eroded bedrock. By measuring nuclide concentrations, scientists can determine the age of landforms ranging from a few hundred years to tens of millions of years. It looks like a crust or rind on surface of the sample when you cut or break a sample open. (Micrsosoft Bing)
