JACKSON HOLE, WYO – Geologists of Jackson Hole has opened its regular Lunchtime Presentation to the general public. Today’s presentation will include a look at the Bighorn Basin.
“The Glaciers didn’t make it there: The environmental history of the Bighorn Basin” will be presented by Tom Minckley, University of Wyoming, Department of Geography.
The late-Quaternary record of glacial-interglacial environments in Wyoming is largely known from the last glacial period to present. Prior to 21,000 years ago, mountain lakes, where most of the Quaternary history of Wyoming is derived, were covered in glaciers and so history begins with their retreat.
However, caves near the base of the mountain ranges have been collecting pollen and other environmental detritus below glacial limits for millennia. These deposits provide insight into the late-Quaternary landscapes of Wyoming’s basins during the last glacial period.
Wednesday, April 18, The Senior Center, 830 East Hansen, talk will begin at 12:15, be there between 11:45-12:00 to sign up and get your lunch, $4 for those over 60 years old and $8 for those not yet 60.
