Geologists of Jackson Hole's video: A Geologic Tour of the Jackson Hole Area

Presented by John Hebberger (Jr.), Geologists of Jackson Hole. Northwestern Wyoming and Jackson Hole in par9cular is one of the most beau9ful places on earth, with millions of visitors from across the globe traveling to enjoy it each year. What most do not recognize is that ALL of what one sees and wonders at is a result of more than 2.7 billion years of geologic events and geologic history. This “tour” of that geologic history will provide the audience with a basis to see, understand, and much be]er appreciate what draws so many visitors. Our area is a result of and evidence can be seen of: 1)) The earliest known “Himalayan Style” con9nental collision event; 2)) The break-up of the super con9nent that existed BEFORE the Pangea super con9nent; 3)) 500 million years of Wyoming’s existence at & near sea level; 4)) The con9nental scale compressional event that formed nearly ALL of Wyoming’s towering mountains & deep basins; 5)) A major volcanic event that today we see evidence of with the Absaroka Mountains; 6)) The advent of the Yellowstone volcano which migrated from the ID-NV-OR states’ borders to its present loca9on just north of Jackson Hole; 7)) Onset of the con9nental scale the extensional event which formed the American West’s “Basin & Range” province, and which is forming the Teton Range and Jackson Hole today; 8)) Major glacial episodes, from alpine style valley glaciers to a quasi-con9nental style of the ice sheet that en9rely filled Jackson Hole. Also discussed will be cutting-edge research pertaining to the Teton Fault, which might explain why the fault seems to currently be “locked” (inac9ve). This is something that is important to all of us as residents, and to our millions of annual visitors. A place like no other on earth, the audience will be able to appreciate it much more as a result of this presenta9on. September
