About The Yellowstone Hotspot
In Search of Ancient Yellowstone: How the Yellowstone
Hotspot Crafted the Pacific Northwest's Landscapes
With Ellen Bishop, PhD, Geologist, Photographer and
Writer
About the Lecture
The Yellowstone hotspot powers one of the world's most
explosive volcanoes. Today, it steams restively in Wyoming. But 60
million years ago, it erupted as seamounts off Oregon's coast.
The story of North American's collision and interaction with
the Yellowstone hotspot is one of geology's developing paradigms. Yellowstone
crafted much of the Northwest's landscapes. It created Oregon and
Washington's coast ranges, including the Olympic Mountains. In Washington, it
melted the crust beneath the North Cascades and uplifted the Okanogan and
Kettle Ranges. In Oregon the Yellowstone hotspot produced explosive volcanic
features including Smith Rock and the Owyhees. The Yellowstone hotspot also produced
all of the Columbia River basalts and much, much more enroute to creating our
nation's first national park.
Is today's Yellowstone poised to erupt again soon? And will
we repeat the scenario of colliding with a seamount and ridge someday?
This photography-rich talk will introduce you to the Yellowstone
hotspot's past, present, and possible future, and the astonishing landscapes
it's created.
