The Ancient Island That Transformed Washington: A SciShow Field Trip #2

The video explores the geology of Olympic National Park, focusing on the presence of basalt despite the absence of volcanoes. It explains the story of Seletzia, a volcanic island that collided with North America 50 million years ago, leading to the basalt found in the region. The video discusses geological evidence and hypotheses about Seletzia's origin, including the role of the Yellowstone hotspot. The narrative highlights the importance of understanding geological history to appreciate the landscape.

What might happen to Celesia if it had been able to subduct under the North American plate?

Explain the significance of the Yellowstone hotspot in relation to the formation of Celesia.
