What happens beneath Yellowstone is vast and varied. One of the most interesting geological phenomena found here is hydrothermal explosions. While they may not have a timetable like some of the iconic geysers, or the breathtaking colors of some pools, 2024’s sky-high event at Biscuit Basin put hydrothermal explosions on the map. Reading about this unpredictable encounter got me thinking: what are the underlying forces behind hydrothermal explosions? Is the caldera waking up? How are they studied? Luckily, our guest will explain all that and more!Joining us is Dr. Mike Poland, a research geophysicist and the current Scientist-in-Charge of the Yellowstone Volcano Observatory with the United States Geological Survey. His area of expertise is volcano geodesy, which emphasizes the surface deformation and gravity fields associated with volcanic activity, but he also knows a heck of a lot about hydrothermal explosions and other exciting geological activities in Yellowstone. He’ll also share a few of his favorite spots in the park to check out rock formations, thermal features, and beyond.Let’s dive in and learn more about why Yellowstone is a blast!The Greater Yellowstone Ecosystem is the land of 49+ Indigenous Tribes who maintain current and ancestral connections to the lands, waters, wildlife, plants, and more.Voices of Greater Yellowstone was created by the Greater Yellowstone Coalition, a conservation nonprofit dedicated to working with people to protect the lands, waters, and wildlife of the Greater Yellowstone Ecosystem, now and for future generations.> Listen on Apple Podcasts, Spotify, or wherever you get podcasts.> Join our Online Community and Receive Two FREE Stickers!> Donate to the Greater Yellowstone Coalition> Caldera Chronicles> Black Diamond Pool Explosion VideoPodcast Artwork > Rachel Dunlap ArtMusic >Redwood Trail by Audionautix is licensed under a Creative Commons Attribution license (https://creativecommons.org/licenses/...)Artist: http://audionautix.com/Thumbnail Photo > USGS/Joshua SellsSend us a note!Support the show
