Underneath Utah: Our 'Young' Volcanoes

CEDAR MOUNTAIN, Utah (ABC4 – Utah) Good 4 Utah is celebrating Utah’s diverse and unique geologic history this summer. Kylie Bearse and photographer Gus Seashore are traveling to Utah’s famous landmarks, and a few spots you may not have known about, to learn more about our state’s geology.

Utah has an incredibly rich volcanic history, but sometimes it isn't until you're standing on top of a volcano and you can see the flows of lava,  that you can really appreciate the impact volcanism has had on our state.

The Markagunt Plateau, on the backside of Cedar Breaks, showcases multiple volcanoes and lava flows.

‘There's several of them up here on Cedar Mountain. [It} has one of the most extensive volcanic fields in Utah, maybe hundreds of square miles,” said Lance Weaver, a Geologist with the Utah Geologic Survey.

Spendlove Knoll Is considered one of the more “recent’ parts of our geologic history.

“Recent geologically speaking,” said Weaver. “Most of these have erupted in the last million years. Some of them really recent, in the last two thousand years. It’s really the most recent part of Utah's history – volcanism.”

There are quite a few places across Utah where you can find expansive lava flows.

“Just to the west, there's actually large caldera complexes that are bigger than Yellowstone,” said Weaver.

The big question whenever we talk about volcanoes - Will it ever erupt again? Since this cinder cone is relatively young - it's a good possibility that one day we could see more eruptions.

“Volcanism is a really active part of geology, it's an interesting part of geology, and if you get to be there, like with Mount St. Helens, it's really exciting,” said Weaver.
