The Bruneau-Jarbidge volcanic field, also known as the Bruneau-Jarbidge eruptive center [1] is located in present-day southwest Idaho. The volcano erupted during the Miocene , between ten and twelve million years ago, spreading a thick blanket of ash in the Bruneau-Jarbidge event .
Other observable volcanic features in the plain include: the Menan Buttes, the Big Southern Butte, Craters of the Moon, the Wapi Lava Field and Hell's Half Acre. These calderas are in an area called Island Park that is known for beautiful forests, large springs, clear streams, waterfalls, lakes, ponds, marshes, wildlife, and fishing.
The Mesa Falls Tuff is a tuff formation produced by the Mesa Falls eruption that formed the Henry's Fork Caldera that is located in Idaho west of Yellowstone National Park. [1] It is the second most recent caldera forming eruption from the Yellowstone hotspot and ejected of 280 km 3 (67 cu mi) of material.

“The frequency of eruptions over the past 15,000 years and the age of the youngest eruption indicate that future outpourings of lava in this area are expected and anticipated.” | Opinion
In the NBC miniseries, 10.5: Apocalypse, this mountain is an extinct volcano that erupts with devastating force. An avalanche of hot gases and ash cascaded down the mountain and buried everything, including the mountain's ski areas, and the towns of Sun Valley, Ketchum, and Hailey.

The Henry's Fork Caldera in eastern Idaho is a caldera located in an area known as Island Park, west of Yellowstone National Park. The caldera was formed by an eruption 1.3 million years ago of the Yellowstone hotspot.
This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest known eruptions in the Yellowstone hotspot's history. This eruption, 2.1 million years ago, is the third most recent large caldera-forming eruption from the Yellowstone hotspot. It was followed by the Mesa Falls Tuff and the Lava Creek Tuff eruptions.
