Wah Wah Springs Caldera

A summer storm hits Wah Wah Valley and the Wah Wah Mountains, in May 2009

Wah Wah Springs Caldera is a supervolcanic eruption remnant discovered in 2013 in Utah. It released 5,500 to 5,900 cubic kilometres (1,300 to 1,400 cu mi) of tephra, as the Wah Wah Springs Tuff, about 30.06 million years ago in the early Oligocene. It is the largest of the Indian Peak-Caliente Caldera Complex, and includes flows over 500 m (1,640 feet) thick at the most. It is considered one of the largest single explosive eruptions known in Earth's history, and the second most energetic event to have occurred on Earth since the asteroid impact at the end of the Cretaceous period.[1][2]
