Today, we'd like to take you back. Way back.

To a time, 10,000 years ago, when volcanoes could spit their fire without delaying one Icelandic flight.

And more specifically, to one volcano. In Utah. That over time settled down, and now happens to be flooded with water. Warm water. We think you see where we're going with this: scuba.

Welcome to Homestead Crater, an old volcanic crater filled with warm water that's perfect for scuba diving, open now in Utah.
