"In southern Utah, deposits from this single eruption are 13,000 feet thick," said Eric Christiansen, the lead author for the BYU study. "Imagine the devastation - it would have been catastrophic to anything living within hundreds of miles."
Dinosaurs were already extinct during this time period, but what many people don't know is that 25-30 million years ago, North America was home to rhinos, camels, tortoises and even palm trees. Evidence of the ancient flora and fauna was preserved by volcanic deposits.

When I read about this kind of stuff I think how easy it would be to interpret it from a worldwide flood perspective. The Bible says that the waters from underneath broke through and caused massive geyser-like formations, it wasn't all just rain. The Earth's crust actually broke up, I imagine it was very traumatic. I think the Genesis flood explains all of this type of story, when it appears. Yet, they still insist on adding millions of years to everything. The way they describe the evidence as being preserved can also be explained by large areas of debris settling to the bottom of water flooded areas.

That's my opinion anyway.
