Sixteen miles from Grand Canyon's south rim, a cone-shaped butte rises like a lone sentinel 1,000 feet above the Coconino Plateau floor. Thousands of tourists rush past on Arizona Highway 64 without giving it another thought, yet this humble little hill testifies to a remarkable past.

In August 2005, ICR installed a highspeed research computer and gave it the name Epiphany (to reveal or show forth) to reflect its purpose in using computer modeling to explore the natural processes of our world. Since then Dr. John Baumgardner, head of the ICR computer center, has conducted research on a range of topics.

Rocks exposed in the walls of Grand Canyon testify of the advance of marine waters upon North America during the Flood. How rapid was the advance? What was it like? We may never fully know the answers but there are few places on earth that are better suited for study.
