Using Ron Blakey’s amazing geological maps over time, Wayne Ranney explains life on the Colorado Plateau over the last 500 million years and how those environments lead to today’s formations. He also explains (23:20) how the data gathered by thousands of field surveys are distilled into this new breed of useful geologic maps of the surface of our planet.
Which brings us to the Geologic Column, in essence it’s a vertical geologic map, a cross-section of Earth’s crust. Wayne’s talk is filled with insightful information that brings alive our planet’s deep history while underscoring the makeup and validity of Geologic Column.
