These one-page summaries for specific places present the history as nine chapters, an approach of Lehi F. Hintze. Dr. Hintze served on ESE Board of Trustees for over a decade, taking and leading sessions for teachers. Imagine how a cultural history of China in the 1600s would differ from a history of Europe, or Utah. Utah’s geologic history differs substantially from, for example, Connecticut’s. Tectonics Rules! The nine “chapters” of Utah’s geologic past simplify the effects of nine phases of effects of tectonics on what-is-now Utah. For example, Chapter Nine – Now Stretch, is the history of effects of extensional tectonics on Utah. Chapter Three – Shallow Seas is the history of relatively quiescent (not very active) tectonics when Utah was near sea level and south of the equator about a half-billion years ago. Teaching using numbers of years is staggering. Teaching the history using geologic terms can lead to jargon. Telling the history as nine chapters, specific to Utah, can be less intimidating than using geologic terms or quantifying in millions of years. That is Dr. Hintze’s approach and we adopt it in concept. He would be happily surprised by our charts, particularly the left columns which would delight him.
