Regional geology as a unifying theme and a springboard to Deep Time
M. G. Miller 2001 Journal of Geoscience Education v49 no1 p10-17
Miller (2001) teaches Earth History within regional contexts in his course 'The Geology of National Parks'. He emphasizes the geological relations of the strata, principles like superposition, and rates of deposition and uplift. The National Parks offer a wide variety of geologic processes and strata of different ages. Miller has his students work out how long it would take to deposit various formations, given modern deposition rates, then asks why rocks of a given age are thicker in one area than at another. The discussion of unconformities and variable deposition rates reminds the students that even the Grand Canyon, which exposes tens of millions of years of sedimentation, only represents a fraction of Earth's total history. Radiometric ages are discussed only at the end.
