Grand Canyon: A Rim-to-River Time Machine

By Richard Kerry Holtzin

Short Synopsis: While writing this comprehensive text, I thought H.G. Wells would be impressed given the analogy of a 'grand' time machine where each step from the rim to the Colorado River equates to some 2,000 years back in time. In fact, within 10 miles (from the South Rim), the canyon's geologic formations represent differing geologic windows of time, starting around 251,000 years ago to nearly 2 billion years ago. This factual and well-researched Grand Canyon publication explains the how-what-why-where-when aspects whose educational field guide suffices as a personal tour guide (me) Abstract: From the rim to the Colorado River, the Grand Canyon is analogous to a time machine that begins about 250 million years ago and ends close to the two-billion-year benchmark. Thus, hiking down the South Rim's popular Bright Angel Trail to the bottom of the canyon (ten miles), each step averages 2,000 years All the relevant subject matter is explained in this factual, educational text--geology, and the particulars of how and when the Grand Canyon became a Natural Wonder, flora and fauna, prehistoric to contemporary human history, popular hiking trails, Colorado River ecology, things to do and see in the village, an abstract of the Colorado Plateau Province, of which the Grand Canyon is dubbed its crowning jewel, and other subject matter. Utilizing the Grand Canyon Village's timeline trail along a marked walkway to the east of the village, the text presents common details in an uncommon way. Specifically, a demotic style of writing that changes the academics of geoscience and natural and human history into casual parlance. The narrative, therefore, feigns a guided tour, only in a literary style while explaining the canyon's many facets of information without sermonizing. Moreover, the topics discussed along the way are presented at select vistas that break up the subject matter. This way, the reader is not overwhelmed with too much information at any vista. Given this layout and piecemeal presentation of facts and details, the text is a reader-friendly composition that engages and enlightens readers. The account of what there is to see and know beyond the scenery has also been exhaustively researched for accuracy, using a National Park Service heuristic teaching standard, as based on an interpretive explanation. Thus, the how-what-where-when and why factors.As a retired educator and instructor for the likes of the Grand Canyon Field Institute, most of what I did for a living for some forty years entailed teaching various geosciences, natural and human history; also environmental sciences, published writer, and mathematics.
