IT LOOKS LIKE 'X’ SO IT MUST BE 'X’
TB condemns my pointing out that a similarity in appearance of certain objects might indicate they have a common cause, e.g., the Grand Canyon and Lichtenberg patterns formed in grass by lightning strokes. He then goes on to say that Mark Twain “noted how the [Mississippi] river course would change, with no reports of giant electric arcs.”
There are many morphological characteristics of the Grand Canyon that are enigmatic for 'standard' geologists. Different from the Mississippi (and similar to Lichtenberg patterns), it has no delta, it is narrow at both ends, and its tributaries are as deep at their beginning points as they are when they join the main stream; many such tributaries join at right angles to the central valley. And, of course, it is a mile deep. Also, there is the old saying: "If it walks like a duck, and quacks like a duck……."
