INTRODUCTION AND OUTLINE The Grand Canyon in Arizona is a natural wonder, up to a mile deep and eighteen miles across.A schematic of the rock layers is shown above [from 1992 article by Andrew Snelling with answersingenesis.org].The lowermost layer shown is the Vishnu Complex, consisting of rocks that have been deeply buried, heated, and transformed (metamorphosed).On one level, this is dishonest and deceitful, yet these folks operate with apparently clear consciences.The cognitive dissonance factor appears to be a reasonable psychological explanation for their behavior.Preface for blog: The first two-thirds of this essay deals with the rock formations of the Grand Canyon – what they are, and how and when they formed.
