"The Three Days of Darkness," has more obvious immediate relevance to the concerns of this Review. (The editor makes it clear later in the book that he believes the Grand Canyon to have been a sudden occurrence, connected with the earthquakes which, according to the Book of Mormon, accompanied the crucifixion of Christ.) The myth purports to have taken place at Rush Lake, west of Parowan, Utah, and tells of the three days of thick darkness which fell over that area when Un-Nu-Pit, the devil, killed the younger god, Shinob. It was impossible even to kindle fire, and the people were near despair. Fortunately, the voice of Tobats pierced the darkness, and that god finally found a way to disperse the gloom. Later, in revenge, he slew Un-Nu-Pit and thereby brought Shinob back to life.
The editor expressly takes this event, as well as the previous story of the creation of the Grand Canyon, as literally historical. (He points, in this context, to the numerous cinder cones which dot southern Utah.)

Paracas, Peru - a megalithic carved stone split in half. I asked what could have caused so much volcanic and
earthquake activity. The meteor crater was shown as an answer to that question. What could have split this boulder?
I would say that it was split by earthquakes with volcanic lightning at the Crucifixion.
Two Pahute Indian Legends: "Why the Grand Canyon Was Made" and the second myth, "The Three Days of Darkness," has more obvious ... west of Parowan, Utah, and tells of the three days of thick darkness which fell over that area ... taken place in Mesoamerica - or even, if we follow Priddis, in South America.

The 100 ton megaliths of Puma Punku, Peru - broken by earthquake and submerged in a flood of mud. Was this caused by massive volcanic snowmelt with earthquakes? Volcanic eruptions create their own lightning storms.
