First, let me say I have absolutely enjoyed reading this book. I believe there is much truth on the pages.
On page 216 the question is asked “Are there Alluvial Fans being formed anywhere today?” The text leads one to believe there are not. But there are: the Horseshoe Park Alluvial Fan in Rocky Mountain National Park. When the Lawn Lake dam broke in 1982 it unleashed a torrent of water that created an Alluvial Fan. The Lawn Lake event provides support for the book. http://www.rmnp.com/RMNP-Areas-HorseshoePark-AlluvialFan.html
Modern Science’s chief mechanism for significant crustal events is uniformitarianism which says that all creative forces that are happening today have been happening only gradually throughout the history of the earth, as opposed to catastrophism which says that significant crustal events happen over a short period of time in one or more separate catastrophic events. The reason the Universal Model asks the Fundamental Question, “Are there Alluvial Fans being formed anywhere today?” with the follow-on answer of “no” is that alluvial fans are caused only by catastrophic events, not uniformitarian events which require all forces to be in constant effect over very long periods of time. Therefore, the question, “Are there Alluvial Fans Being Formed anywhere today?” refers to the theoretical Alluvial Fans that modern science claims are being formed through uniformitarian forces (wind, rain, etc.). Your example, Roger of a catastrophic Alluvial Fan is an example of many such catastrophic fan events that can be found throughout the earth, many of them more recent in modern times that have been documented through observation as was your example.
