Some of you have a bad habit of mixing up threads. If I didn't respond there yet it is either because I haven't had the time or it wasn't worth responding to. I gave you an excellent explanation of how geologists date layers in the geological column by using both absolute and relative dating methods. A bunch of quotes by people I've mostly not heard of is nothing but a very weak attempt at an argument from authority and the people you quoted would have probably agreed with my explanation anyway.
I'm going to show you the absurdity of your claim that someone needed to be there for millions of years to watch the varves form or it isn't real science.
You wrote : "Steve Austin, who has done much field work at Mount St. Helens, documented in his new book Grand Canyon: Monument to Catastrophe that the volcano eruption produced 25 feet of volcanic ash varve-like deposits from hurricane-velocity surging flows in five hours."
Was Steve Austin there? Did he watch the 25 feet of ash layers form? Did he see each layer form?
That is basically what you are trying to do when you say "Where was your observer who lived over countless thousands or millions of years to verify your claim? Name him."
Annoying, isn't it? Shows a basic lack of understanding how science works, too.
