Claim CH550:

Response:

1. Varves within the geologic column show seasonal layers over many, many years. In many cases, such as the Green River formation, these layers are too fine to have settled out in less than several weeks per layer. Varves in New England show evidence of climate change 17,500 to 13,500 years ago, which matches climate patterns in other parts of the world (Rittenour et al. 2000). These layers prove that the geological record was not produced in just one event.
   
   
2. There are many different kinds of surface features preserved in the middle of the geological column. These features include soils, mud cracks, evaporite deposits, footprints, raindrop impressions, meteor craters, worm burrows, wind-blown sediments, stream channels, and many others. For example:
   
   
   • The Loess Plateau in China has a layer of loess more than 300 m thick. Loess is wind-blown sediment that would not occur during a global flood. The Loess Plateau occurs around the downwind edges of the Ordos Desert, its source of sediments, and the grain size of the loess decreases the further one gets from the desert (Vandenberghe et al. 1997).
     
     
   • The Loess Plateau includes paleosols within it. These are buried fossil soils, some of which would require tens of thousands of years to form (Kukla and An 1989; Liu et al. 1985).
