Abstract
Shallow-water lime muds in today's tropical oceans accumulate at a rate of one foot thickness per one thousand years. These muds are formed by mechanical breakdown of carbonate containing sea creatures. Modern muds are believed by evolutionists to provide an excellent example of how ancient lime mudstones ("micritic limestones") were accumulated in Grand Canyon. Even some creationists believe that the evidence from lime muds is so convincing that one must certainly believe in long ages of slow deposition for Grand Canyon limestones. Dan Wonderly, for example, insists that all one has to do is compare the modern lime muds with the texture of the Redwall Limestone of Grand Canyon to be convinced that the Canyon strata required millions of years to be deposited. Wonderly claims that young-earth creationists, in a very deliberate way, ignore or neglect these data, which prove slow deposition.
