Mississippi delta could have formed in 5000 years (Talk.Origins)

Claim CD211:


 * The size of the Mississippi River delta divided by the sediment accumulation rate gives an age of less than 30,000 years, indicating a young earth.

Source: Pathlights, n.d. The age of the earth - 2.

CreationWiki response: The wording of this claim is contrary to that of the cited source. The source actually calculates the age of the Mississippi River delta at 4,620 years not 30,000 years.

This is true, but calculating the actual age of the Mississippi delta requires estimates of past disposition rates, and such estimates will probably be different in Flood geology and Uniformitarian geology.

It is not the delta that is seven miles thick, but rather the sedimentary rock upon which it sits. Furthermore these layers extend several hundred miles into the Gulf of Mexico, as such the sediment is spread out as would be expected from a single flood.

 * 1) This a purely Uniformitarian interpretation and as such has no bearing on Flood geology.
 * 2) A map of these alleged past coast lines show no hint of a Mississippi River delta.
