Talk:Mouth of Colorado River doesn't have enough sediment for Grand Canyon (Talk.Origins)

The final comment may need more work.

" * Much of the strata exposed in the Grand Canyon are limestone and dolomite. These rocks eventually simply would have dissolved.

"This fact helps to show that the Grand Canyon could have been carved quickly. It could have been sped up greatly by sulfuric acid, since limestone and dolomite dissolve readily in sulfuric acid.

I think the talk origins argument is that the sediments would have dissolved and would not be present in the sediments, having dissolved and washed away. I am a layman, and cannot answer, but would be interested in what someone knowledgeable would say. This seems like it could be a good argument for the uniformitarian side, and we should answer with more information.--John Baab 13:34, 15 January 2010 (UTC)
