I think most evolutionists who know anything about geology recognize two things: catastrophes can and do produce rapid and even sudden changes, and that the tearing away of layers in strata can happen very rapidly.
We can look at Mt. St. Helens and see rapid catastrophic change in the geology of the area. We can look at the nearby Columbia Gorge and see what a dam breach can do in terms of sudden changes.

for the old age formation explanation of the Gorge, which nevertheless shows very rapid processes.
Do we have any evidence geologically of rapid processes building up strata? Yes. In South Australia, near an area called Second Valley, if you travel out to the coast and walk around a bend, you will see some remarkable folding which shows NO signs of cracking during the folding process. This means that all the layers were new and warm together during a layering process that also involved earth movement. We took pictures of this remarkable formation and they are at our website here:

We think it is excellent evidence for rapid formation, thus at least in part denying the long ages ideas presented by Lyell and needed by evolution.
