"Fine laminae from only a millimeter thick to more than a meter high formed in just a few seconds each. A deposit more than 25 feet in thickness, and containing upwards of 100 thin layers accumulated in just one day on June 12, 1980. Naturalists have long claimed that stratified layer such as those found in the geological column have accumulated over vast periods of time, and these laminates represent long season variations or annual changes.

The stratification visible in the Grand Canyon is comprised of thousands of layers of different rock, some sedimentary, some igneous, some metamorphic. What this picture shows is two layers of unconsolidated ash.

The strata have many causes, most of which do not equate to regular seasonal deposition.

" However, the Mt. St. Helens deposits have demonstrated that catastrophic processes are able to create these geological formations in a short period of time.

There is a major difference between the time required for erosion of unconsolidated ash such as you show and the much different material cut through in the creation of the Grand Canyon.
