Capertee Valley is the largest canyon in Australia. It has a length of 19 miles and 1 mile depth.
We see the same pattern of parallel layers deposited. And after all the layers were formed, there is massive erosion.
Fish River Canyon is the largest canyon in Africa. “It features a gigantic ravine, in total about 160 kilometres (100 mi) long, up to 27 km wide and in places almost 550 meters deep.”
Again, same pattern.
The Taihang Grand Canyon in China also testifies to the pattern.
Charyn Canyon in Kazakhstan:
So, this pattern is not a local phenomenon, but a global phenomenon. All across the world, we see flat layers formed with practically no evidence of erosion or any geologic activity recorded in the strata, then after all the layers were formed, massive erosion took place.
