Catastrophe for Uniformitarian Geology

Evolution's True Believers™ circle the wagons when someone shows flaws in their "the present is the key to the past" paradigm, and insist that long-term gradual processes are true. This happens despite observed evidence, not because of it. Geologists themselves will reluctantly put their beliefs aside for a spell when they can't get around the evidence.

Occasionally, uniformitarian geologists are forced to admit that catastrophic processes existed in Earth's past, but they do this reluctantly. Research at Deitfoss gave them some uncomfortable information.

Geologists of the biblical creation persuasion believe that the Genesis Flood shaped much of the world's surface features (one model is called "Catastrophic Plate Tectonics"). But evolution requires long ages, and having a lot of water in a little time is the opposite of their flood geology of a little water in a lot of time. When secular geologists see evidence for catastrophe from their own sources, they unenthusiastically make some allowances for such processes, even though they don't understand them.
Europe’s biggest waterfall likely formed catastrophically instead of gradually, a new analysis reveals.

The Detifoss waterfall in Iceland is the terminus of a 28-km canyon that is 100 meters deep in places (see canyon photo on Science Daily and waterfall photo on Science Magazine). The canyon was formed rapidly in “dramatic floods,” Science Magazine says, that may have been thousands of years apart.

The new study was published in PNAS by researchers who studied helium isotopes at various locations in the canyon. The isotope ratios were so similar, they concluded that the dates of the falls, canyon and rim were nearly contemporaneous.
