The Enigma of Arches and Natural Bridges

Yes, we have discussed arches and natural bridges in"Stone Arches, Bridges, and the Genesis Flood" and "Crumbling Landforms", the article linked below provides a very good treatment of the subject (and not everyone has read every post here, of course). Flaws in a new hypothesis by secularists are also mentioned. The article also clarified for me the difference between an arch and a natural bridge.

Large natural bridges and arches are puzzling to secular geologists since they cannot adequately explain them.

If you get a notion to saddle up or hike so you can see natural bridges and arches, don't be going on them. Secularists claim they've been standing for millions of Darwin years, but the things have been collapsing of late. Uniformitarian geologists cannot explain the large ones, even though they are clearly the products of erosion. Small "windows" have been formed rather recently.

Nobody has seen such structures forming, and their existence is baffling to uniformitarian geologists. Some of their ideas don't take into account all the facts and some basic geological science. Even so, the best explanations are related to the Genesis Flood. Not during, but afterward, including the massive erosion in the runoff of the waters.
The origin of arches and large natural bridges is problematic for uniformitarian science. Many hypotheses have been suggested, but all depend upon slow processes of erosion over tens of thousands of years. The problem with this much time is that the large natural bridges and arches would have weathered and collapsed long before the material around them eroded. Geomorphologist C.H. Crickmay noted that for large natural bridges to form, its erosion rate compared to the stream channel has to be almost non-existent, which makes no sense when considering that a natural bridge in its beginning stage will erode fast by rock fall.
