Exposing The Lies One Layer At A Time

More Arizona Geology Disproves Young Earth Creastionism

 

The Tonto Natural Bridge – A Creationist Nightmare 1.7 Billion Years In The Making

A slow cooling lava flow that became coarse textured rhyolite set the stage for what would become one of the most beautiful yet relatively little known attractions in Arizona 1.7 billion years later. This rhyolite became covered by horizontal reddish purple layers of sandstone that also included material from older formations in the area. Over time, the entire formation became lithified, faulted, tilted and much was eroded away, but the hardened sandstone remained leaving a prominent ridge. Then around 500 million years ago a shallow sea covered the area and limestone deposits began to build. By 300 million years ago even the erosion resistant ridge had been completely covered. The sea retreated, much of the limestone eroded, and new volcanic activity 80 million years ago covered the area with basalt. More tectonic activity created faults in the basalt and Pine Creek took advantage of this by following fault lines downstream and cutting through the basalt to expose and the layer of limestone below. Precipitation also took advantage of the faulting and seeped deep into the limestone exiting as springs into the valley. This dissolved limestone in the form of calcium carbonate is deposited as travertine. Much of it was eroded away by Pine Creek leaving the natural rock bridge or “tube” 400 feet long, 150 feet wide, and 180 feet tall that we see today.

Why is this a problem for young earth creationists? The fact that the volcanic Rhyolite and Basalt did not form underwater would be the first problem. Lava forming underwater leaves telltale signs such as pillowing and we see none of that in the immediate area. Fossils in the area limestone contain only very primitive life forms as we would expect, not a mixture of marine and land animals as a global flood might produce. Entire layers of sandstone and limestone present in the nearby Grand Canyon like the Kaibab Limestone, Toroweap Formation, Coconino Sandstone, Navajo Sandstone, etc. are completely missing from the area where Tonto Natural Bridge State Park is located and it takes a long, long time for such erosion to take place. Not even AiG, ICR, or CMI have attempted to try and explain this formation using “flood geology” from what I’ve seen.
