Wibble, ironically you accused me of slothful induction. A cursory examination of AIG's articles in fact show that a flood can explain many of the features of Grand Canyon and the lack of expected long-age evidences, by majority. The majority of the evidence can't be explained by long ages.
The majority of the evidence seems explainable by a catastrophe carving it out, and there are many questions for long ages, many problems, but it seems you choose to focus on the relatively minor issues for a flood.
So if you focus on say two problems for a flood but ignore say ten major problems for long ages, is that fair?
AIG: Debris Not in the Present River Delta
Almost 1,000 cubic miles (4,000 cubic km) of material has been eroded to form the Grand Canyon. Where did it go? If the canyon was eroded by the Colorado River, an enormous delta should be found at the mouth of the river where it empties into the Gulf of California. But the delta contains only a small fraction of this eroded material.15 This same problem is found with most river deltas; they only contain enough material to represent thousands, not millions, of years of erosion.Stable Cliffs
One of the most striking features of the Grand Canyon is the massive sheer cliffs of sedimentary rocks. It is the difference in the rocks’ makeup that gives the canyon its color and progressive stair-stepped profile of cliffs above broad slopes. The cliffs are made mostly of limestone and sandstone, with some formations reaching 500 feet (150 m) in thickness. The dark, almost black, color of large sections of the sheer cliffs is due to a coating of desert varnish, which develops slowly over many years16 and is indicative of their stability. Where recent rockfalls occur, the desert varnish is missing. The fact that the cliffs maintain their desert varnish color indicates they are rarely experiencing even minor rockfalls; thus they are very stable. This is only consistent with their formation by recent catastrophic erosion, not millions of years of slow erosion.No Talus
The lack of debris, or talus, at the base of the cliffs is also a challenge to the evolutionary model. Over millions of years of erosion, one would expect to find large amounts of talus at the base of the cliffs within the Grand Canyon.17 The most obvious areas of this lack of talus is within the side canyons ending in broad U-shaped amphitheaters. Some of these amphitheaters are hundreds of feet deep and extend back as much as a mile (1.6 km) from the river. The majority have no water source to remove material, yet the bases of most of these cliffs are relatively “clean,” with very little talus. Within the evolutionary model, there is no mechanism for the removal of this material.Relict Landforms
The stability of the Grand Canyon cliffs and the lack of talus at their bases are indicative of the canyon being a relict landform. In other words, the Grand Canyon has changed very little since it was carved. It is a relatively unchanged remnant or relict of the event that eroded it, which therefore could not have been today’s slow river processes extrapolated back into the past.
