How are very deep and tight horseshoe bends created in canyons?
The most famous known example is called Horseshoe Bend in Arizona and it is a spectacular example of this type of dramatic U bend in the Colorado river.
Does the Horseshoe Bend geology with its precious stone garnet and metals show that there has been a large Electric Universe Geology event or multiple EU geology processes here? That perhaps helped form this and other horseshoe bends?
Or are all the impressive entrenched horseshoe bends purely down to river water erosion processes combined with uplift as geology suggests?
Horseshoe Bend, Colorado River
Before this plateau formed, the Colorado River flowed across the land like any other. The middle course – which is where you find meanders like Horseshoe Bend – is where the stream has the most energy and water. The fast-flowing water carries stones, sand and corrosive substances, which together create an erosive force to be reckoned with.
Like all meanders, the bends in the Colorado formed due to a cycle of erosion and deposition. First, the outside of the bend – where the water flows fastest – is worn away. This eroded rock and sediment is then deposited by the slower- flowing water inside of the bend. The continuous erosion and deposition causes the river to meander and migrate downstream.
Dramatic landforms like Horseshoe Bend emerged after the gradual uplift of the Colorado Plateau caused the river to carve its path down through the ancient sandstone, instead of eroding from side to side. This is because water will always follow the steepest route. Over millennia, the banks of the river grew ever steeper, until eventually the river became entrenched at the base of a canyon.

Or when the Horseshoe Bend entrenched meander was formed?
The rock walls of Horseshoe Bend contain a variety of minerals, among which are hematite, platinum and garnet.

Why has the Colorado river not silted up with just the Horseshoe Bend sediment, let alone all the other bends, turns and the Grand Canyon sediment itself?
Horseshoe Bend on the Colorado River is an entrenched meander, located just below the Glen Canyon Dam in Page Arizona. While most meanders are found “meandering” back and forth across the alluvium of a river’s flood plain, an entrenched meander is cut into the bedrock.
This type of meander forms when land under a meandering river is uplifted by tectonic forces thereby rejuvenated the river, giving it additional power to erode downward into its bed. If prolonged over hundreds of thousands of years, such erosion may form a gorge.
At Horseshoe Bend, the Colorado River has cut through eolian Jurassic sandstones creating scenic Glen Canyon.
