Ain’t skeptics nuisances?
Who among us has not seen a Louisiana map showing the Mississippi River’s delta, where the River dropped the soil it took from the states it traversed?
Well, if the Colorado River dredged the Grand Canyon, where did the River drop the debris?
I hiked twice from the Canyon’s South Rim to the river and back, once on the Bright Angel Trail and once on the South Kaibab Trail. I also floated down the river though the Canyon. It is one HUMONGOUS hole in Northern Arizona.
Where did the River drop what it took?
Why am I asking?
Partly, maybe mostly, because I’m a nuisance.
Also partly because there’s evidence that lightning - of the electrical kind - carved the Grand Canyon and much more of America’s west.
And, who are more skeptical than atheists?
Lightening carved the grand canyon instead of water erosion - ROFL. Extraordinary claims require extraordinary evidence, Tom. Meanwhile, the Colorado river doesn't even make it to the sea these days, due to people using its water. Meanwhile a simple search yields:
"Why don't all large rivers form deltas where they enter the ocean? Because the local coastal currents are so vigorous that no delta is formed, the stream sediment is simply swept away to be deposited elsewhere along the coast or offshore."
Ruth, where is your skepticism?
It’s you who accepted the extraordinary claim that children in geography classrooms have been hearing for many decades. Today’s geologists who know Northern Arizona say the river would have had to run uphill to cut the canyon into the Kaibab Plateau.
1) True, the River does not now go to the sea. Arizona’s farmers decades ago started ignoring the treaty that promised Mexico 25% of the River’s water. And this, where did the river go eons ago when it was ALLEGEDLY cutting the Canyon?
2) Where was the coastal current (in the long narrow gulf many miles east of the Pacific Ocean) that allegedly swept the sediment away?
Apparently there was a Colorado River delta.
Prior to the construction of major dams along its route, the Colorado River fed one of the largest desert estuaries in the world. Spread across the northernmost end of the Gulf of California, the Colorado River delta's vast riparian, freshwater, brackish, and tidal wetlands once covered 7,810 km² (1,930,000 acres)…
The Cucapá are descendants of the Yuman-speaking Native Indigenous peoples of the Americas and have inhabited the delta for nearly a thousand years. Spanish explorer Hernando de Alarcón made the first recorded contact with the Cucapá in 1540 and reported seeing many thousands. The Cucapá used the delta floodplain extensively, for harvesting Palmer's saltgrass (Distichlis palmeri), a wild grain which grows in salty soil; and for cultivating maize (corn), beans, and squash.
On the map the Delta was bisected by the river, but in fact the river was nowhere and everywhere, for he could not decide which of a hundred green lagoons offered the most pleasant and least speedy path to the Gulf.
Ruth, I appreciate your efforts but the Grand-Canyon-carved-by-lightning-eons-ago hypothesis:
1) has not been proved by my posts, and
2) has not been disproved by your posts.
Therefore, we do as scientists do; we suspend judgment, don’t we?
