Sooo, dental, bbq or truck parts………

 

Just wondering the same thing. We need some clarification here.

 

For it to be a Valley, it has to be primarily created by glacial or river erosion - so I’d say it’s a basin.

 

It was created by river erosion. The Salt River. Hence the name, "The Salt River Valley".

 

You know more than the salt river flow to the Phoenix river basin, right? Like the Gila, Verde, Agua Fria…

They are just geologists and stuff.

 

"In the geologic literature, valley refers to a modern physiographic feature, whereas basin refers to a subsurface feature"

It is basically saying that the Phoenix area is a basin and also a valley. The valley is the geologic surface structures while the basin is the subsurface structures, namely, the underground water reservoirs and such.

 

The salt river is just a tributary of the Gila river. It starts at the joining of the Black and White Rivers then travels for roughly 200 miles, then reconnects with the Gila river. It isn't a basin. It is a valley. A very wide valley.

If you want to call it the Gila river basin, then you have to go well outside of phoenix and include the entire southern half of Arizona. Phoenix is located in a single valley, the Salt River Valley, within the Gila River basin.

 

And the Gila is a tributary of the Colorado - has nothing to do with the geographic landform of the basin upon which Phoenix sits. Show me one textbook illustration of a valley that shows a 50+mile bowl shaped landform… U’s or V’s make a valley - not 50 mile circular flat spot. Tucson isn’t a valley for the same reason. Sorry you’ve been lied to your whole life but “Basin of the Sun” didn’t have the same ring. Too bad the “Old Pueblo” was taken.


The Salt River Valley is beautiful - full of wild horses and kids tubing east of Mesa.

 

I heard it was full of something else after last weekend too

 

Lol. She’s two and there was no way we were making it back to the marina. I’m sure it sank eventually.

 

You are missing my point.

I'm not saying that because the Salt river is a tributary that it has to be a valley. I am saying that the Salt River created its own valley within the Gila river basin. And the "Valley of the Sun" is so named because Phoenix resides within the Salt River Valley, which is within the Gila River Basin.

And a valley is not defined by its shape. A valley is "An area of low land between hills or mountains, typically with a river flowing through it."

And the Salt River Valley is not a 50 mile wide bowl shape or circular flat spot. The City of Phoenix is NOT the same exact size as the actual Salt River Valley. The actual Salt River Valley is about 200 miles long and yes, is very wide. And the city of Phoenix was built at one end of it, not even in the middle.

And as in the nature of very old, slow moving rivers, the river changes course many times over hundreds of thousands if mot millions of years, and can carve out very wide valleys. The river can also deposit sediment, refilling various previous river paths during flash floods and such. Here is a geologic survey from 1905 describing exactly that, among many other natural phenomena around the formation and more recent structure of the Salt River Valley: https://pubs.usgs.gov/wsp/0136/report.pdf

It should also be worth noting that over the decades/centuries/millennia, we have moved a LOT of soil around. Leveling things out, filling in depressions, and cutting down high points. The land Phoenix was built on was not this level before the city was built.

Saying that Phoenix is a basin is like saying that Arizona is a continent, just because it exists within the borders of North America.

 

Better tell National Geographic to fix their reference page.

https://api.nationalgeographic.com/distribution/public/amp/science/article/valleys
“Valleys are depressed areas of land–scoured and washed out by the conspiring forces of gravity, water, and ice. Some hang; others are hollow. They all take the form of a ‘U’ or ‘V.’”

 

Ok. I will be sure to write an email to the ENTERTAINMENT MAGAZINE about how they got it wrong by being too vague and "dumbed down" for public mass consumption.

Meanwhile, you should check this out: https://www.britannica.com/science/valley In particular, this part that says: "Further downstream, valley floors are wider and often dominated by floodplains and terraces."

As it turns out, there are many types of valleys, all formed by different processes, or similar process with different conditions. Some valleys are steep walled V channels, but others are very broad flood plains or wide, flat bottomed, river beds. And some are just the space where two mountains meet each other and have absolutely nothing to do with water flow.

National Geographic is actually the product of the National Geographic Society, a world wide non-profit organization educating people around the world (some) about geography and culture for the past 150 years. Not exactly National Enquirer.

 

Some of us want to be valley girls……

 

As a non native who came here "for 6 months" in 2006, I say not me, it's too hot to give 1/2 a fuck!

lol

 

But





















Is it?

 

Amen to that subject! LOL.

 

Came to this thread and…..

 

Ok? Still not a legitimate scientific publication. And as I implied in my earlier comment, they sometimes simplify things to the point of being wrong, precisely BECAUSE they are trying to appeal to a broad audience.

It's that whole thing where as you get older and go into higher education, you find out the things you learned in elementary school aren't actually true. Ask almost anybody if there is gravity in space. Most people will say "No, of course there is no gravity in space." but that isn't true. Even the astronauts on the space station, floating around inside, are still under the effects of about 95% of earth's gravitational pull. There is about a quarter of a million miles between the Earth and the moon, yet they are both under the influence of each other's gravity so strongly that the Moon is tidally locked and can't spin, which is why we always see the same face all the time. Space is chock full of gravity everywhere. But when you want to explain space to children, or to people with little to no interest in science, you oversimplify and say "there is no gravity in space." And THAT is what National Geographic does.

 

Who gives a fuck about anything? Why are you even on this forum? Who gives a fuck about Tundras? Who gives a fuck about Baseball? Who gives a fuck about inflation? Who gives a fuck about literally anything that anybody else has any interest in?

That's the thing about conversation. You don't have to be interested. But just because you aren't interested doesn't mean that nobody else is. Hate to break it to you, but not everybody thinks like you or is interested in the same things as you. Whatever it is you are passionately interested in, is boring schlock to other people.

 

Do you believe in the chupacabra?
