Oh, I see, you just want the free shipping...
Kings Canyon, California.
i think it's hell's canyon, but you'd have to look that up to be sure.
good luck

Hell's Canyon claims to be the deepest in North America. So does
King's Canyon. So does Copper Canyon (though its real name calls
it a barranca rather than a can~on).
So who decides? How does one measure?

eh?
I think this just changed.
Anyone with, I believe the 1994 American Alpine Journal (I think that
year and not 1993 or 1995), could check for a two page article by
Brad Washburn. My climbing partner Keith Echelmeyer is noted by
Washburn as doing a new sounding (high explosives again) of the Ruth Gorge
and establishing that as a new "record." Of course a glacier sits in
the rest of the trench. So you either have a chance to "get it right."
Or correct Sierra Trading Post. Just find the article. Otherwise
insist on deepest non-filled canyons.
As a side note, does anyone know about the geology of Copper Canyon?
My mother visited Copper Canyon last month, and her description
sounded like extensional faulting. But she's not a geologist,
or even anything similar. I know a planetary scientist who's
interested in terrestrial analogs to Martian geologic features.
He'd be interested if Copper Canyon was produced by extensional
faulting, because that's a _much_ better analog to the Marinaris
canyon system on Mars.

Nope. It'e the gap betwixt hunters and anit-gun proponents. Nope... it's the
chasm between religion and science. Nope! It's the divide between Demo and Rep.
Nope! It's definitely King's Canyon!
How about deepest VALLEY in N. America? Anyone care to take a stab at that?

Careful with the political jokes. What goes around comes around.
I don't think Barranca del Cobre is deeper than the Grand Canyon, but it has
a greater volume, least, that's what I always heard.

It's kind of like a "first ascent."
Measurement is fairly easy, it's the decides which makes the problem.
The measure will take known surveys: topographically and combine that
other known facts like seismic work in the case of the Ruth's Grand Gorge.
The "decides" is typically some declaration by locals colliding with
specialists. R.b. got started shortly after a "what's the steepest road"
discussion (one noting a steep road in the Waipo Valley on the Big Island
of Hawaii).
Like net discussions, people pose things, and they get knocked down by
verifiable (and repeatable) tests and qualifications (like "North
America)".
Serious claims go to places like the Geographic Board of Names (the
panel 16 of the real world), the USGS, and numerous "authorities."

That makes the basin at least 9534 feet deep

While Hells Canyon does not have the relief of the Grand Canyon, it is
the deepest.
