That's one deep canyon

From the Grand Canyon National Park website:
"At its deepest, it is 6000 vertical feet / 1829 km from rim to river."

Holy cats! That's more than 20% of the way to the core of the earth! (In metric, at least.)

Coolness, yet just think. There's a "Grand Canyon" on Mars that's almost four times as deep as our Grand Canyon.

Wowsers! That's more than 80% of the way to the Earth's core, and isn't Mars smaller than the Earth? That must mean... It goes right through! Mathematical/logical discovery by Dean: Mars has a hole in it.

Ha ha, I meant four times as big (length, width and depth). Ha ha. Anyhow, here's one reference. Wikipedia is not the best, but I couldn't find a better geology site reference, and I'm feeling lazy:
