a river's slow-motion victory over rock, carved one stubborn drop at a time
means A deep, narrow valley with steep rocky sides, usually carved by a river over a very long time.
from From the Spanish 'cañón,' meaning a tube or pipe (and, by extension, a deep gorge) — the same word that gives us 'cannon.' Both trace back to Latin 'canna,' a reed or cane, the image being a hollow tube. The term entered English from the American Southwest, where Spanish-speaking explorers met the dramatic gorges of the region and named them for their pipe-like channels.
