not obviously dude. there's that sandy-colored rock sediment in MANY places around the world! i'm not even sure it is the Grand Canyon to be honest, in fact, and i am american and have been to the G.C., i'm 99% sure it's not. this could be anywhere in the Sierra Madre-Rockies formation from Mexico to Canada. it DOESN'T MATTER! smoke a doob bro and just enjoy the pic.
I prefer these shots where the water looks more natural, rather than a blurry stream. I wonder what the river looked like when it was cutting that rock away.
