Whose mountain is this?

Magnet #1251 - Mountain Valley

So here's the thing - I bought this random set of magnets from...well, Staples (shut up! I buy 'em wherever I find 'em). And the other three are like the Grand Canyon, a random cactus and what I think is like the Grand Tetons or something.

The point being, that this magnet should theoretically be a mountain valley in the United States.

Only, honestly, it feels like it's the African desert, kinda like how it looked in Hatari! (shut up! My favorite John Wayne movie!)

So I leave it up to you, Dear Reader to figure it out...
