Collin this looks like a dust storm to me. You know down in Oklahoma they have orange dirt that must have looked a lot like this during the Dust Bowl days (early 1930s). I saw a bad dust storm in North Dakota too but the dirt is black there so it really did look like a dark fog, and you got home with dirt in the mouth and eyes. Oh, and if this is dust, thank goodness you shoot with Olympus!
