I went in that same creek years ago following another jeep & he ended up on his roof off that cliff. Pretty scary with no roll cage! Came down in the creek right behind me... wow, just figured out that was 6 years ago!

Driver of that jeep was ok, had a goose egg, but otherwise pretty good shape for the roof being at dash-level.
