Not the full story. FAR 91.119 applies (note 1).
Per 91.119(c), over non-congested areas, aircraft can be as low as 500 feet AGL. And per that same section, over sparsely populated areas (looks pretty rural in satellite images), aircraft need to be 500 feet (slant range) from any person, vessel, vehicle, or structure.
Per 91.119(d), helicopters may be operated at less than these altitudes.
