This photograph was captured in the middle 1980s using Kodachrome ISO 25 film. It is the best of multiple attempts to photograph this scene.

Very basically sandstone fins form when the stone is uplifted from below, creating many cracks parallel to the axis of the lifting force. This often happens above large salt deposits. Over millions of years water and wind widen and erode the cracks, leaving stone fins. When weaker areas of such fins falls away, free standing stone arches are formed.
