Montana Passes

Montana has a lot of mountain ranges and it has a lot of miles of continental divide.  These physical features provide a
great many scenic locations and there are consequently a large number of passes to allow travel by train or automobile
across and through these often formidable barriers.  In addition some challenging highway climbs are known as a "hill"
rather than being designated a pass. 

We will arrange our photos by starting at the Montana, Wyoming, Idaho boundary and going northward up the Montana-
Idaho border.  We will then return to the continental divide near Sula and follow it northward to Glacier Park.  Finally, we
will visit the more isolated passes and hills that are not located on these well defined continuous elevations.
