As of 2006, The Giant Color Photograph of Beartooth Highway Was Still There!
….But Sadly Seems To Be Gone From March 29 2021 Internet Found Photos.

…. [ “ …we enter a restaurant] where we see on the walls huge photographs of the route we will take up. ]

This WAS just Inside and At Left of Front Door of Red Lodge Café. Due to too much illumination from the window, my first photographs of this Beartooth Highway Framed Photo were completely washed out.
….Later, I showed the restaurant owner the above ZMM passage. He was very interested in ZMM, and even purchased one of my ZMM copies. Understanding my photograph problem, he offered to change the window blinds for a better photo seen above.
In the /\ Above /\ Photograph (of the Giant Photograph of the Beartooth Highway Framed Photo),
..A) You will see peculiar "light strips": These are caused by the “back-lighting” of four vertical fluorescent lamps.
..B) You will have to "click on this photo to get the largest view”
……Then very closely study this photograph until you make out =>
….1) For the lower left portion, see two levels of twisty road cuts: Looking close, you see the Road Is Paved …. But there are NO Guard Rails !!
….2) At lower right edge, you can also make out, a small part of a loop switchback.
….3) Sloping down, across the upper center you see a major twisty white line. This is the tumbling “white water” of Rock Creek.
….4) One third of the way down the Photo’s Left Edge => You see sloping down a white strip which is a view through a Series Or Tree Branches & Trunks: The white comes from a Strip of Snow, just behind the Trees.
…. The above 1) thru 4) are examples you will see, more clearly, in the NEXT PHOTO, along with details => Who, Where & When of the /\ Above /\ Photo. .

NEW TOPIC => A Small Error In ZMM Book Narrative.
….The above ZMM passage says “ on the walls huge photographs of the route we will take up … .
…However, as you have seen for => The Red Lodge Café's Walls,
..a) There are Huge Paintings of Mountain Scenery: But none these showed “ the route we will take up … . “, and
..2) There is really only one Huge Photograph which does show “ the route we will take up … . “: This is shown in /\ Above /\ Photo.

Concerning Overall Accuracy Of ZMM Book Travel Narrative.
….After completing my 2002 ZMM Route Research Trip I realized overall that => Robert Pirsig’s ZMM Travel Narrative is Very Factually Accurate, with very few departures from the actual scenery, I was able to find.
….The ~ 6 major exceptions to this, Mr. Pirsig himself has given the reason => At the beginning of ZMM, he says =>
…. Author’s Note
What follows is based on actual occurrences. Although much has been changed for rhetorical purposes, it must be regarded in its essence as fact.
****
I believe that Mr. Pirsig’s way to achieve his as fact. , was to be both interesting and very, very, absolutely factual with his travel scenery.
….My research concerning Mr. Pirsig's Travel Narrative demonstrates that he did achieve his own above stated “as fact” criterion: He held his book to "Good old reality."
….To quote Professor Robert Nelson, "[ ZMM Book's ] plot remain consistently responsible to the topography of the physical landscape through which the protagonist moves ."
