Friday, July 19, 2024: …From A Rt-2 Bridge, Looking Northeast, A View Of The Jefferson River 15 Minutes And 1.9 Miles, After Leaving The Town Of Three Forks, MT.
…From Here, The ZMM Route Continues Traveling Rt-2 Northwest For A Half Mile, Then Turns Southwest Onto US-287. After Trending Southwest About 11Miles Rt-2 Leaves US-287, To Turn Generally West, Which For Many A Mile Follows The Above-Mentioned Jefferson River. GPS = 45.8971457, -111.5966647

The ZMM Narrator Says =>
….It had long been sought in vain, he said [Poincaré], to demonstrate the axiom known as Euclid’s fifth postulate and this search was the start of the crisis. Euclid’s postulate of parallels,
….Finally, in the first quarter of the nineteenth century, and almost at the same time, a Hungarian and a Russian—Bolyai and Lobachevski—established irrefutably that a proof of Euclid’s fifth postulate is impossible. …….
….It wasn’t the proof that was alarming. It was its rational byproduct that soon overshadowed it and almost everything else in the field of mathematics. Mathematics, the cornerstone of scientific certainty, was suddenly uncertain. .
….We now had two contradictory visions of unshakable scientific truth, true for all men of all ages, regardless of their individual preferences……..
….This was the basis of the profound crisis that shattered the scientific complacency of the Gilded Age. How do we know which one of these geometries is right? If there is no basis for distinguishing between them, then you have a total mathematics which admits logical contradictions. ……
….And of course once that door was opened one could hardly expect the number of contradictory systems of unshakable scientific truth to be limited to two. A German named Riemann appeared with another unshakable system of geometry which throws overboard not only Euclid’s postulate, but also the first axiom, which states that only one straight line can pass through two points. Again there is no internal contradiction, only an inconsistency with both Lobachevskian and Euclidian geometries.
.. .. According to the Theory of Relativity, Riemann geometry best describes the world we live in.
.... At Three Forks the road cuts into a narrow canyon of whitish-tan rock, past some Lewis and Clark caves. East of Butte we go up a long hard grade, cross the Continental Divide, then go down into a valley.”

We Have Just Passed The Town of Three Forks, MT, And AFTER The ZMM Narrator finishing With The Mathematics Of The Three Geometries, Where Only One Geometry Is Found Useful, And Which Is Productive.
…And, AS IS THE CASE OF The Three Mathematical Geometries, =>
…..The Narrator Here (In /\Above/\ Passage, Near The Town of Three Forks, ) Must Chooses Between =>

….[“According to the Theory of Relativity, Riemann geometry best describes the world we live in.
.... At Three Forks the road …. cuts into a narrow canyon of whitish-tan rock, past some Lewis and Clark caves. East of Butte we go up a long hard grade, cross the Continental Divide, then go down into a valley. “]

Seven miles Southwest of Three Forks, MT. Although this interesting place is unmentioned by the ZMM Narrator, it nevertheless is worth a stopover. In a very picturesque setting, the Parker Homestead is a park for public visit and a resting place.
….I again traveled the ZMM Route in September of 2006 and decided to take this photo and place here for your interest.
….It is striking how different the color change is due to later in the season. This photo is part of an 8 shot 360 degree panorama, which will be eventually placed up in my ZMMQ Panorama Album.

..A) As The Previous Photo (Re Three forks, MT), Discussed At Length => .where you will often notice in ZMM => The Name Of The Town is used to Metaphorically / Poetically to support the current Chautauqua Lecture. As we eventually learn => This is Mr. Pirsig's stock-in-trade in both ZMM and Lila.
….In addition, Author Robert Pirsig has added into the ZMM Travel Narrative, what in ZMM Gallery Photos is called, => ”Metaphoric Bridge-Connections." At first, I was slow to catch on to these! It took me about 4 readings of ZMM before I finally said,=> "Hey, what is Pirsig doing here?" I started to watch for these "Connections" and was amazed to note that => At every abrupt switch between Chautauqua, and the Travel Narrative Description, this Connection" was ALWAYS there! This eventually led me to newly define the idea of "Metaphoric-Bridge-Connections".
….Many of the more outstanding examples of Mr Pirsig’s ”Metaphoric Bridge-Connections.", are discussed in many ZMMQ Gallery Photos. In such photos, along with my photo explanations, I point out these “Poetic / Metaphoric Bridge Connections” such as the following examples, that involve the use of a Town's NAME, as you see next =>
..****************..

EXAMPLES OF THE ZMM NARRATOR’S METAPHORIC USE OF TOWN NAMES =>
..A) Marmarth, ND, Hot, Tortured, Dry, Damaged, Muddy, Marred Notice how the town’s atmosphere and evident town abandonment, fit the Narrator’s description of the surrounding harsh terrain and the “death-birth continuity” of ZMM passage. Even the town name Marmarth, like that of Herreid, poetically suggests an awful place.
..B) "Baker, ND, Everything Is So Baking Hot! “At Baker,, where we stop, the thermometers are reading 108 degrees in the shade. When I take my gloves off, the metal of the gas tank is so hot I can’t touch it. The engine is making ominous knick-knicking sounds from overheating. Very bad. The rear tire has worn badly too, and I feel with my hand that it’s almost as hot as the gas tank. “
..C) Herreid, SD, Everything Is Horrid.
A Dangerous High Speed Truck Route Passes Through A Town Name Herreid, SD. Which (As Seen ZMM Passage), ZMM Author Pirsig Poetically Applies As “So Very Horrible” Herreid!

..D) Lemmon, ND, Everything Is Sour.
….By the time we reach Lemmon, we are really aching tired. At a bar we hear about a campground to the south. John wants to camp in a park in the middle of Lemmon, a comment that sounds strange and angers Chris greatly.“
..E) Prineville Junction, OR, Everything Is Prinnie, Pruny, Prickly Bad .
…. We arrive in Prineville Junction with only a few hours of daylight left.
... am so tired I go around in back and sit on the yellow-painted cement curb with my feet in the gravel and the last rays of the sun flaring through the trees into my eyes. Chris comes and sits down too, and we don’t say anything, but this is the worst depression yet. All that talk about gumption traps and I fall right into one myself. ….Fatigue maybe. We’ve got to get some sleep.
….I watch the cars go by for a while on the highway. Something lonely about them. Not lonely—worse. Nothing. Like the attendant’s expression when he filled the tank. Nothing. A nothing curb, by some nothing gravel, at a nothing intersection, going nowhere.”

.F) Also Good Metaphoric Candidates Are The Towns of => White Bird, ID, and New Meadows, ID.
….****************..

….SIDE NOTE:
….The above are good examples of how Author Pirsig, uses Town Names Poetically & Metaphorically, to reflect upon BOTH the Travel Narrative & Chautauqua Topics at hand. … And in my ZMMQ Gallery Photos, such as you are looking at right now, this usage is many times pointed out and discussed with the photo.
….However, most of my ZMMQ Gallery Photos were posted long before the NAME => ”Metaphoric Bridge-Connections" had been invented. And o/c is the reason you can’t use the MBC Words to Google for these examples.
… Additionally, you the reader (having read this discussion) now will have to supply the MBC idea, whenever there is => An abrupt switch between Chautauqua, and the Travel Narrative Description,.
....If you notice other examples, please send an Email, telling what you have found. ************** .

HISTORY OF THE THREE FORKS OF THE MISSOURI.
...The Below, Published On Facebook.com, 28 July, 2022 by David Matos.

….On July 28, 1805, Meriwether Lewis put pen to paper and recorded a consequential decision…
….“Both Capt. C[lark]. and myself corrisponded in opinion with rispect to the impropriety of calling either of these streams the Missouri and accordingly agreed to name them after the President of the United States and the Secretairies of the Treasury and State having previously named one river in honour of the Secretaries of War (Dearborn's River) and Navy (Smith's River). In pursuance of this resolution we called the S. W. fork, that which we meant to ascend, Jefferson's River in honor of that illustrious personage Thomas Jefferson. the Middle fork we called Madison's River in honor of James Madison, and the S. E. Fork we called Gallitin's River in honor of Albert Gallatin.”
….Lewis & Clark and their Corps of Discovery had arrived at the headwaters of the Missouri River on July 25, 1805, Their Lemhi Shoshone guide Sacajawea recognized the area as the place she had been abducted from her people years earlier. A scouting party led by Clark went ahead to the Three Forks, where three meandering rivers merged into the Missouri Rivers. Instead of identifying the largest of these three rivers as a continuation of the Missouri River, Lewis & Clark decided to name it as a tributary, the Jefferson River. As a consequence, the Mississippi River is technically longer than the Missouri River today.
….Lewis, upon arriving at the Three Forks of the Missouri, decided…
…….“beleiving this to be an essential point in the geography of this western part of the Continent I determined to remain at all events untill I obtained the necessary data for fixing it’s latitude Longitude.”
….Sacajawea would eventually reunite with her Lemhi Shoshone in a tearful, affecting reunion, meeting her brother now a chief, and another female abductee who had previously escaped and returned west. Sacajawea and the Shoshone’s help were crucial in making the Corp of Discovery’s expedition a success.
….Today the Three Forks of the Missouri Region, is part of Missouri Headwaters State Park in Montana. The Gallatin River of course would give the name to Gallatin County that the Three Forks of the Missouri is located in. Sacajawea is honored with a statue on Main Street in the small town of Three Forks, MT. Pirsig fans may appreciate that Lewis & Clark named a tributary of the Jefferson River, now known as Willow Creek, "Philosophy River”.

…NOTE1: a) The Jefferson River flow is greatest during a 4-6 week snow melt-off, about mid-May to mid-June. b) One Fishing WebPage says of this river => “The current is usually slow, and irrigation can literally takes a heavy toll on water levels [especially] during drought periods.“ c) My (Henry Gurr) Photos are about June 24, and thus are well after the higher river flows. d) The Lewis and Clark Expedition, the first several days of August 1805, would have seen the river at its lower flow. But the river flow they experienced, could have been considerably greater than the present day, because of no irrigation back then.

What river water my 2002 photos showed, by happenstance, calm water, except for my 2 photos taken within the “Very Steep Walled, Narrow Canyon”.
…Of course, what appears as possibly rapids, may be simply due to the sharp curve of the river making disturbed surface, rather than show a river water speed where are found true rapids. In some of these photos, the water surface shows NO rapids, but only looks slightly disturbed by light wind.

….This is because he discovers and works into the story => How the travel conditions relate metaphorically / poetically to the current Chautauqua Lecture.
….However, in the travel from Three Forks, MT to Hall, MT apparently no such “connections” were found or invented by the Narrator. Although there may be other additional reasons, the Narrator mentions no town name here in the Jefferson Island area. Perhaps the Poincaré topic is too important to withstand an interruption for scenery or anything else.
….There must be powerful reasons, because after Hall, MT, the Narrator again (in continuing the Poincare’ Chautauqua) fails to mention when he and Chris get back on the highway. To my recollection, this is the only place where this kind of “story discontinuity” takes place.

…NOTE: The FOURTH Next Photo Showing => “A High Walled Canyon Near, Jefferson Island, MT”. =>, Has A Link To => A Google Satellite View that is CLOSER-IN on this photo location (Red Pinpoint) where => “The Canyon Is So Narrow, the Road Is Jam Tight Against The High Cliff”. This is on Rt-2 , by Jefferson River near Jefferson Island, MT. This photo hasadditional extensive explanations. What You Need To Know around this area of the Jefferson River.
..****************..

A Note To Prepare The Reader (You) For The Next 23 Photos To Come:
….Just prior to Three Forks, MT, the Narrator, after introducing Poincaré, finishes his 4.5 page Chautauqua on the Three Geometries. Then, per normal practice before he returns to Poincaré, he introduces a half page of Travel Narrative Scenery,which follows the ZMM Passage Italic above =>
…“ East of Butte we go up a long hard grade, cross the Continental Divide, then go down into a valley. Later we pass the great stack of the Anaconda smelter, turn into the town of Anaconda and find a good restaurant with steak and coffee. We go up a long grade that leads to a lake surrounded by pine forests and past some fishermen who push a small boat into the water. Then the road winds down again through the pine forest, and I see by the angle of the sun that the morning is almost ended.
....We pass through Phillipsburg and are off into valley meadows. The head wind becomes more gusty here, so I slow down to fifty-five to lessen it a little. We go through Maxville and by the time we reach Hall are badly in need of a rest. “..
….But this ZMM Narrative is anything but normal! As you will see in next 24 Photos =>
…This half page of ZMM Travel narrative, encompasses => An immense range of scenery, ten towns, 110 miles of travel.
….For me (Henry Gurr ZMM Route Researcher), this ZMM half page, used 8 hours travel & research, during which I took 65 photos and 12 pages of paper notes single spaced.
….I won’t tell you how long it takes me get this same part of my research trip, prepared and uploaded to ZMMQ Gallery, but it well exceeds by five, my corresponding road travel time!
….All of this the Narrator covers in a half page of text!!!

SIDE NOTE:

…. The Previous Photo, The /\ Above /\ Photo and the Next Photos (Each A Stitched Composite of 3 Individual Photos) are all taken at the Same Place along The Jefferson River, which here by happenstance is Flowing East toward Three Forks, MT. . … But Please Remember that the Subsequent 2 Photos showing the ”Canyon Is So Narrow, the Road Is Jam Tight Against The High Cliff”, The river there is flowing ~South.

[The road] “ ….cuts into a narrow canyon of whitish-tan rock, past some Lewis and Clark caves. “

Along The Jefferson River, Approaching “. A Narrow Canyon Of Whitish-Tan Rock ” ~2 Miles SE Of, Jefferson Island, MT. NOTE: Location is not the ZMM Narrator’s.“.At Three Forks . ”, but some 24 straight line miles West & a bit south.,

.... After leaving Three Forks, MT, my paper research notes say } “Cross Jefferson River, and see Junction Rt-287, and start looking for Rt-2. Turn on it, and following upstream this one of three rivers, = The Jefferson”. Later my paper research notes say that I see at this photo location = “A rodeo corral, huge salvaged bridge truss, and Lewis and Clark Caves sign, and ahead, I see the gap where I will be entering (as the river does) the narrow canyon through the mountain ridge.”

..****************..
….The /\ Above /\ Photo Introduces A Geological River Pattern, That You Will See Happens Repeatedly In Montana
….AND Somewhat Happens Here In The Jefferson River.
..****************..
….When Traveling A Long Road, Along A River, Downstream.
.. The river valley traveled, is at first, a terrace which is level and relatively wide, with the river a meandering still water. Ahead you can see the valley land is narrowing, then ends with the road and the river is now descending, in a narrower canyon, with rapids. Where the canyon is narrow, the river & road are relatively rapidly descending, and thus wind down the canyon, until both begin to level out. At this point, they emerge into another level and relatively wide valley land, much like the previous, with the river a meandering still water river!
The Geology Cause?
….It seems that the level, wide valley land, is held that way, against the river erosion, by relatively harder, more durable rock ridge (or rock layer), the drop-down edge of which is called a “Nickpoint”.
….This harder rock is preventing the land from eroding down to the same level as the lower, wide, flat valley terrace next below. Saying it differently, this strong rock has kept the upstream valley land level, and all its beautiful fertile farming, just the way it is.

..****************..
….And Come To Think Of It => What Happens With The Three Rivers, After Three Forks, MT, Is Also A Rather Grand Example Of This!
….These rivers at first are meandering still water, then the valley is narrowing, with the three rivers now forced into one. This is followed by a narrow, deep, steep walled canyon, that is descending in white water rapids.
NEW TOPIC2:
….Because Both Author Robert Pirsig & The ZMM Narrator Hate & Despise “Tourist Attractions”, There Is Absolutely No Hint In ZMM, That => There Is Anything Interesting In Or About These “Lewis & Clark Caves”!
….But the actual Facts are Quite the Opposite!!! Click Here For Wikipedia, Which Has A Great Photo of Stalagmite Limestone Formations Inside The Cavern.
