Just about a bike: Panasonic Mountain Cat 7500

The way to work
I'm all about taking the long-cut.

I'm a proponent of riding the wrong bike.

And I believe you should do your best to run-what-ya-brung.

Over the years, I've owned many bikes which have equipped me to practice these ideals, utilitarian bikes, which I've always purchased for never-more than fifty-bucks and often less, bikes with big heavy wheels, fewer-than-optimal gears, and often with fenders, racks, and large bags attached.

The world sometimes calls this class of bicycle the "commuter" bike, which is an okay moniker, I guess, if you're after some sort of esoteric differentiation between what this-bike and that-bike can or can't do for you.  But I prefer to just call them all bikes: fat-bikes, cross-bikes, singlespeed-bikes, downhill-bikes, whatever.  They're all fine for getting you from A to B.  They all deserve to be ridden.  They're all fun.

In the end, they're all just bikes.

Nevertheless, of the many utilitarian bikes I've owned over the years, all of which have served me quite well, I've ridden at least three right into the ground, into a condition beyond repair, just because I rode them.  A lot. As in nearly every day: in my youth I thoroughly destroyed an old JCPenney bike that I used for years to deliver the Scottsdale Daily Progress newspaper six days a week; I essentially crushed an old Mongoose ATB which I rode to and from work through the woods for 10 years and which got "the cancer" and broke at one of the rear drop-outs; and I put probably 10,000 just-around-town, back-and-forth, through-the-woods miles on a lovely celeste-colored, Biopace-equipped, lugged Bianchi Incline that was never meant to do such work and which, probably as a result, also got "the cancer" and eventually snapped one of the seat-stays.

The cancer
This 1987 lugged, Prestige-steel Panasonic Mountain Cat 7500, my current go-to, utilitarian "commuter" bike, currently has "the cancer," too, a stress-riser that derives from a breather-hole at the top of the seat-stays.  Not a terminal condition at this point, but ya never know.

Meantime, it's a great bike and has been for many years.

I bought it maybe eight years ago for about forty-bucks at the annual FlagstaffBiking.Org Bike To Work Week bike swap event from my buddy Ken (not that Ken, however) who bought it new in 1987.  At some point along the way, Ken replaced the original stem with a nice Salsa roller-style model.  Otherwise, the bike is in bone-stock-beater condition, sporting mostly period-correct XT components: a U-brake (under the stays), derailleurs, hubs, top-mount shifters, and cranks. I did put a NOS black Hyperlite bar on it, but only because old handlebars make me kinda nervous and I had the Hyperlite in my toolbox.  I also installed a new no-logo, silver 1" Chris King 2Nut headset, but in this case I did so mostly because I had it just sitting in my toolbox, too, not because old headsets make me nervous or something.

The Panasonic hangs on a special "hook" in the garage, set apart from the other "fun" bikes, waiting to be ridden... to work, around town, or on some errand.

The cave

Over the years it's pulled our trail-a-bike and several different trailers, hauled tons of groceries, and transported long sticks of lumber and big bags of dogfood between here and there.  For years, it's taken me to work whenever I needed it to, almost daily, always without fail, and often via the long-cut through the woods: rain, snow, or shine.

It's a super-great bike, still brimming with utility, despite "the cancer" which appears to be growing within.

It's got serious style and harkens fondly back to a long-gone, bygone, exceptionally happy era in mountain biking, when bars were flat and narrow, brakes were cantilevered and often under the chainstays, top tubes were short, stems were long, gears were tall... and the woods were generally less crowded.

All good stuff and worth recollecting, which I do, each and every time I ride it.

Archival Footage: Jimmy


Back around the turn of the century, my then-favorite print magazine, Mountain Gazette, held a "1000 Words" writing contest to see who among their readership could produce the most compelling story with this word-limit as a constraint. I submitted the following work of fiction just before the deadline.  

I got an email reply from the editor, M. John Fayhee, a short time later wherein he stated something to the effect of, "Our editorial board was, in truth, fundamentally split between your story and one other. Yours is a good piece of writing. But in the end they went with the other. Apologies."

I am pleased to report, however that after this rejection, over the course of the next few years, they nevertheless later picked up a few of my photos and also an essay I wrote for publication.

And, some years later, after Mountain Gazette was done as a print mag, Fahyee also used a quote of mine in his book, Colorado Mountain Dogs, too. A fact I discovered only after stumbling quite fortuitously into a author-reading/book-signing he was holding at a small bookstore in Salida, Colorado, a summer ago. He kindly inscribed the book I purchased "to a mountain gazette alumni."

Anyway, for the record, here's my runner-up "1000 Words" short story, adapted from the first few chapters of a heretofore yet unpublished work that I've been slowly pecking away at for years now which still bears the simple title: Jimmy...






Jimmy


Once there was a little boy who dreamt of fire. All sorts of fire: fires that danced in trash barrels and sent flaming-kites and fire-bats high into the nighttime sky… fires that smoldered and ate up the edges of newspaper like the bright orange-red cousins of ants… fires that burnt in treetops and dropped like sun-ripened fruit to the ground… fires that raced wildly across grasslands, erasing the landscape with black charcoal…

His name was Jimmy.

Jimmy first caught fire when he was six, losing two fingers on his left hand in the blaze. It didn't hurt.
It had happened at night.  When he awoke, the smoke alarm in the hallway screaming, a marching-matchstickman dream interrupted, his thick yarn bedspread was smoldering in an aimless, quiet, warm sort of way. 
At the hospital the doctors and nurses were very concerned about Jimmy and they did tests on him and wrapped his injuries carefully with new bandages everyday.  When they took them off, Jimmy saw that where his fingers had been there were now two short, small patches covered with scabby, black and red, wet-looking sores.
One day, while poking at one of the scabby stubby spots and nibbling at some ice cream, a doctor came in and asked Jimmy many questions: “How are you feeling? Do you remember what happened?  Can you feel this?  And this?  Do you have any questions, Jimmy?”
Jimmy had one.  He asked the doctor when his fingers would grow back.  The doctor put his lips close together, closed his eyes some, and shook his head slowly.  He explained to Jimmy that his fingers would never grow back.  
"Fingers just don't do that, I'm afraid," he said.  
Jimmy had expected that was the way things were. He nodded, put his lips close together, and said, "Oh, okay."  
Then he asked for more ice cream.  

The second time Jimmy caught fire, a few months later, the doctors and nurses seemed even more concerned about Jimmy than before.  As soon as he was a little bit better, they wheeled Jimmy’s bed, with Jimmy in it, all over the hospital to meet with new doctors and nurses.  Once they even wheeled him down the sidewalk to a building down the street from the hospital to meet with a doctor there.  All of these doctors and nurses had a lot of questions to ask Jimmy and many of them put needles into his arms and legs.  They tapped on computer screens, gawked at x-rays, and plied Jimmy’s joints back and forth.  
They put him inside big, growling machines.  They put creams and lotions and other greasy things on his skin.  They stuck sticky things to his head.  And, once they stopped asking him questions, they talked about him like he wasn’t in the room or they whispered to one another with their backs turned.
During this hospital stay, Jimmy met most often with a doctor named Crosby. Jimmy liked him; he often brought ice cream, usually enough for both of them.
Jimmy could tell that Dr. Crosby liked him and wanted to find out why he burned.
“I can’t tell you why, Jimmy,” explained the doctor during one of their talks, taking a big bite from the top of his bright orange 50-50 bar before raising the sheet at the foot of the bed to look at Jimmy's leg.  “It’s chemistry, something very unique about you.  We know that, but that’s about all we’ve been able to figure out.”
“So, it’s going to happen again? Probably?”
“Well, if it does, we’ll make sure you’re as protected as we can make you.”
“How?” asked Jimmy, hesitantly; he’d learned to be suspicious of doctor’s ideas.
Dr. Crosby smiled, “Relax.  It’s not going to hurt.  I’ve just got a couple ideas, things that might keep you safer if it does happen again; I heard you did a little damage at home this time.”
“I don’t remember.”
“No, of course you don’t,” said the doctor.
“But you do think I will get on fire again?”
“Jimmy, the honest answer is, I just don’t know.”

Most mornings Jimmy rode a small bus to a special school for special kids, an inviting place filled with children who, like him, dealt with their own unique circumstances each day.
At school, Jimmy was best at make-believe.  He enjoyed melting crayons into wax in one hand by squeezing them tightly for a few moments.  Afterward he would dip the remaining fingers of his other hand into the warm colors and run them across his cheeks, turning himself into an Indian brave, a football player, a raccoon, or just a very odd looking little boy.
His teacher marveled as he watched Jimmy become these characters and he often encouraged Jimmy to tell the class stories based on them.  The other children loved Jimmy’s stories, too. They gave them names and insisted Jimmy tell them over and over again: 
"Tell Applesauce!" they shouted.
"Tell Leyland's Bones!"
"Let's hear Big Bear’s Morning Song!"
"Come on, Jimmy! Tell us a story!"  

But occasionally, during the mid-morning snack, or at lunch, or even right in the middle of story time or make-believe, Jimmy would need to crawl to his special corner of the classroom to wait for the warmth to pass.
If it passed, his teacher would come over and sit next to him on the large yellow fireproof blanket and he would touch a cool wet washcloth to Jimmy's forehead. 
"It's okay, Jimbo.  You're okay this time," his teacher would whisper for no one else but Jimmy to hear. And after a short rest, and a big glass of cold water, Jimmy would return to whatever he had been doing like normal.
But sometimes the warmth wouldn’t pass; it would become hotter.  When this happened Jimmy’s teacher would tell the other children and the grown-ups that helped them that it was time to leave Jimmy alone. 
And then quietly, without any tears, slowly, unrushed by time, in deep blues and dark oranges, tissue-paper-thin mare’s tales of black smoke peering and poking, sneaking out from beneath the red layers and out the white-piped-edges of his flame-resistant jumpsuit, lying atop his yellow fireproof blanket in the corner of his classroom with his eyeballs tipped back and showing only white, 

Jimmy burned.

Archival Footage: The Eastern Sedimentary Block Of Mount Elden

Heart Trail
The following graduate term paper was written and submitted by me "in partial completion of the requirements" for a Geology For Teachers course I took at Northern Arizona University in the summer of 2004, during what is probably best characterized as the second-phase (of four, I think) of  my post-baccalaureate academic career.

I must admit: I was sincerely intrigued by the content of this course. Most likely this is due to the fact that I was fortunate to have had Dr. Larry Middleton as an instructor.  His depth of knowledge and passion for understanding complex geologic processes and structures was truly inspiring to me.  I have continued to be attentive to and interested in geology ever since.  I credit Dr. Middleton (and also my good friend and professional geologist, Joe "Rockman" Hazel) with instilling within me this abiding interest in rocks and stuff.

I got a good grade on this paper, which pleased me immensely, as I put a lot of effort into it.  It's about some of the really interesting non-volcanic, sedimentary geology found on the eastern end of Mount Elden (of which I have written on several other occasions) that's conveniently bisected by the Heart Trail, a trail I ride perhaps once (never more than twice) in any given riding-season.

After I completed this paper, I uploaded it to Wikipedia where it became the initial seed for the site's current Mount Elden entry.

INTRODUCTION
Mount Elden, a.k.a. Elden or Eldon Mountain, located in central Coconino County northeast of Flagstaff, Arizona, takes its name from one of the region’s earliest Anglo settlers, John Elden, who, along with his family, established a homestead on the mountain’s lower slopes and grazed sheep on the open grasslands below during the late 1800s (Cline, 1976).  
Mount Elden
The mountain’s exposed, rocky slopes are a dominant feature from almost any part of the city of Flagstaff, rising steeply nearly 2,400 vertical feet to an elevation of 9,299 feet above sea level.  Much of the vegetation on the southern and southeastern slopes of the mountain was destroyed by a catastrophic 4600-acre human-caused wildfire in June 1977 (Ashworth, 1991).
Despite its rugged appearance, steep relief and massive size, covering nearly 15 square miles of surface area (Kluth 1974), Mount Elden is easily accessible via an extensive, well-developed road and non-motorized trail system.  This paper will concern itself primarily with specific geologic features on the eastern slope of Mount Elden that are accessible via the Mount Elden Lookout Road, the Sunset Trail, and the Heart Trail.

AN OVERVIEW OF THE GEOLOGY OF MOUNT ELDEN
Mount Elden is one of five large peripheral silicic features within the greater San Francisco Mountain volcanic system which include the nearby Dry Lake Hills, the Hochderffer and White Horse Hills to the northwest, and O’Leary Peak to the northeast (Nations, et al, 1986).  Because these features developed within close proximity of the San Francisco Mountain strato-volcano there is a strong likelihood that each is a geologic subsidiary of the larger mountain (Kluth, 1974).
Geologically, Mount Elden is a lava dome comprised almost entirely of dacitic lava flows which emerged from several vents.  According to Kluth these features emerged as intrusive emplacements within sedimentary blocks or as viscous extrusive flows in which the younger flows partially covered the older, lower flows.  Geologic evidence suggests that the eruption of the mountain, which occurred at linear vents along regional faults, was a non-explosive event that took place during several flow sequences.  Likewise, because of the high viscosity of the dacite, it is likely that the mountain formed in the short period of a few month’s time (Kluth, 1974).  The mountain’s overlapping flows commonly take lobe-like shapes which display a variety of flow characteristics and features including concentric benches, spires, ramping shear fractures, longitudinal tension fractures, and conjugate shear fractures. (Nations, et al, 1986).
Occurring within the central part of Mount Elden, on the mountain’s eastern and northwestern flanks are two sedimentary blocks.  Both of these blocks display characteristics of uplift that most likely occurred as dacitic magma intruded into the sedimentary layers at a shallow depth and uplifted the layers causing them to dip away from the mountain (Kluth, 1974).  These blocks of sedimentary material are unique to the mountain, which otherwise is uniformly composed of silicic dacite.  Kluth notes that volcanic material predating the Elden orogeny can be identified among the alluvial material at the base of the eastern sedimentary block.  He also notes that the greater uplift and deformity on the eastern block suggests that there was a greater volume of intrusion emplaced beneath this region.


THE EASTERN SEDIMENTARY BLOCK OF MOUNT ELDEN

The eastern flank of Mount Elden contains the oldest rocks on the mountain.  Due to the intrusion of igneous material, the sedimentary beds of the late Devonian to Permian periods have been thrust upward, overturned, and subsequently have been tipped off the mountain’s side.  This orographic activity, which began during the Tappan Volcanic Period, 0.5-0.03 million years ago (Kluth, 1974), created a large, steeply inclined area of disturbed sedimentary deposits that are predominantly inverted to their standard order of geologic deposition (Figure 1c).
In his dissertation Kluth includes an oblique aerial photograph of the eastern sedimentary block of Mount Elden which includes hand-drawn outlines identifying, generally, the location of the various sedimentary and igneous strata.  Johnson provides a substantially more accurate depiction of this block, adapting an earlier geologic map of Mount Elden originally drawn by Holm (1988).  I have relied extensively on both of these sources in attempting to interpret the geology of the Heart Trail, which generally bisects the eastern sedimentary block. I have combined both of these illustrations to create a generalized cross-section of the eastern sedimentary block (Figure 1c); where these sources do not concur I have attempted to make note of their disparity.
According to Johnson, the Jerome member of the Devonian Martin formation corresponds in geologic character and lithography to the late Devonian Temple Butte formation identified in the Grand Canyon strata (Figure 1c), within which is an exposed horizon of fossilized fish remains.


AN OVERVIEW OF THE HEART TRAIL
The Heart Trail bisects the eastern sedimentary block of Mount Elden generally in an east-west direction.  Originally called the Elden Red Hills Trail, the trail was officially completed and rechristened the Heart Trail in the early 1990s.  Trail construction efforts were spearheaded by Flagstaff residents many years prior (Mangum, 1992).  However, it does not appear to have been in existence in any form at the time of Kluth’s research prior to the publication of his dissertation in 1974.


A PHOTOGRAPHIC TOUR OF THE GEOLOGY OF THE HEART TRAIL
The accompanying photos were taken on August 14, 2004, at various locations on the Heart Trail.

Photo 1
Looking eastward at the top of the ridgeline on Mount Elden, standing on the Sunset Trail on Quarternary dacite.  From this vantage point, several features of the eastern sedimentary block can be observed.  The Heart Trail begins at this point and descends nearly the entire uplifted block, terminating two miles later, approximately 1500 vertical feet below, at the base of the mountain.

Photo 2
Dacite spires above the Martin formation contact looking southeast. Kluth believes that these spires, which appear sporadically at a common elevation across this face of the mountain, were formed at the point of contact between the dacitic material and the sedimentary layers which are found immediately below them.
Photo 2


Photo 3
Sedimentary layers (foreground) below the dacite spires (background) looking westward.  Two distinctly different rock colorations can be seen at this point.  Kluth identifies the initial sedimentary unit in this vicinity as the Jerome member of the Devonian Martin formation. He ascribes to it an olive green to brown color, becoming bleached white where it contacts igneous material.  The material on the left fits this description.  He identifies the next unit as the Mississippian Redwall. In this vicinity he describes it as greyish in color, fitting the material on the right side of this photograph.
Photo 3


Photo 4
Standing in the light colored Devonian-Mississippian Martin-Redwall material looking eastward the contact between these units and the subsequent orange-red Pennsylvanian Supai group below is easy to identify. Kluth notes that the Supai group is identifiable only on this flank of Mount Elden.  Due to fracturing it forms talus slopes instead of cliffs.
Photo 4


Photo 5
According to both Kluth and Johnson, this feature should be located within the Pennsylvanian Supai group.  Here, looking southwest, the bedding planes can be seen to be steeply inclined.  Kluth notes that the uplifted Supai material on the eastern block of Mount Elden dip between 50-70 degrees in a southeasterly direction; this feature would seem to comply.
Photo 5


Photo 6
Looking westward, immediately below the red sandstone of the Pennsylvanian Supai group, there are several small outcroppings of a lithologically different rock.  Kluth and Johnson both indicate the presence of early Permian Hermit shale in this vicinity though Kluth indicates that the shales in this region have not been accurately mapped. Johnson indicates a large deposit of Hermit shale placing it between the Supai group and the Schnebly Hill formation.
Photo 6


Photo 7
A point of contact that appears to correspond with Johnson as the darker red Schnebly Hill formation (left) and buff-colored Coconino-Toroweap (right).  Kluth identifies this vicinity as the boundary between the Supai and undifferentiated Coconino-Toroweap without mentioning the Schnebly Hill formation.  Kluth also identifies the nearby sandstone knobs as the edge of the upturned eastern block.
Photo 7


Photo 8
Looking southwest, below the previous contact the sandstone material is now uniformly buff-colored.  This loose fine-grained material seems to fit with Kluth’s description.  Likewise, Kluth notes that within the Coco-weap exposures the material forms broad flat parks. Here, in its last mile, as the trail begins to traverse less steeply inclined terrain, a mixing of materials, chiefly sandstones, limestones and volcanics, also becomes evident.
Photo 8


Photo 9
Looking southeast at an outcropping of red sandstone immediately adjacent to the trail that appears to correspond to Johnson as an isolated emplacement of the Schnebly Hill formation within the alluvial surface material at the base of the mountain.
Photo 9

Photo 10
Two miles and 1500 vertical feet later, looking west, at the terminus of the Heart Trail.  Here the geologic material is identified by Kluth and Johnson as a mixture of surficial deposits.  The Heart Trail does not appear to cross any sizable, identifiable outcroppings of early Permian Kaibab limestone; however, the presence of such material would appear to be evident in the vicinity, particularly as a major component of the sandy park and small white knob immediately north and east of this position.
Photo 10



CONCLUSION
The eastern sedimentary block of Mount Elden is a unique geologic study area within the San Francisco Mountain volcanic area in Northern Arizona.  However, to date, investigations that have concerned themselves with this region have not benefited from the presence of the Heart Trail, a relatively new route that generally bisects the block, which was constructed during the late 1980s and early 1990s.
Like the Grand Canyon many miles to the north and west, the eastern sedimentary block of Mount Elden contains geologic evidence of the Devonian, Mississippian, Pennsylvanian and Permian geologic periods in addition to ample evidence of both Quarternary and Tertiary volcanics.  However, due to uplift from the intrusion of silicic magma within these sedimentary layers, radical fracturing, tipping and sluffing has occurred, leaving these layers uniformly exposed but inverted to their common order of deposition.

A significant addiction



“May your trails be crooked, winding, lonesome, dangerous, leading to the most amazing view.” -- 
Edward Abbey.




Looking at the last few months of my Instagram and Facebook accounts, I've noticed a theme, and I believe it reveals a significant addiction which I have acquired over the course of many years.

To trails, as seen over the handlebars of a bicycle. And also to the tracks I've left behind.
