12MC is back! Thank you for bearing with me while a took a brief respite from posting new articles. There were logistical reasons. Each race in the five state series took much of the morning, then we’d have to drive to the next location (stopping at geo-oddity sites along the way), arrive late each afternoon, and then start preparing for the next race the following morning. The distances were much farther than my Dust Bowl adventure, and we covered 2,700 miles (4,350 kilometres) in 9 days. Those unfamiliar with the basic outline can reacquaint themselves with our ambitious travel itinerary in The Pitch.
This was the longest break I’ve taken from 12MC in the six-plus years that I’ve been writing it. It felt weird. I had one article in the bag ready to post. It had a rushed and hurried tone without the quality normally befitting this site. So I gave myself permission to take a break. Now I’m able to look at the totality of my Riverboat adventure and organize subjects into themes rather than suffer the disjointed limitations of chronology.
I received several audience sightseeing suggestions both beforehand and along the way. Some of those made it into the narrative and will appear in articles over the next couple of weeks. Enjoy!
The Mississippi and Ohio Rivers Confluence
The Riverboat adventure focused on the Lower Mississippi River, defined as beginning at the confluence of the Mississippi and Ohio Rivers, and extending to the Gulf of Mexico. We didn’t make it all the way to the Gulf although we started at the confluence and made it as far south as northern Louisiana.
We experienced only a single "disappointment" during the entire trip, and I’m almost embarrassed to call it a disappointment because it was so completely trivial. We planned a picnic lunch at Ft. Defiance Park located directly at the confluence. It would have been a lovely vantage point both for its scenery and its geographic significance. It would have offered Illinois’ southernmost point as well as its lowest point of elevation in addition to the awesomeness of the confluence itself. The park was closed because of recent flooding that happens frequently during springtime. Snowmelt flows down from the northern extremes of the Mississippi watershed and overruns the banks in floodplain areas. It was a mess.
Ft. Defiance Park at the Mississippi/Ohio River Confluence
Instead, under the guise of lemons vs. lemonade, we recorded one of the shortest state clips traversed by a 2-digit US Highway. Traveling this route, we crossed from Kentucky into Illinois over the Ohio River, drove through Illinois for a single mile (map) stopping briefly for a few photos — notice the water — and then crossed from Illinois into Missouri. Yes, it would have been nice to have been able to stop there for lunch. It didn’t happen. We salvaged our misfortune by having a perfectly fine picnic at an equally scenic spot a little farther downriver while waiting for the Dorena-Hickman ferry.
Much of Kentucky featured irregular borders (map) defined by rivers or mountain ridges. The Ohio River determined much of its northern and western border. A small portion, however, at the far western extreme of the commonwealth and immediately south of the confluence straddled the Mississippi River. That was our target.
High bluffs protected some of this area so that residents here remained dry while their neighbors in Illinois and Missouri flooded. We stopped at Columbus-Belmont State Park for one of the races. That was the site of a Confederate fortification during the US Civil War, perched atop the bluff in an attempt to control river access and commercial traffic during the conflict.
Farther downstream, Memphis was undoubtedly the largest city we encountered during our journey. We blew through it on our first pass using its highways as a means cross the river and push towards our next destination in rural Arkansas. We would see Memphis again on the return path and stay for a couple of days, and in a bit of foreshadowing, yes we visited Graceland.
Barges heading up- and downstream were a frequent sighting during our journey. Here, a barge passed below the Hernando DeSoto Bridge that carried traffic on Interstate 40 between Memphis, Tennessee and West Memphis, Arkansas.
I’ve driven across the Mississippi River numerous times over the years. However I’ve never driven along the river this far before, not even during my Great River Road trip in Wisconsin. I gained a new appreciation for just how infrequently one can cross the river as we progressed southward down its path, jogging back-and-forth across its banks. One doesn’t comprehend that same sense of rarity on the Interstate highway system where the Mississippi River hardly seemed an obstacle at all.
We used the Greenville Bridge outside of Greenville, Mississippi a couple of times during the drive. We had one race on the immediate western side in Lake Village, Arkansas, and another race just south of Greenville, Mississippi the next day. That provided a rare respite, an uncharacteristic day that involved little driving and some needed downtime.
Lake Chicot, Arkansas
The Arkansas race took place at a beautiful spot along Lake Chicot, the lake for which Lake Village gained its name. Chicot was a classic oxbow lake.
The Oxbow Crescent of Lake Chicot, Arkansas, USA
Wikipedia described it as "the largest oxbow lake in North America and the largest natural lake in Arkansas, formed 600 years ago by the meandering of the Mississippi River." Astute 12MC readers know how much I love oxbows. Largest oxbow in North America! Largest natural lake in Arkansas! Sold. I experienced a genuine geo-oddity simply by watching marathoners loop through the park for a few hours while I went on a photo safari.
Then it started raining like crazy, with thunder and lightning and torrential downpours and the whole deal. This was our day without driving and we knew we were fortunate. I wasn’t disappointed by a rainy day. We were lucky even though the weather sucked, using it as an excuse to hole-up in a warm hotel room for an afternoon to relax.
At this point a special shout-out goes to reader "Bill C." for suggesting the Riverwalk at Mud Island. As the park site explained, "The Riverwalk is an exact scale model of the Lower Mississippi River flowing from its confluence with the Ohio River at Cairo, Illinois 954 miles south to the Gulf of Mexico." I didn’t know about this place in advance and I would have missed it without Bill C.’s suggestion. It was geo-geek paradise, so thanks Bill C.
The Riverwalk represented the entire Lower Mississippi in miniature, everything we’d just spent a full week driving, at a scale where every footstep representing about a mile. I was giddy as I hopped back and forth across the model, pointing out each spot we’d visited during our journey while my wife rolled her eyes and pretended to be amused. This photo captured the Kentucky Bend (aka "Bubbleland") portion, which gave an indication of the model’s colossal scale.
The entire Riverwalk stretched about a half-mile with each concrete layer representing a five-foot elevation change. Notice the color changes, too. The light-tan coloration represented the floodplain. Thus, much of Kentucky Bend would be subject to periodic flooding while the darker-colored area remained dry. Not surprisingly, I noticed that was where the farmers concentrated their homes when we’d visited the Bend earlier in the week.
Signage at the park indicated that the model held about 1.2 million gallons (4.5 million litres) of water at any given time. It was interactive too. Lots of children splashed around in the river and that was perfectly fine. The gift shop even sold T-shirts to that effect.
I’ve been following Every County lately while the author winds his way virtually through, well, every county. He was at the northern end of Michigan’s Lower Peninsula at the time of publication, typing his was down from the Straits of Mackinac. The name Schoolcraft(¹) kept recurring as I read through new installments, a frequent geographic designation in Michigan.
Schoolcraft, for those unfamiliar with Michigan’s history, was Henry Rowe Schoolcraft (1793-1864), a jack-of-all-trades, a geologist, explorer, geographer, politician, ethnologist, writer, publisher, you name it. He wandered within and around many parts of the American Frontier as it was defined in early 19th Century, particularly the Upper-Midwest in Michigan and Minnesota. Consequently, a lot of places in both states bear the Schoolcraft name.
Schoolcraft County, Michigan
Schoolcraft County, Michigan, USA
Schoolcraft County was the largest geographic namesake, an area familiar to Henry Schoolcraft during his lifetime. Michigan established the original Schoolcraft County in 1843, reorganized it in 1871 and established the current boundaries in 1885 as noted in the Newberry Library’s Atlas of Historical County Boundaries for Michigan. The Schoolcraft Chamber of Commerce explained,
In 1832, the "Snowshoe Bishop" Frederic Baraga established a Catholic mission on the eastern shore of Indian Lake. It was also during this time that Henry Rowe Schoolcraft, Michigan’s first Indian Agent and the county’s namesake, was mapping the area, documenting the lives of tribal residence and negotiate treaties. Schoolcraft County was officially organized in 1871, with Manistique designated as the county seat.
I drove through this area a number of years ago on a trip around and across Lake Michigan. I’d love to return someday.

Paradoxically the Village of Schoolcraft wasn’t founded in Schoolcraft County, rather it appeared on Michigan’s Lower Peninsula south of Kalamazoo (map).
The Village of Schoolcraft was the first settlement established in Kalamazoo County. In fact, the original Village was platted in 1831, six years before Michigan became a state… Lucius Lyon, who had settled in the area and who had… been a member of the Cass expedition, as well as a friend of Schoolcraft, decided to name to Village in his honor.
Schoolcraft had also been a member of the 1820 Cass Expedition, named for its leader Lewis Cass who was the Territorial Governor of Michigan. Schoolcraft served as the expedition’s geologist. Think about that for a moment. The governor led an expedition through the wilderness. Imagine the governor of any state today with enough courage and leadership to do something physically demanding, dirty, and even a little dangerous.
Schoolcraft Lake and River
Schoolcraft Lake and River
The Cass Expedition focused on several objectives and motivations, including some scientific. One involved a search for the true source of the Mississippi River in Minnesota. The explorers trekked as far inland as Cass Lake then turned back because water levels were too low for their canoes to paddle any farther in July. The expedition named the lake for its leader, declared Lake Cass the Mississippi source and called it a day.
However that differs from what people understand today, that Lake Itasca was the source. Indeed Cass Lake was many miles downstream from Itasca (map). Schoolcraft suspected the true source laid beyond Lake Cass so he returned in 1832 to finish the job, and then identified Lake Itasca as the headwaters of the mighty river.
There was a tiny Schoolcraft Island on Lake Itasca named in his honor (map)
12MC Walked Across the Mississippi River
It wasn’t very far away from the spot where one could Walk Across the Mississippi River as Twelve Mile Circle did a few years ago. However there was a more significant accolade nearby than the tiny island within Itasca, namely Schoolcraft Lake and River, the first significant tributary of the Mississippi River.

There were several more Schoolcraft tributes although I’ll feature only one more. Schoolcraft College was established in Livonia, Michigan, a suburb of Detroit. I thought it was creative of them to name their dining hall "Henry’s Food Court," a fitting memorial to Henry Schoolcraft.
(¹) I think the name grabbed my attention because it sounded like a version of Minecraft that might be created by an educational institution. Minecraft has become frequent and ubiquitous in our household with our two young boys. It’s all Minecraft all the time in our home.
I’ve been noticing search engine queries lately seeking additional information about points along US Interstate Highways where travelers cross from one time zone into another. I’m going to do that myself soon on my upcoming trip and I couldn’t find a comprehensive resource either. Maybe there’s one out there hidden away in a lonely corner of the Intertubes. Maybe not. I didn’t see it so I decided to create my own. Hopefully others will find this compact reference useful too.
Yes, I understand that mobile phones and other networked devices grab time changes automatically without human intervention from nearby cell towers as one drives merrily down the highway. However some of us like to by hyper-prepared before embarking on a journey. I even recorded the lat/long coordinates so travelers (OK, maybe just me…) could drop the waypoints into their GPS receivers and know exactly where the time change would happen well in advance.
View Interstate Highway Time Zone Changes in a larger map
Readers will want to open this map in another tab or window. It’s not very useful in its present scaled down version that is included for illustrative purposes. Others may prefer the even more detailed Google spreadsheet with links that I prepared. The spreadsheet layout mimicked the geographic footprint of the United States in rough terms, for example I positioned Idaho at the top-left (northwest) and Florida at the bottom-right (southeast). That was also the reason why Interstate numbers on the spreadsheet and the lists below were ordered from large to small (I-94 to I-8). I didn’t reverse the order just to be obstinate. Even-numbered Interstates run roughly west to east across the nation with the 2-digit numbering increasing from south to north. There were also a handful of odd-numbered highways that crossed time zone boundaries too and muddied the construct a bit. Again, the rules applied in general terms only.
This exercise was a lot more tedious than I imagined. Believe me, I’d use much more colorful language if this wasn’t a family-friendly website. I’d assumed quite foolishly that the preponderance of time changes would happen at state borders, and simplify my task. Some do, although many more switch at random county borders which were much more difficult to pinpoint on a map. That’s why I think people have trouble tracking time zones as they drive. Now they have a tool — this page.
Here’s what I found. I’m sure errors or omissions crept into this because it was such a pain to compile. Please let me know and I’ll make corrections.

(1) West Wendover is the only part of Nevada that officially observes Mountain Time, primarily so gamblers from Salt Lake City — the nearest large town — won’t have to deal with a time change and can focus on losing their money without distraction. This was described in (West) Wendover: What Time? What State?
(2) Arizona does not recognize Daylight Saving Time, meaning that for practical purposes the spot where the time zone change takes place shifts in the Spring and the Fall. This can sometimes lead to embarrassing situations.
(3) The exception to the "Arizona doesn’t recognize DST rule" is the portion of the sprawling Navajo Nation that crosses into Arizona. The Navajo did this to assert their sovereignty as well as to keep their tri-state Nation on the same time all year.
(4) Interstate 8 extends from San Diego, California to south-central Arizona; fairly short by interstate standards. Therefore it does not experience a time change when the two states observe the same time (i.e, when the Pacific Time Zone switches to DST and Arizona remains on Mountain Standard Time)
(5) I crossed this one during my Dust Bowl trip. See Kansas Mountain Time.
(6) You’re not seeing things. Interstates 80 and 90 are repeated with the same information here. That’s because they’re co-signed at this spot.
(7) Interstate 85 is the best example of an odd-numbered Interstate messing up my chart. The time change happens at a very southern segment of this very eastern highway.
(8) Interstate 65 starts in Central Time in an Indiana suburb of Chicago, switches to Eastern Time as it heads south, then switches back into Central Time in Kentucky
(9) I included Kentucky parkways because they’re significant roads albeit they’re not Interstate highways (not even Secret Interstates). I probably could have added other roads too.
(10) I will be crossing here on an upcoming trip. This was the spot that inspired me to go ahead and compile the list.
(11) I crossed here in the summer of 2013 during my Kentucky Adventures.
