The Platte or Platteville “M” Mound

Make no mistake about it: people in tiny Platteville, Wisconsin love this Mound. It is definitely the most famous (though not the highest) of the mounds in group of mound complexes you can find in the southwest part of the Driftless Region, simply because the big “M” makes it hard to miss. In fact, the Platte Mound is featured on Platteville postcards you can buy at the Chamber of Commerce (see below). Kip Schreck took this with his Powered Parachute… now tell me that isn’t cool!

Stairs up the mound with names
Two hundred and sixty-six of the stairs leading up to the top of the “M” have been sponsored by “M” aficionados.

But you don’t have to parachute in to get to the top of the “Big M.” Just drive to the base and walk up. Actually, it’s a great way to get in shape, and in summer, you may see the more athletic of visitors running up and down the wooden stairs: almost 300 of them, 266 of which bear the names of the sponsors that helped fund its building. From the top, there’s a spectacular view of the surrounding area.

From the top of the stairs
Almost to the top of 266 stairs. (That’s counting the named ones… a few more have been added at the bottom, as some visitors tended to “slide” down the final bit of the hill if the grass was too wet!)

So… let’s say you’ve pulled into that parking lot at the base of the “M,” and maybe you wonder why it’s there. Well, yeah, you could read the sign, but it won’t help you much… it says “the World’s Largest M” is the symbol for UW-Platteville’s College of Engineering (which would mean it should be an E, maybe?)

But if you have someone with you who’s from around here, maybe they’ll jump in and tell you that the “M” is for “Mining,” because the part of what’s now the University of Wisconsin-Platteville that was an old mining school got into a battle with the Colorado School of Mines to see who could make the biggest “M”… back in the 1930s. But the mining engineers did build it, and current engineering students keep it whitewashed, just like it’s some alphabetic version of Tom Sawyer’s picket fence. In fact, the “M” was until recently part of UW-Platteville’s logo. But all of that is another story, one that winds back through the mining history of Platteville’s recent past. It’s a good story, though not one we’re going to hear today.

Maybe like me, you also wonder what people thought about the Mound before the miners arrived. Surely it was some sort of sacred sight. Did people live on it it? Or maybe you’ve heard stories of UFOs doing fly-bys on the mound… or maybe you just think all this storytelling is just sort of Mickey Mouse.

Guess what? You’re right (at least about the last thing)! On July 4, 1998, the big “M” lit up with Mickey between its peaks (see below). Maybe your guide was part of the Disney Hometown Parade that came to Platteville that year… or maybe they helped whitewash the Mound (especially if your guide is an engineering graduate of UW-Platteville) or danced or played with the band at the annual Miner’s Ball held at its base. Dancing in the twilight of a torch-lit giant letter may be strange, but its a lot of fun.

But for me– not being an engineer, band member, stair runner, or even a good rock whitewasher– the real fun comes from hiking around on top of the Platte Mound and taking pictures. Since every season *but* winter is a good time for hiking, I thought I’d talk about that first, and save the history for another post this winter. So if you want to know more about the Mound’s history… I’ll get to it, but not today.

Seasons on the Mound

If you just want to see the view, summer is definitely the best time. Want to watch a beautiful sunset? The easiest direction to look from the top is west.

Also, if you just want to exercise by running up and down the steps, any time where the temperature’s above freezing will do. (Trust me, you don’t want to run up those stairs when there’s any chance of ice.)

Or… if you’ve read our earlier article on the mound complexes and know how the tallest Blue Mound and Platte Mound and Sherrill Mound all line up, then maybe you want to know how to see Sherrill Mound. (After all, it doesn’t have a big letter on it to make identification easy.) Just look for the two irrigation ponds you see in the photo below, then look up to the horizon. There it is!

Sherril Mound
Here’s another view (with Sherrill Mound in the distance) except its from the base of the Platte Mound rather than the top.
Sherrill Mound in the distance
That’s Sherrill Mound in the distance, on the other side of the Mississippi River.

But if you really want to explore, then take a hike on the top. The best time for that is early fall or late spring, not summer. For one thing, the foliage that grows thick during the summer months includes plenty of stickers and berry bushes–gooseberry and black raspberry, mainly–with thorns. Also, if you like the view, you won’t be able to see much through all the greenery in summer.

Once you climb the stairs to the top, you’ll be facing some ugly cell phone towers (all of the local mounds have cell phone towers on their tops, for obvious reasons–they are the highest spots in the area– though these towers really are eyesores and sometimes give off an annoying hum.)

At the top, you’ll see unlabeled yet pretty obvious paths heading right (south) or left (north). For the shortest and safest hikes, turn right. For more adventure and wilder scenery, turn left.

The Right (South) Path

Mound scenery from south trail
From the south trail looking … of course … south. That’s West Moundview Road in the distance.

The path that heads south will give you a great view of nearby farm country, including several Amish farms which regularly advertise fresh produce through late summer and fall, and fresh eggs year-round. After you wind along the ridge for a very short while, you’ll run into various forks. Don’t worry… you can’t really get lost on this side. If you decide to go off-trail, all you need to do to find that trail again is uphill. If you stay on the gravelly top, you may actually wind up walking on to the cell phone tower service road (which used to be open, but is now locked to keep non-service-people from driving up.)

South view
View from the south end of the Mound.

If you veer off to the right or south side (that is, if you have turned right then turn right again), and if you’re a lot taller and more athletic than I am, you’ll find several places where you can scramble up rocks that have quite an overlook, like this one to the left.

You can also get an idea of how the mounds were formed. Platteville limestone, formed by crushed invertebrates from some ancient sea, is named for this part of Wisconsin. You’ll see layers of this hard-to-erode stone that have been pushed up by even stronger geologic forces.

the old Nodolf house
The old Nodolf residence is the subject of many excellent stories, but it is also structurally unsound. Do not go inside!

Anyway, the south ridge is the easiest to explore if you don’t have a lot of time. If you wind too far down the slope, you could actually be taking an alternate route to the bottom, but I wouldn’t. Yes, those are private residences at the bottom. But there are reasons beyond general respect for privacy that you might want to head back up rather than down.

Time for a little teaser: there’s one backyard in particular you want to be careful of not because of the owners (who are quite nice) but because the house itself is structurally unsound.

You may have heard of it, sometimes called the Platte Mound’s “Haunted House,” or written up in various accounts as the site of the “Nodolf Incident.” That’s yet another story for a different day. For now, our advice is to just stay away! Do not go inside. It isn’t safe. But it’s a fun story for some later cold, winter day… one where the mound liikes like this:

The Platte Mound in winter

We’ll leave hikers with this thought: what if, at the top of the mound, we went left or to the north instead? That’s another whole story! Be back next week with

Caves, Crevices and Campfires: the North End of the Platteville “M” Mound.

[Editor’s note: since the Platte Mound is so heavily associated with Platteville, the most populous city in Grant County, though it’s actually across the county line in Lafayette County, we’ve tagged it for both places.]

The Mounds!

When I moved to southwest Wisconsin 25 years ago, what first struck me were the mounds.  I don’t mean the smaller conical mounds, linear mounds, or effigy mounds, though we’ll road-trip to some of those soon enough. I mean the huge hills that stand out across the landscape to such a degree that if you’re on any ridge in the Driftless Region, you likely can see one of them.

Of course, there’s the ubiquitous Platteville Mound, above and bearing what is supposedly the world’s largest “M.”  But it is only one of a huge and unexplained complex of mounds in the area. While these giant hillsides are natural formations, the “why” behind that formation– just like the “why” that this is the land the glaciers forgot– remains unknown. Most of these large mounds were sacred sites to indigenous peoples.  And most obviously, they are the highest points in the area. 

Charles Mound, Illinois.
Charles Mound, Illinois: it may be one of the least exciting mounds in the area, but it is also the highest natural point in Illinois. Photo by Terry Burns.

For instance, Charles Mound, one of the smaller mounds but one lying in the sliver of the Driftless Region in Illinois, is the highest natural point in that state at 1,235 feet.   (The highest “non-natural” point in Illinois is Chicago’s Willis Tower, at 1,450 feet.)

From almost any ridge in the Driftless area, you can see one of the larger mounds; from the top of every larger mound, you can see a smaller mound. You can actually use the mounds to navigate around the Driftless Region, if you want to. . . and pre-GPS, many people wanted to.

For instance, the sight of one of the smaller mounds, the Belmont Mound (left), is what led settlers to create the first Wisconsin state capitol (right) almost in it’s shadow: the mound was an easy natural marker to find. Legislators actually met in one building (the one on the right) and slept in the other after they finished their business. This ended after a couple of years, when the capitol moved to Madison. Maybe legislators don’t make the best bedfellows!

If you spend as much time as we do road-tripping to different mounds, it’s hard not to start seeing connections between them, which is why I’m writing this introductory post about the “mound complex” rather than individual mounds. For instance, suppose you go to the highest spot in the Driftless Region, the top of the west end of one of the Blue Mounds.

At 1,716 feet, this gorgeous view is also the highest point in southern Wisconsin and the entire Driftless Region.  From the west observation tower of Blue Mound State Park, you get quite a view of some of the other Mounds in the area (as the sign to your left shows.) You can also get an awe-inspiring view of the landscape to the north, or look east and make out the faint outlines of our current state capitol in Madison. (The isthmus upon which our state capitol sits is on yet another sacred site, but that’s a blog post for a different time!)

Some of the mounds on the borders of the Driftless Region, like Elk Mound in northern Wisconsin, actually are made by glacial debris. Many, like the Sherrill Mound over in (surprise) Sherrill, Iowa, aren’t “officially” recognized (whatever that means); others, like the previously mentioned Blue Mound and Belmont Mound (WI) are part of state parks. (Blue Mounds is plural in this sentence but not in the preceding one because only one of the blue mounds is in the state park; there’s a second “Blue Mound,” slightly shorter at 1,490 feet, in a county park nearby.)

Many of the mounds are on private property. Some owners make it clear that you’d better not trespass. Others, like the owners of Charles Mound, let people visit certain times of the year only. In some places, like in Jo Davies county Illinois, home of Horseshoe Mound, a conservation organization has collected money to protect the mound from development.

Sinsinawa signage

The Dominican sisters at Sinsinawa Mound seem unique among mound property owners in recognizing and celebrating that these mounds likely were — or to Dominicans, are — on sacred ground. Sinsinawa’s signage points out that the native Americans who were their when Europeans arrived called it “Manitoumie,” meaning “land where the Spirit dwells,” probably a version of “Manitou.” As author Sister Mary Paynter, OP, pointed out, “It seems that manitou (or a variation) is fairly standard in the languages of native peoples who would have been in this southwest part of Wisconsin at various times– and the meaning is ‘Great Spirit’ or ‘God’ [in our Western Christian vocabulary].” Incidentally, Mary Paynter has done extensive research on the native history of the name “Sinsinawa;” we’ll look at her work more when we road-trip to the Sinsinawa Mound.

Native history in this area goes back nearly 2,000 years and involves multiple tribes, including the Fox, Sauk, Anishinaabe (Ojibwa), Ho-Chunk (Winnebago), Potowatomi, Dakota, and Mesquawki. This writer is not surprised that the lone native reference I can find to what native people called one of the mounds confirms that they saw at least one of them– and my guess would be all of them– as a sacred place.

One might easily guess that the abundance of smaller and definitely human-made mounds (the conical, linear, and effigy mounds which occur throughout Wisconsin but especially in the Wisconsin River valley in greater density than anywhere else in North America, and which make up Effigy Mounds National Monument in Iowa) might be also indirectly related to the lack of glaciers… yet almost all of those were made AFTER the surrounding ice melted. The larger mounds that are the subject of this article are much older: 10,000 years old as a minimum. Some of them, like the smaller mounds, look terraformed. Could they also have been made by native peoples? I’m no geologist, but my friend Dr. Rich Waugh is, so I decided to get the scoop from him. Did humans make these mounds?

The large mounds in southwest Wisconsin, Waugh says, were “most definitely made by natural forces, primarily erosion related to streams and slope processes.”

“None of this precludes human use of the Mound,” Waugh added. ” I would be amazed if Native Americans didn’t impart some meaning to the Mound.”

These huge hills are often pocked with caves and natural springs. They make for great hideaways, too! In my next post, I’ll show you one of my favorites, on the Platte “M” Mound.

Before I end this installment, though, I do want to suggest that these large mounds are more than haphazard markers on the landscape. They’re upwellings of geological energy and follow patterns. As my husband Alan and I road-tripped to more and more of the large mounds, we’ve noticed relations between them not often taught in local schools. 

For instance, Alan noticed that the Blue Mound, Platteville Mound, and Sherrill Mound all line up exactly.

Sherrill Mound (IA), Platteville's "M" Mound (WI) and the first Blue Mound (WI) all lie on the same ley line. Thanks to J. Alan Moore for pointing this out.

From the top of one, one a clear day, you can see the next one. That is, from the top of the Blue Mound’s west observatory tour (as noted in a graphic earlier), you can see the Platte or Platteville Mound (and know that, lined up behind it on the other side of the Mississippi River is the Sherill Mound. From the Platte Mound, you can see the Sherrill Mound. And from the Sherrill Mound (see below) you can see the Platteville Mound (and know that, lined up behind it, is the tallest of the Blue Mounds.

The Blue Mound-Platte Mound-Sherrill Mound line isn’t the only one. Several years ago, conservationists in Jo Davies county Illinois opened up the Horseshoe Mound for viewing.  Clearly the people who designed the new park knew the mound well, and had watched natural phenomena on it for years, because on the top they’ve created a round circle showing where on the horizon the sun rises and sets on the winter and summer solstices. Turns out, the sun sets right between Iowa’s Sherrill and Balltown mounds. To the right, you can see the view with the naked eye, but below is what it looks if you zoom in. We thought it was pretty cool how the conservationists in Jo Davies county set things up so that you have a variety of views labeled, in a sundial-like pavillion.

In the distance, you can see across the Mississippi river to both Sherrill Mound (right) and Balltown, Iowa (which also sits upon a mound.) On the summer solstice, the sun sets right between those two points on the horizon. If the view extended further to the right, you’d also see Sinsinawa Mound, Wisconsin. Photo by Terry Burns.

You can draw similar geographic connections between some of the smaller mounds. And yes, right now I’m mainly writing about the mounds nearest to me… I haven’t moved very far north at all. For instance, so far, I’ve totally ignored the Minnesota Driftless Region, though I will get to that eventually.

But for now, let’s start day-tripping! First stop: the Platte “M” Mound.
