As you'll see, the story of the Ottaway is told through the hearts of minds of over 30 various stakeholders, as they confront the challenges of turning back the hands of time by removing the three upper dams and modifying a fourth to once again connecting the region’s major coldwater river with the waters of Lake Michigan. This film weaves together strong Native American values, the complexity of a changing society, and the unspoken voices of nature’s population of “environmental citizens” whose lives are interwoven with… the rebirth of the Ottaway.
With funding support from the Grand Traverse Band of the Ottawa and Chippewa Indians, this documentary film also offers a blueprint on how communities across Michigan can navigate the challenges of dealing with the state’s 2500 outdated dams that face similar fates as those near Traverse City.
Over two years in the making, this film was produced by Dan Bertalan, an Emmy-winning documentary producer with deep roots in Michigan and environmental justice. This film recently won an Emmy from the Michigan Chapter of the National Academy of Television Arts & Sciences. The film was broadcast via CMU Public Television and public television affiliates across Michigan. Also, the Outdoor Writer’s Association of America awarded the film honors as the top Conservation Documentary in their national awards.
Plans are already underway for a sequel documentary as the final chapter of the river unfolds with the building of a state-of-the-art selective fish passage that will once again connect spawning fish from the Great Lakes with historic waters they haven’t been able to reach in over 100 years.
If you could have flown over North American in 1492 (when Columbus sailed the ocean blue and discovered America) you would have seen a vast wilderness, unbroken by the sweeping hand of civilization. And if you could have somehow counted all the white-tailed deer within the forests then, their numbers would have totaled about 45 million.
Now if you jumped ahead in time some 400 years to 1903 when the first plane did actually fly over Kitty Hawk, North Carolina by Wilbur and Orville Wright, you’d see that the landscape had changed dramatically. Settlers with their axes and plows had transformed many of the lush forests into farms. Settlers’ guns combined with uncontrolled market hunting had also dramatically impacted those 45 million white-tailed deer. In fact, they had been decimated to the point of only an estimated 300,000 deer in the United States by 1903. With such a downward spiral, they seemed doomed to near extinction, right?
But thanks to the birth and evolution of modern wildlife management, things changed dramatically for the white-tailed deer. Now there are about 100 times more deer, some 30 MILLION that now inhabit North America. Think about that for a moment… 100 times more deer than 100 years ago. And today, the “whitetail”, as many people call them, represent the nation’s most abundant wild game resource and one of America’s great conservation success stories… all rolled into one.
All that sounds pretty wonderful on the surface. But with that many deer sharing a limited or shrinking wild landscape with some 300 million humans creates a whole set of serious challenges for wildlife managers, public safety officials and the other species that share those limited wild places. Two reasons that whitetails have been so successful in rebounding their numbers are: 1) they are extremely adaptable to almost any wild or human-made environment, 2) they are a “keystone” species - which means they can dominate and eat so much plant matter in an ecosystem that they can adversely impact all the other species that try to share that ecosystem.

The first major step (shown in another video) in refining crude oil is fractional distillation where they heat the crude and literally “boil off” the different hydrocarbon chains. This causes the vertical separation of the different hydrocarbon molecules in the tower.
But because fractional distillation only produces about 20% gasoline from the crude, petroleum engineers get techy by using some sophisticated combinations of physic and chemistry in a process called "cracking”.
Cracking is the process of breaking apart longer hydrocarbon molecular chains into smaller pieces. The process breaks or cracks the heavier, higher boiling-point petroleum fractions into more valuable products such as gasoline and diesel fuel. Though that may sound simple, it’s far from it. In fact, they use several different sophisticated methods of cracking hydrocarbon molecules in a modern refinery.
The first is thermal cracking that they do inside a unit called a “coker” where they subject the hydrocarbons to extreme heat and pressure. Coking is a severe method of thermal cracking used to upgrade heavy residuals into lighter products or distillates. Coking produces straight-run gasoline (naphtha) and various middle-distillate fractions used as catalytic cracking feedstock. The process so completely reduces hydrogen that the residue is a form of carbon called "coke." 
Another form of cracking is hydrocracking. A hydrocracking unit, or hydrocracker, takes heavier and higher boiling range molecules and cracks the heavy molecules into distillate and gasoline using hydrogen and a catalyst.

Sometimes, we think that the food we eat just pops out of the ground or appears magically at our supermarkets, but the truth is much different. Jacob and Gianna, our hosts, quickly discover that a huge amount of work goes into growing soybeans, and that the most sustainable ways of doing things are not always the easiest. That being said, it does not take long for them to learn that sustainable practices often equate with financial success for farmers and others in the soybean industry.
Sustainability has three pillars: environmental, economic, and social. Each is equally important, and they combine to paint a bright picture for the future of the soybean industry. The hosts enlist the help of Cedric in mission control and Coolbean, a smart soybean with an ego to match, to find the base of each pillar and get the big picture of what these pillars support.
The hosts start their journey into soybean sustainability from the ground up…literally. A farmer explains the sustainable practices he uses on his farm and a soil scientist describes the process of soil testing. Why would scientists go through the trouble of digging up dirt all over a soybean farm? And what scientific process makes soybeans one of the best crops to grow in the Midwest? The hosts, and experts that they speak to, will help you answer those questions and many others.
All this sustainability stuff may seem like a lot of extra work and, well, it is. As another farmer explains, however, this extra work results in extra income for the farmer. How else are sustainable practices involved with soybean economics? The hosts wonder what happens after soybeans leave the farm and quickly realize that sustainability plays a part in the transport of soybeans as well. A grain distributor highlights how a cooperative saves farmers from driving hundreds of miles while a lock-master (huh, what’s that?) describes barge transport. It turns out that one barge traveling down the Mississippi River contains as many soybeans as 58 trucks. Whoa.
Ok, so soybeans benefit the environment and farmers, but aren’t there three pillars of sustainability? What about social sustainability? A farmer walks the hosts through her family farm that benefits the environment, economy, and her community all at the same time. Next, a nearby town beckons. Two kind community members tell the story of how Evansville, Wisconsin became the “Soybean Capital" of the state. Finally, they learn about a group of farmers that work together to minimize erosion from their farms into the watershed of Madison, Wisconsin. Here are three different methods with one common goal.
Sustainability has not always been the top priority of the soybean industry. One of the experts the hosts speak to was instrumental in developing the National Soybean Sustainability Initiative. This tests how sustainable farmers and others in the industry are being, and provides them with ideas on how to do even more in the future. This came at a perfect time, as the hosts realize by talking to an employee at The DeLong Company. These days, soybean buyers all around the world demand soybeans produced sustainably. The market must meet this demand but the push towards being more sustainable has benefitted the industry tremendously and the hosts find out why. You will too as you watch this episode. Just promise that you won’t be a know-it-all like Coolbean....
Life lesson here. What's the impact on the planet and society when a user of natural resources only takes resources for profit and fails to reinvest in restoring what they've impacted? Everyone loses. The planet, society, ecosystems and even the company end up being losers. What's the solution? For an industrial sand mining operation it begins with a comprehensive environmental study that becomes part of their mine reclamation plan that should consider all the abiotic and biotic factors that may be impacted by mining.
When done right, a mining operation is actively going through several stages of evolution and transformation. At Tunnel City, Wisconsin for instance, they didn't simply come in and bulldoze off the overburden from the entire area so they could scoop up all the quality sand and leave a giant gaping hole in the ground. No, that would be totally wrong for the environment and nearby communities. Instead, they mine across the landscape by mining sand in one smaller area while restoring previously mined sections in different areas at the same time. So they're essentially reclaiming and restoring some areas while they're also mining the sand from new ones. The end result is that there's less total cumulative impact on the greater landscape and the various species that live there.
We can imagine how a white-tailed deer or wild turkey could easily flee the advance of mining in a certain area and return months or years later when the area was restored. But what about special species that depend on a key part of the environment, or what if a species is special or endangered? That too is part of a proper environmental study that's incorporated into the restoration plan. Watch the video here and read more in the "Learn More" section below to discover how certain species deserve special attention during planning and restoration.

Let's say that you have a super-sub sandwich with tons of meats, cheese, lettuce, tomatoes, and the works all layered together. Your challenge is to "mine" out one select layer of ham, sandwiched in the middle, by pinching out finger-sized bits from above and below. And after you've removed all the ham, you somehow have to put the sandwich all back together so it looks the same (minus the ham) as before you started. Impossible? With a sandwich, maybe it is. But how do industrial sand miners do something very similar on hundreds of acres of landscape? The answer is that they use a "geomorphic mine reclamation plan".
As you'll see in the video here, mining industrial sand isn't as easy as scooping up loads of the stuff off the ground. Mother Nature and the unique geology that created industrial sand layers make it challenging and a bit complicated. Take, for instance, the industrial quality sandstone zone in the open mine at Tunnel City, Wisconsin. It's like the ham in your sub sandwich as it's sandwiched in the middle and covered with tons of "overburden" that need to be dug and hauled off bit by bit using bulldozers, front end loaders, and huge trucks.
Mother Nature did smile on the miners here, however, as the prime sandstone layer is not cemented very much between the grains. Many ancient sandstone layers undergo the geologic process of "secondary cementation" where mineral-rich waters in the formation precipitate various forms of calcite or silica over time and cement all the individual grains together into a massive block of sandstone. Sure, it makes really solid material for building pyramids, but also makes it almost impossible to mine for the industrial sand that must consist of loose and clean individual grains.
Once they expose the quality zone of sandstone, they can extract it with big D-11 bulldozers and front end loaders. No blasting needed here. You can almost break the sandstone apart with your bare hands. However, moving tons of loose sand with all that machinery has the potential to create a health hazard. It's called silica dust that can, in some instances, cause a lung condition called silicosis. Click on the Learn More tab below to learn more about the kinds of potential silica dust and how miners control and monitor it.

Ah, so you already "know" that mining and using frac sand, or "industrial sand", is a bad deal, right? Before you answer, consider where you learned that. You may have formed your opinion from biased sources that presented a negative image because it made for more controversial news or supported a particular perspective. A skewed perspective can sometimes speak in a stronger voice than factual science.
That's why we want you to become real scientists here by forming your own conclusions based on the facts that you discover. That is an important part of the scientific process. Do your own independent research such as digging into the science here, the links at the bottom of this page, and within other recent scientific studies and different online sources. You may be surprised by what you uncover.
The chemistry and geology of industrial sand in the Upper Midwest is relatively simple and very ancient. Sand is made up primarily of quartz. It's silica, or SiO2. It's the most common silica crystal and the second most common mineral on the earth. And because of its chemical and physical properties, it's key in making many of things that make our modern lives possible. Rather than simply tell you, watch the video above to get a better idea. Doing your own online research will reveal even more uses.
But why mine industrial sand when deserts and beaches are covered with tons of sand? The answer is that different kinds of sand have different chemical and physical properties. To be classified as industrial sand, the sand source needs to contain a large percentage of very pure silica sand, with uniform grain size and clean, well-rounded grains. The silicon-oxygen atoms that make up pure silica quartz form one of nature’s hardest minerals. One of the geologic factors that created sedimentary layers of industrial-quality sandstone is that the sand was "washed and sorted" for millions of years in an ancient sea by tides, currents, wave action, and storms. Most of the impurities got washed away while the sand grains became extremely rounded and sorted into very uniform spheres. In some of the sandstone layers they almost resemble clusters of miniature eggs.
This rare silica sand layer of sedimentary rock was deposited in an ancient sea 500 million years ago that used to be located in parts of Wisconsin, Minnesota, and Illinois. Because this particular sandstone layer is only exposed at or near the surface in some places, it makes certain sites in Wisconsin and Minnesota very important to the sand mining industry.

Have you ever wondered where the fuels that power our vehicles comes from? Or, have you thought about how they turn syrupy black crude into the clear gasoline and fuels that drive our society? Well, ponder no more. You're about to get a serious introduction to the science and technology of refining and transporting hydrocarbons.
There are two ways to learn here: You can simply watch this "Emmy-winning" video above or read more of the background information below. Doing both can double-up on your smart meter. As a side note, the National Academy of Television Arts & Sciences was so impressed with this production, that they awarded it with the Emmy for the top Youth Educational Program-Series in the Midwest. Woo-who! A big shout-out to our ITO youth scientists shown here with their well-deserved Emmy at the awards ceremony in Chicago. See the video to the right.
Before we get started however, let's consider your previous knowledge base about the petroleum industry. Chances are you've likely "learned" more about the oil industry from the news than from hard science sources. One of the rules of being a scientist is knowing how to evaluate potential bias of your information sources (including us). And news by it's very nature focuses on negative events cast in extreme situations. So it's little surprise that the news about the oil industry is sometimes presented in a negative light. Oil spills make for dramatic news stories, yet we seldom if ever hear about how the industry plays a vital role in powering almost every segment of our industrial society. Without it, we'd pretty much grind to a halt. Consider that as you begin "refining" your own critical thinking by exploring the science and technology here that begins to decode refining and transporting the fuels that make our modern lives possible.
Let's start by digging into the science behind the formation of crude oil. Did you know that crude oil was formed from the decomposed body parts of ancient marine organisms? We're talking real tiny stuff here like algae and other microscopic organisms such as zooplankton. Nope, there's no dinosaur juice or ancient forests in that formed oil.
One of the keys to this ancient marine life eventually becoming oil is being trapped in a sediment layer. This layer also had to be free from oxygen in an “anaerobic” environment to prevent scavengers from eating them. As more accumulating sediment layers buried their body parts deeper, pressure and heat essentially “cooked” their organic matter into hydrocarbons. And that's how crude oil was formed. Despite the common misconception, an "oil reservoir" in the ground isn't a giant cave in the earth filled with oil. Instead, the oil in a reservoir rock is located in the tiny interconnected pore spaces in the rock. In fact, some rocks such as sandstone, can have up to 30% porosity, or interconnected pores spaces for oil to occupy and flow through. See for yourself sometime by filling a cup with sand, then slowly pouring about a half cup of water into it before it overflows. The water seeped into the 50% "porosity".
Once a reservoir is drilled into and the crude produced, it needs to be refined. Crude oil straight from a well by itself isn't useful for much of anything. Oh sure, it will burn, or mess up your clothes. But it sure won't fly a jet or run in your vehicle. Rather than try to explain the whole process, you're better off watching the video above as you join our science team as they explore the entire process at Pine Bend Refinery, one of the most complex refineries in North America. As you'll see in the video, with the help of Flint Hills Resources engineers, they reveal the chemistry behind crude oil and touch on why it's vital to so many aspects of our lives.
As you'll see, one of the early phases of refining is the process of "fractional distillation" where they "cook" off the various hydrocarbon fuel "fractions". Yeah, it sounds confusing. But watch the video for a refined picture of how it all works. You’ll also get to see how the refinery’s very own version of mission control operates this complex refinery that's the size of a small city. You'll also learn how refinery experts use physics and technology in the refining process to remove impurities such as sulfur. They also use combinations of catalysts along with heat and pressure to enhance chemical reactions.
What do Legos have in common with oil refining? As you'll see in the video, they help conceptualize the refining process of “cracking” longer, heavier hydrocarbon chains of molecules into shorter chains that make up various fuels such as gasoline and jet fuel.
As you'll also see, it's pretty hard not to notice the steam coming out of some of the refinery towers. We know that steam comes from water and that fresh water is a precious resource. So our hosts also live up to their name of Into the Outdoors by getting to the bottom of how Flint Hills Resources manages, recycles and protects the water resources they use.
All these refined fuels eventually need to get from the refinery to the industries and businesses that use them, right? We sure can fill up our cars at the refinery. So pipelines offer the safest and most reliable method of transporting those fuels to all the various distribution points in society. That's why our team decodes all the pipeline connections, with the help of various engineers while exploring the physics behind transporting fuels via pipelines. Because pipelines span huge distances across all kinds of environments, our video team also digs into the technology engineers use to monitor pipeline integrity to prevent leaks and how they repair pipelines that need attention.

When you think about mining, you probably think about minerals like gold, diamonds, or copper. But sand? What is so special about the sand deposits in Wisconsin and why has the sand mining industry grown so tremendously here in the Upper Midwest? Put on your hard hat and let’s decode the science of the frac-sand industry.
Why is all this sand in the Upper Midwest and what is the sand being used for? The first section of the video will help you solve those mysteries and more. The quartz sand mined in Wisconsin is especially pure due to its position at the shoreline of ancient seas. Waves pummeled the sand for millions of years, cleaning it of impurities and causing each grain to take on a rounded texture. Only clear, rounded sand grains can be processed by the mining company and sold for a variety of uses. What is this sand
used for? Watch the video to find out.
The second section of the video explores how the sand is actually mined. The investigative team finds out how sand is accessed and transported by interviewing a mining expert. Cedric, back at mission control, is not satisfied. He requests that the team asks a tough question about airborne sand that can cause a serious medical condition called silicosis. Emma and Josh ask experts about what Unimin does to keep their employees and surrounding communities safe from this dust, as well as manage the water they use in their operations.
The resident scientist at Unimin explains the process of reclamation in segment three. Reclamation means taking land that has been altered and managing it to match what it was like before mining took place. Unimin reclaims as they mine. They analyze the land before they ever dig so that they can recreate the original topography when mining is complete. Bulldozers move topsoil to areas in need of reclamation and workers plant native seeds to match the original habitat.
Segment four highlights the story of a species that has benefitted from Unimin’s sand mining operation. The Karner Blue Butterfly is an endangered species that prefers sandy soils with healthy populations of a beautiful purple flower called lupine. Unimin planted lupine throughout the areas it reclaimed and scientists have observed higher numbers of this small butterfly after reclamation compared to surveys conducted before mining started.
The investigative team has one final task in segment four. They need to ask critical questions about the impact of the sand mine on the local community. Josh and Emma sit around a bonfire with local kids who discuss their thoughts on the sand mine. Perhaps, like the kids, you’ll come up with your own conclusions about sand mining after watching the video below.

What are these strange things called “Ice Caves”?
It all began hundreds of millions of years ago when sands were washed into an ancient ocean, forming bedded sandstone rock layers across Northern Wisconsin. Much later, the area was “geologically uplifted” and exposed the massive sandstone layers to the erosional effects of weathering from waves and water.
To learn more about the rocks along the shores of the Great Lakes, download the free lesson activities at the bottom of this page.
Now back to the ice caves…. Over time, the powerful forces of wave erosion along the shoreline of Lake Superior carved sea caves along the Mainland Unit of Apostle Islands National Lakeshore. Where wave action erodes and undercuts the base of a cliff, a feature known as a “reentrant” develops. Sea caves are produced when a number of these reentrants join behind the face of a cliff, leaving behind supporting pillars and arches. They develop most easily where the sand layers comprising a rock formation are very thin.
The sandstone bluffs that border the lakeshore there make for an ideal setting for the formation of ice caves – when winter weather conditions are right. Each winter ice forms on Lake Superior when waves splashing against the rock face begin to freeze on the sandstone cliffs. The more frigid the weather, the faster the ice forms along the rock bluffs and within the eroded caverns. Adding to the ice formations, water seeping between cracks in the sandstone rock layers freezes and forms a variety of features similar to limestone caves. But here, the stalactites and stalagmites are made of ice. Iron leached from the rocks can stain some of the ice formations pink or orange. While some formations with water splashing from the crystalline waters of Lake Superior can appear “ice blue”. There are also large icicles and formations hanging off of the cliffs that form curtains and columns of ice, and abundant ice crystals.
Before planning a summer paddling or “ice cave” winter trekking trip to the area, check the websites below to find out conditions and safety concerns.
