Digging in the Driftless has been exploring environmental topics for almost 5 years. In that time the blog has received over 270,000 views, and I wish each and every one of my visitors Happy Earth Day!
For the benefit of Isthmus readers or others who may be linking in to learn more about Underhill House, I offer an index of posts that cover some of the processes of building listed by topic.

In mid-February, we planted the greens that we expected to transfer to our greenhouse in a few weeks when the cold temperatures subsided, and the weather became a little more mild. (See my post Planting into the Polar Vortex)
As we all now know, warm weather was still many, many weeks away. We had a couple of salads from the thinnings of our seedlings, and moved them throughout the day to get them the maximum sunshine as they grew with gusto in front of our dining room windows.Meanwhile in our unheated greenhouse built against the south side of our barn, we prepped the growing boxes and deployed max/min thermometers. In past years it has been warm enough to transplant into the greenhouse by early March.
The soil temperature began to break the 40 degree mark, but the air was still dropping well below freezing at night.
We read about deep winter greenhouses in Minnesota.
That’s when we got the idea to create a greenhouse within the greenhouse. Many outdoor gardeners make use of row covers. We brought the concept inside, and hoped the sun’s warmth building daily in the soil of the growing boxes could keep plants out of the killer-frost range — so we fashioned a framework and covered the beds with plastic sheeting.
The little darlings have been out in the greenhouse for four days now, and they are thriving. We no longer need the plastic interior cover.
Salad days are just around the corner.
How are your early starts coming?
Doug and I try to eat as locally as possible, and with a year-round farmers’ market in Madison, we are still getting apples, and root vegetables grown last year – even cabbages, which are so much sweeter and more flavorful than anything that has been drenched in petroleum while being hauled from who-knows-where.
Normally we can keep eating local hoop-house spinach all winter long, but this winter defeated the heated hoop houses, and spinach disappeared from the farmers’ market early.
Of course, the most local food comes from your own garden, and we have just had our first home-grown greens of 2014.
We have an unheated, lean-to greenhouse on our barn, and this year the polar vortex is keeping it cold a little longer than usual, but February 8 we planted the last of our spinach and lettuce seeds from the previous season in pots.
February 9 (after a trip to town) we added Italian Heirloom Kale, Parsley, Spearmint, Oregano and Sweet Marjoram to our little table-top garden.
Watching them grow, monitoring their moisture and moving them around the room to keep them in the best possible light has been an entertaining project. Starting seedlings in your kitchen is almost like having a very quiet, fuzzy green pet.
We put about 4 seeds in each pot. A few pots never burst forth, but after 2 weeks, Doug transplanted extras from the successful pots into the empty ones. They are still a little smaller, but coming along.
At first we were misting the surface of each pot every day (more sometimes on sunny days), but once their first leaves unfurled, we started tapering off the water to avoid creating a fungus farm around their delicate and vulnerable stems. Growing them with only available light makes them a wee bit spindly, but everything is a trade-off, and we chose to skip grow lights this year and see what happens.
March 2, we thinned each pot to 2 plants and had our first salad, dressed with a little olive oil, balsamic vinegar and cranberry mustard. Magnifique!
Doug has placed 4 hi-lo thermometers in the greenhouse, two inserted into the soil and 2 just above. Yesterday was sunny, and the air got up to 63 F. The soil temp is only 30, and the nights still go below freezing, so we are waiting for the nights to get a little less intense out there before we replant our little darlings to the greenhouse.
Next up — my best friend and gardening consultant, Susan, tells me it’s time to start onion seedlings for transplanting directly outside.
Do you have a greenhouse or cold frame that you are using to get a jump on spring?
How far along are your greens?
I’d like to share my second article that appeared recently in The Dodgeville Chronicle. I’m covering a 4-part series of evening presentations called “Floods, Droughts, Land and Energy: What Is Wisconsin’s Future.” (Check out the first installment How Will Global Warming Affect Wisconsin.”
“We all have a role to play in how Wisconsin creates and uses energy,” Sherrie Gruder, UW-Extension Sustainable Design Specialist, told an audience who braved another intensely cold night to attend the second of a four-part series on Wisconsin’s future weather and its implications. “How we use energy will play a crucial role in Wisconsin’s economy, environment and public health.”
“We are moving toward a low-carbon economy based on new energy,” she said. “It may not always feel like it, but it is steadily happening all around us. New energy will create jobs and decrease the negative impact that coal-generated power has on our land, water and our health. Burning coal produces a lot of sulfur dioxide, which causes respiratory diseases like asthma. In addition, every lake in Wisconsin has mercury pollution from these coal plants. That’s why we have health advisories that limit the number of fish we should eat – especially pregnant women.”
Wisconsin spends about $19 billion each year on energy, and almost $13 billion of that total leaves the state because we have to buy our power elsewhere.
According to Gruder, what’s needed is a new energy economy in which many people and communities become “prosumers” – not just consuming energy, but producing energy using the sun, wind and biomass. Read More here.
Thanks to the polar vortex,
I have listened to many complaints about below zero temperatures
I’m looking on this winter the way I might have gazed at the buffalo if I could travel back in time and view them from the first railway to cross the U.S.
But today I’m trying not to think about the global warming havoc occurring everywhere we look.
Today I am appreciating this winter gift from the good old days
and simply reveling in its stark beauty –
Plants can’t migrate.
They have to stand there
and take what the weather throws at them.
What are your favorite flowers of winter?
Anyone who lives in or has traveled through the Driftless Area (where Wisconsin, Illinois and Iowa meet) can see at a glance that this is dramatically different from the land encircling it. Because this region was untouched by the last three glaciers, it is defined by rugged ridges and deep valleys that preserve the world here must have all looked like before mile-thick ice sheets flattened the surrounding terrain.
Eric Carson, geologist with the Wisconsin Geological and Natural History Survey does geologic mapping in the Driftless Area of southwestern Wisconsin, and his work in the past year is going to rewrite the natural history of the Wisconsin River. According to Carson, at one time, the Wisconsin River flowed from west to east – the opposite direction of the current current.
A geologic feature, the Military Ridge, runs high and proud, just south of the Wisconsin River bisecting the Driftless region. These days most people know it as a rails-to-trails bike path but it has a long history as a pre-settlement passageway.
In geologic terms, the Ridge is a cuesta, created from cracked and tilted substrata that shoved up a barrier that today creates a regional watershed divide– from which streams north to the Wisconsin and south to the Pecatonica, the Sugar and the Rock.
Up to about a million years ago, the Ridge was enough to turn the flow of the upper Mississippi River to the east at what is now Prairie du Chien along the present-day Wisconsin River bed – it’s waters mixing with Lake Michigan along Door County and eventually disgorging into the Atlantic through the Saint Lawrence Seaway.
Today the Wisconsin River bed gradually drops from east to west. But buried by 50 meters of silt lies the bedrock of the original river that Carson has named the Wyalusing River, and that ancient bed slopes the opposite direction. It’s a case of what is known as “river piracy,”and it’s geology protocol to rename a river whose bed has been stolen.
This information has all been discovered in just the last 8 months!
Carson’s excitement filled the room as he shared his data in a presentation last week at Wednesday Nite at the Lab, “When the Ancient Wisconsin River Flowed East.”
What turned the Wyalusing River around?
A glacier advancing from the northeast blocked the river’s flow, backing up its headwaters and creating a great lake (and that 50 meters of silt). Eventually all that water pouring in burst through, forming a gap in the Military Ridge near Wyalusing State Park. Picture the homes washed away when Lake Delton overflowed in the 2008 flooding see video then multiply it on an inconceivably massive scale.
I am awe struck when I try to visualize geologic events of these proportions!
How Do We Know?
This glimpse of our present world being sculpted by ice and water has been revealed thanks to two new technologies that Carson has been using.
One is a new coring method using Geoprobe coring technology. It’s cheap and fast, compared to previous coring methods. A two-inch barrel is pounded into the ground to establish the top of the bedrock. “It allows multiple holes to be drilled per day, rather than many days per hole,” Carson said. Combining the data from his own boring and the public records from deep-well drilling done for commercial purposes in the state, he was able to clearly chart that the ancient river bed drops to the East.
The second new technology is improvements in LiDAR imagery. LiDAR stands for Light Detection and Ranging. It’s an airborne sensing method that uses a pulsed laser to measure the distance to the earth from a plane. It allows scientists to study the surface of the earth, with a resolution that recently improved from about 1.5 meters to about 5 centimeters. It is giving scientists an amazingly detailed look at the contours of the earth, and allowed Carson to see places where the ancient river bed cut terraces into bedrock near Prairie du Chien, Wauzeka and Muscoda.
Research has also established that the Ohio and other rivers out East had their flows pirated away from Saint Lawrence to toward the Mississippi as well in ancient times. Altogether, Carson estimated these piracies cut the flow of the St. Lawrence into the Atlantic by about a third.
Carson undertook this study as part of a multi-county mapping project that will be used in county planning, but it also may help geologists and climatologists identify the causes of shifts in the prehistoric climate that will help us understand our ongoing global warming in greater detail.
I got a chance to do just that recently when I read in the local newspaper, The Dodgeville Chronicle, about an upcoming 4-part series of evening presentations called “Floods, Droughts, Land and Energy: What Is Wisconsin’s Future.”
We now live about 11 miles from Dodgeville, our county seat, with a population of about 5,000. We subscribe to The Chronicle, but I never thought to write for it before – having spent many years working for big city papers and lately writing mostly for magazines and working on books and my blog.
Doug and I were both excited to see global warming becoming an official topic of conversation in Dodgeville, and he suggested I ask The Chronicle if I could cover the series for them.
So now I’m also a correspondent for The Dodgeville Chronicle!
What is Wisconsin’s Future?
|by Denise ThorntonIowa County needs to be better prepared for natural disasters, cautioned Iowa County Emergency Government Coordinator Keith Hurlbert last Thursday at the first of a four-part educational series, Floods, Droughts, Land and Energy – What is Wisconsin’s Future?
“Think about the storms you’ve seen in the media in the past two years: the tornadoes that hit Joplin Missouri and Alabama, the perfect storm that hit the East Coast and the record-setting storm in Oklahoma City,” Hurlbert said. “These storms are increasing in frequency and growing in size. That’s why climate change is important to me and to all of us. We emergency managers get concerned about how well people in our area are prepared for disaster.”
Hulbert advised that checking the website ready.wi.gov is a great way to learn how to be prepared.
In the event of a disaster, help may take days to reach you, or you might have to evacuate at a moment’s notice. The website offers suggestions of how to create a basic survival kit as well as an evacuation kit of essential belongings and provides a step-by-step Online Family Emergency Planner.
“Climate change is raising the odds of disasters,” Hurlbert said. “How would you handle closed roads and downed power lines? It’s my job to help people think about how to be prepared for disaster.”
“There are both risks and opportunities in climate change,” said David S. Liebl, University of Wisconsin Cooperative Extension Statewide Outreach Educator Specialist. Liebl’s part of the presentation focused on how climate change is going to affect our county.
