We climbed to the very top of the tallest dune in the area, to get a better view of the ice on Lake Michigan. The ice stretches for miles along the shore, but what proved to be more interesting was the view up. A deep blue sky and trees reaching for it, kept me entertained as the kids jumped around the snow on the dune.
It's March, and the days are warming a bit- that means the sap is running! It's Maple Sugar Time. Maple sap begins to run when the daytime temperatures are above freezing, and the night temperatures drop below freezing.
Walking around the Chelberg Farm this time of year, one gets a sense of how things were in the 1930's, when the Chelberg's began gathering sap to make maple syrup to sell in Chicago. The woods were full of maple trees, and with a bit of hard work, the sap could be gathered, refined, and sold for a late winter profit.
Maple syrup is strictly a North American product. More specifically, it's naturally limited to the region east of the Mississippi River, north of the Ohio River, and into Canada.
The process has been modernized, but syrup making began with the native Americans. They placed hot rocks into wooden bowls filled with sap. The water boiled out and what remained was pure maple syrup. Today, in commercial syrup production, plastic pipes and stainless steel evaporators are used to gather and reduce the sap.
The Indiana Dunes National Lakeshore's Chelberg Farm demonstrates the maple sugaring process each March during Maple Sugar Days. They explain and demonstrate how the native Americans refined the sap, as well as the more modern, 1930's methods.
Still using galvanized buckets hung from cast spiles, they gather sap from numerous sugar maple trees on the property. The sap is then transferred to the the original "sugar shack" where it is warmed over a wood-fired evaporator. It takes 40 gallons of sap to make one gallon of syrup.
An interesting thing to note is the glass jug hanging over the evaporator. Being March, it's rather cold outside, and in the sugar shack. Pouring hot maple syrup into a cold glass jug will cause the jug to shatter instantly. Heating the jug above the evaporator makes the glass warm enough to prevent it from breaking.
Unfortunately, they can't sell the syrup they produce, but it's certainly worth a trip to the national park to watch the process.
One of the great things about the winter at the Indiana Dunes National Lakeshore -aside from the ice formations - is the fact that you're almost always alone. Occasionally we see others, but it's rare. And quite often, when I visit by myself, I don't see anyone for miles around.
Summers are usually very busy, but when I arrive before 7am, I'm also alone, watching nature wake up to another day.
Looking a lot more like the Arctic Ocean, Lake Michigan has its share of drift ice this year. While it appears to be quite solid, the drift ice is comprised of small pieces of ice "drifting" along on the surface of the lake. It's difficult to see, but a time-lapse image would show movement in almost every direction.
Apparently, the winds have been blowing from the Northwest, pushing all the ice toward the southeastern shore of the Great Lake.
It may not look like it, but this is the shore of Lake Michigan. The person walking is safe, right on the shore where the waves break in warmer weather. Cold water and waves create these mounds of shelf ice; this year, they extended hundreds of feet into the lake. Tempting hills to climb, but they can be deadly, so it's never a good idea to wander out onto them.
With Lake effect snow expected all weekend, I opened the window to check how much snow fell over night. At 5 am, not only was there no snow, but the stars were out. I headed outside with the camera and tripod to capture images of the stars.
In this 5 second exposure, the approaching lake effect snow can be seen on the horizon. By 6:30 am, the snow was falling.
Generally, following a hike down into the canyons of Matthiessen State Park's upper dell area, I'm confronted by a silky waterfall, or a frozen waterfall. While the waterfall was partially frozen, I was captivated more by the view up.
The arched, concrete pedestrian bridge and the bare trees silhouetted against a partly cloudy sky, mattered more to me than another photo of the waterfall.
Each winter, I dedicate a good portion of my photography to ice and snow. I really don't like cold weather, but for some reason, when I'm out photographing the frozen lakeshore, I don't mind so much. Along with the beauty of the ice, comes a lot of danger. It's easy to forget that these huge mounds of ice are deadly - very deadly. In between the 15 foot thick mounds of ice are dangerous holes - some leading directly to the deep, frigid waters below.
These holes are often covered over by loose, drifted snow or a paper-thin layer of ice. One step and you're in Lake Michigan - 33 degree Lake Michigan, with no way out. It's similar to falling into an open sewer, except there's no ladder to help you out, and you are pushed around under water by the wave action, so you don't pop up where you fell in.
In the photo here, Mike stands near one such hole. This one was easy to see, plus it was formed by waves crashing onto the beach, so it was not over water. Just a few feet to his right is the waterline of Lake Michigan, and the shelf ice continues for hundreds of feet off shore. The water is over 10 feet deep a few yards out, making it impossible for anyone to stand up and attempt to climb out. Besides, the sides of the shaft leading to the surface is slippery ice, and the water is so cold, muscles don't work.
If you're out near Lake Michigan in the winter, resist the temptation to walk on the shelf ice - it's much more beautiful from the top of the dunes, than from the bottom of the lake.

Standing (safely) on the first mound of shelf ice. I say "safely" because I know the beach is underneath me, not cold Lake Michigan. If I were to venture any further to the right, I would be standing on ice that formed over water, and was only connected to the shore at the surface - like a shelf; hence the term "shelf ice."
Barely visible are two people walking down the beach - they certainly give some scale to the amount of ice here at the shore. It extends hundreds of feet out into Lake Michigan. The wind and waves kick up the floating drift ice, it piles up near the shore in mounds over 15 feet tall. Then a calm period follows where more drift ice forms, followed by another windy day of ice piling up, and so on. This creates the series of ice mounds seen here.
Shelf ice lines the beach of the Indiana Dunes National Lakeshore. Weeks of cold weather, and high waves have mounded up ice over 15 feet high, and hundreds of feet into Lake Michigan. These thick ice mounds are often peppered with paper-thin covered holes leading directly into the 34 degree lake below. As inviting as it may seem to walk out onto them, it may the your last hike. The ice is attached to the shore, but not the bottom, thus the name "shelf ice." It often breaks off and rolls into the cold lake, creating a dangerous environment for people.
Two people walk along the shore, looking for a place for sledding. It's prohibited in the National Lakeshore.
At the "end" of our canyon walk, two waterfalls empty into the creek. In winter, they generally freeze into solid columns of ice. This one has just started to form a column, and the indent in the canyon wall provides a great place to crawl into to view the back-lit ice.
The ceiling of the cave is about 15 feet above the ground, and the column of ice is about 8 feet wide.
