When you live in a land of lakes, you tend to develop an intimate relationship with wetland geography. Liz passes Theodore Wirth Park on her journey to and from work and sometimes stops to take photographs of one of its hidden gems—the Quaking Bog. The park’s Quaking Bog is a five-acre acid bog where nearly 200 mature tamaracks shade the understory sphagnum moss. Bogs (also known as mires, quagmires, muskegs, and fens) are remnants of the last glacial age. They each develop differently, depending on climate and typography, and often occur when the water at the ground surface is acidic and low in nutrients.

Bogs are often classified based on their location in the landscape and source of water. There are valley bogs, raised bogs, blanket bogs, quaking bogs, and cataract bogs. Quaking bogs develop over a lake or pond, with bog mats (thick layers of vegetation) about three feet thick on top. Quaking bogs bounce when people or animals walk on them, giving them their name. My most vivid memory of walking a bog was a side trip we took on a canoe trip in the Boundary Waters. Here are the impressions of two writers from one of my favorite books on topography, Home Ground: Language for an American Landscape:

The low-lying area saturated with water creates a hollow of decomposed vegetation in wet, spongy ground. This strange land is called a bog, a word that’s been used since about 1450 to refer to such places. The ground sinks underfoot—-collapses, sucks under. It is a netherworld dimly lit, and a rank smell hangs in the air. Yet a bog is far from dead. It supports plant life; as an ecological system, it can be described as a plant community. Cattails, rushes, sedges, and bulrushes are plants that initially creep into a lake and begin to transition that body of water into a bog. The term most often applies to wetlands that have little inflow of water through streams and are fed, instead, mainly by precipitation. What happens is that the plant material growing in the lake dies off and eventually becomes peat. When the dead and dying vegetation rises to the water level of the lake, this accumulation of peat forms a dome, which prohibits any new plants from growing. Without the inflow and outflow of water, a black skin forms, an oily and idle mire locked in a world of its own contrivance. A foot stepping in goes beneath the surface, fast like a thief. Bogs can be found throughout the United States—Web’s Mill Bog, New Jersey, for instance, and Hanging Bog near Cedar Rapids, Iowa. The term bog is also often used in literature to represent the cessation of growth, or a human’s stuck place. In The Red Badge of Courage, Stephen Crane uses a bog to express the conditions of the Civil War. “He is obliged to walk upon bog tufts and watch his feet to keep from the oily mire….The youth went again into the deep thickets. The brushed branches made a noise that drowned the sounds of the cannon. He walked on, going from obscurity into promises of a greater obscurity.”

quaking bog

The quaking bog is one of the most novel features of forests of the northern United States, especially those in New England and Wisconsin. It’s an area of sphagnum moss, rushes, sedges, and decaying vegetation, the whole mass of which is floating on a pool of water. The surface appears solid and stable, until trusted with the weight of a step. What seems to be firm ground then shivers, sinks, and rises, like a natural trampoline or waterbed. If the first shimmy of this rich root mass underfoot is not heeded, one might easily break through the entangled mat into water and loose mud below, as if one had stepped into quicksand. The quaking bog suggests in perceptible human time the larger ripple, rise and fall, and shifting of the Earth’s surface in geologic time.

Vertical Bubble - 1-05-14 - 2

The -22°F drop in air temperature in the Twin Cities this week closed schools and businesses, persuading most of us to stay inside and curl up with a good book. But after seeing the images of photographer Angela Kelly, Liz was inspired to mix up a concoction of soap bubbles, strap her Sony NEX around her neck, and head out into the cold.

I was recruited to blow bubbles, while she chased them around the deck, hoping to grab a quick shot before they flew over the roof and collapsed into tinkling ice crystals. It was -9°F with wind gusts dropping the chill to -30°F below. Liz’s camera even froze up a few times. Yet with everything that was going on around us, she captured a sense of stillness and serenity in these photographs.

Red Dual Bubble - 1-05-14 - 2

After we were back inside, warming our bones in front of the heater, we read up on the details of blowing bubbles in freezing temperatures. Here is what we learned:

1) For the best frozen bubbles, add corn syrup to thicken the water base and increase the surface tension. It is surface tension that allows the solution to form a bubble. Use the ratio of ingredients below. Then mix and let cool.

1 part dish soap
1 part corn syrup
6 parts hot water

2) Use a bubble wand, instead of your breath.

A bubble is formed by a layer of water molecules trapped between two fine layers of soap molecules. When it is very cold, and the bubble wand is waved slowly, the water layer freezes before the bubble can burst. By contrast, if you make a bubble by blowing into the wand, the bubble takes more time to set because the air in the bubble has been warmed by your lungs. When this warm air comes into contact with cold air it contracts, and the surface of the bubble sets more slowly.

3) It’s natural for frozen bubbles to collapse into themselves.

The layers of soap freeze, making the walls of the bubble more solid. After a few seconds, the air captured inside the bubble disperses to the exterior, like a balloon deflating, and the wall of ice collapses under its own weight leaving what looks like a broken eggshell.

We are counting on Minnesota to produce another round of sub-zero temperatures (and less wind) so we have a chance to practice more frozen bubble photography before spring.
