The Driftless Slope Map that I created in 2013 is now available for sale from the nonprofit Crawford Stewardship Project. Both posters and postcards are available. Purchases support environmental sustainability in Crawford County, Wisconsin, at the heart of the Driftless Area.
Crawford Stewardship Project works to protect Crawford County and neighboring regions from threats of polluting and extractive industries, to promote sustainable land use, environmental justice, and local control of natural resources.
Crawford Stewardship Project mission statement
The Crawford Stewardship Project is an independent 501(c)3 nonprofit and I receive no royalties or fees from their merchandise sales.
Comet C/2020 F3 NEOWISE, discovered only a few months ago, is now putting on a marvelous show in the northern sky.
I went out last week with a 55mm F1.8 lens to capture some obligatory comet photos and then turned my camera on a few other highlights of the July 2020 evening sky over Wisconsin. Click on a picture to expand it.
Wisconsin is better known for trees, cows, and snow than for cactus. Even so, multiple species of prickly pears have a native range extending to the Upper Midwest. The cacti are not abundant, but they can flourish in the micro-climates created by well drained, sunny slopes in the Driftless Area.
These wild prickly pear cacti grow along a south facing outcrop of St. Peter sandstone in southwest Wisconsin. I was lucky enough to find them just in time for their short lived yellow blossoms in early July.
While shops, schools, and museums shut down for safety from March to May amid the COVID-19 Pandemic, the woods of Driftless Wisconsin came alive in their usual burst of spring color. This photo gallery looks back at the emergence of spring wildflowers week-by-week.
For another perspective on spring in the Driftless Area, don’t miss the nature walk video series from B&E’s Trees on YouTube: . They’re full of interesting information on Wisconsin’s spring ephermals.
Fragile points of color, the first flowers in April rise only slightly from the bed of last year’s decay. Bloodroot, hepatica, and dutchman’s breeches announce the new season throughout much of the woods. The marsh marigolds cluster only around a well-watered natural spring.
As April turns to May, whole stretches of the woods are carpeted with pink-and-white spring beauty. Tree leaves are beginning to bud, but the canopy is still wide open for sunshine to reach the forest floor. Both rue and wood anemones are widespread, and ferns are uncurling from their fiddleheads.
Spring took its time in coming to Wisconsin this year, and when it arrived the rain clouds seemed to hang overhead for weeks at a time. All that water had to make something grow eventually, though, and the prairies were in blossom by the end of May.
The Summer of 2013 began with floods, washouts, and landslides across the Driftless Area, destroying roadways and inundating homes in Wisconsin, Iowa, and Minnesota. These events bring significant losses and make dramatic news, but they are not new. To the contrary, the Driftless Area’s rugged landscape owes its very existence to millions of years of erosion by floodwater, and that erosion is an ongoing process. Widespread human construction, by contrast, is a recent development in this environment. The repeated rains and landslides of the last decade make clear that communities in the Driftless Area must plan their land use for the inevitable occurrence of further flooding and erosion.
The Driftless Area is prone to flash-floods and landslides in part because of its unique topography, which has a higher degree of slope than surrounding regions. The following map (view map at high-resolution) is colored by slope to highlight this distinction, with steeper hillsides shaded more brightly than level land. The Driftless Area stands out immediately as the bright swath across the center of the map:
The steep terrain of the Driftless Area increases the speed at which run-off collects into drainage channels, ordinarily an advantage, as it dries uplands quickly and prevents water from pooling into stagnant ponds and bogs. During heavy rains, however, water collects more rapidly than some narrow channels can accommodate, leading to sudden flash floods that erode banks and scour new channels. In the meantime, the saturated hillsides — especially those with inadequate vegetation — lose strength and give way, leading to landslides. These are the very processes that created the jagged valleys and steep slopes of the Driftless Area, a landscape forged in unison with running water.
