Lower Narrows, SNA #533 (45/674)

Lower Narrows is a beautiful and great example of the geologic history of our state.  It represents a break in the Baraboo Range and was likely carved by a preglacial river.  Today, the Baraboo River flows through the 900-foot wide, 230-foot high gorge.  Further to the west, another SNA, Ableman’s Gorge, represents a similar break in the range and is referred to as the ‘Upper Narrows’.  Rhyolite, a volanic rock, is found here, though the bulk of the gorge is Precambrian Baraboo quartzite.  A portion of the rock gorge is exposed as seen in several of the photos below, but much of the SNA (the Narrows’ western side), is covered in a southern dry-mesic forest.  There are some prairie plants present below the gorge, though this is not a high quality example of that natural community.  This is also one of a few places in Wisconsin to see our native cactus, the eastern prickly pear.  On my visit here, I spent most of my time examining the gorge from below and roaming the prairie.  I plan to return and explore the forest a bit more and seeing the area from on top of the rock as well.
