Lots of Monarchs on the Lowland Plain at Broad Run Park today. As I was running in they were flying out of the bushes. Several people swimming in the creek. The low water level created some nice little rapids. I ran up through the woodland garden and turned around at the overlook. Caught a Marbled Orbweaver on camera. I could have loped around to Karst, but I went back the way I came to stay by the creek. Saw a little water snake and a ground hog. Lost some good video footage because the camera was in time lapse mode.

Past and Present

Watching the water swirl through those shallow limestone chutes got me thinking about how long Floyds Fork has been carving through this valley—long before John Floyd first surveyed this land back in the 1770s. It’s funny how a creek can make you ponder big science news; just this past week, AI labs and mathematicians made global headlines claiming a breakthrough solution to the century-old Navier–Stokes equations. Standing on the bank, watching the tiny eddies spin off the rocks, it was wild to realize that the complex fluid dynamics thousands of AI agents spent millions of tokens trying to model were playing out effortlessly right in front of me in a Kentucky stream.

Water has a way of connecting everything, whether it's a quiet creek in Louisville or the narrow shipping channels of the Bab al-Mandab Strait driving tense headlines across the globe this week. Geopolitical conflicts and corporate AI races come and go, but out on the Lowland Plain Trail, nature keeps its own steady, unbothered rhythm. The late-summer sun lit up the bright yellow wild sunflowers bordering the path as I jogged the last mile back toward the lot. No matter how fast technology moves or how turbulent world events get, a peaceful run along a clear stream is still the best reminder that the natural world always finds a way to keep flowing smoothly.

Marbled Orbweaver (Araneus marmoreus) - Often called the "pumpkin spider," is a striking, harmless arachnid common to woodlands, parks, and meadows throughout North America. Best known for its bright, marbled abdomen—which frequently matures into vivid shades of orange and yellow in late summer and fall—this spider is a master weaver of classic spiral orb webs. Rather than sitting in the center of its web during the day, a female cleverly constructs a hidden retreat by silk-tenting a curled leaf nearby, keeping a single leg on a signal thread to feel prey vibrations. Non-aggressive toward humans, the Marbled Orbweaver is an invaluable pest controller that keeps populations of mosquitoes, flies, and moths in check.
