  • Ohio River, Part 7 (Corydon Loop)

    We used Louisville, Kentucky as our home base for the week and we took several day trips into the countryside. Because the drive to Louisville took a toll on us we decided to relax early in the week. Then our first foray focused on Corydon in nearby Indiana, barely a half-hour away. Something else figured…

  • Appalachian Loop, Part 2 (Vistas)

    Notions of endless horizons came to mind as I prepared for an Appalachian Loop. We would cross mountaintops, dip into hollows and follow valley flatlands along tumbling rivers amid early signs of spring. This journey promised stunning scenery in a little-visited and often under-appreciated rural preserve. People who ventured into Appalachia as tourists usually came…

  • Lowest Landlocked Elevation

    All sorts of interesting facts emerged as I mashed-up Wikipedia’s List of Elevation Extremes by Country with Landlocked Country. I wondered about the lowest elevation of a landlocked nation as I sorted through results in various ways. It turned out that there were several such countries with elevations below sea-level. Anybody could focus on elevation…

  • More Endorheic in Europe

They’ve appeared several times on the pages of Twelve Mile Circle over the years. I’ve even discussed an example in Europe before, Lake Neusiedl on the border between Austria and Hungary.…

  • Hot Springs Everywhere

    Twelve Mile Circle has featured hot springs before. There was Hot Springs, Virginia in Taking a Bath. There was Hot Springs County, Wyoming and its county seat of Thermopolis in The Largest Smallest US County. Geothermal activities existed in many places and I’d taken notice plenty of times. Nonetheless it mildly surprised me when I…

  • Now You See It, Now You Don’t

    I thought about rivers, specifically those with segments that disappeared for awhile. It wasn’t about completely subterranean rivers although those were certainly fascinating in their own right. Rather, it was about surface rivers with underground components. I knew they existed because I had a hazy recollection of reading about one once. How rare were they,…

  • Turlough

    Sometimes odd geography intersects with odd geology. One particularly rare example occurs on the island of Ireland. It’s called a Turlough or Turlach. Described very simply, it’s an ephemeral lake that appears during the wetter months of autumn through springtime and dries-up during the summer. Most of the examples happen west of the River Shannon.…
