  • Plank Roads

    I used to drive between Washington, DC and Chapel Hill, North Carolina, nearly every weekend for about eighteen months a number of years ago. I became very familiar with the route and every landmark placed upon it as one might imagine. One of those included an exit for Boydton Plank Road along Interstate 85 near…

  • Loess

    What do Council Bluffs, Iowa, the Battle of Vicksburg and the Yellow River all have in common? Loess. Loess comes from the German löß, and has a common root with the English word, loose. This geological term describes a light silty dust blown by the wind that accumulates into thick layers and hills. These deposits,…

  • Tombolo(s) of Connecticut

    I have an odd affinity for tombolos. I don’t know why. It’s completely irrational. Even one of the earliest Twelve Mile Circle articles focused on the phenomenon. I’ll stick with a definition I drafted back then and quote myself. “A Tombolo is a narrow neck of land that forms between the mainland and an island,…

  • Oxbows in Africa

    I’m sensitive to the frequency of 12MC article pushpins that increase exponentially as one gets closer to my approximate home. I write about what I know best, and geographic distance permeates that equation. That leaves many areas of the earth underserved and creates a vicious circle. Residents of those places don’t hit the Twelve Mile…

  • Kentucky Adventure, Part 6 (And the Rest)

    All good things come to an end and before long our Kentucky adventure approached its natural conclusion. It was time to return home. I still had some parting opportunities as I left the state and then again as we steered through West Virginia towards the Mid Atlantic. East Wasn’t East Long ago in the early…

  • Kentucky Adventure, Part 4 (Power of Water)

    I noticed a common theme intertwined with water as we explored the southern tier of Kentucky, from Lake Cumberland to Mammoth Cave: water as an historical and modern source of power; water as a recreational activity; water as an obstacle and water as a force of nature. The Cumberland River and the Green River, both…

  • Kentucky Adventure, Part 3 (Appalachian Heritage)

    Geography and history dominate southeastern Kentucky. Those were primary reasons for my selection of this corner of Kentucky when I decided to feature it as my U.S. State of Focus(¹) during the Summer of 2013. Twelve Mile Circle concentrates foremost on geography. However, one never avoids history here completely either. The two went hand-in-hand during…

  • Largest Artificial Lakes

    I had some fun with artificially created geographic features lately. First I featured the largest artificial islands and then islands joined artificially to the mainland. Now, I thought, I’d flip the concept to the opposite extreme. Instead of land on water, how about water on land? What might be the largest area of terrain intentionally…

  • Largest Artificial Islands

    My favorite inspiration, the random one-time visitor, struck again. Honestly I don’t know why any of them land on Twelve Mile Circle. This time the person wondered about the world’s largest artificial island. Repeat after me: search for “Wikipedia Largest Artificial Island.” Why come to 12MC when Wikipedia has a wonderful answer already prepared? I…

  • Africa’s Lowpoint

    I was poking around the CIA World Factbook (doesn’t everyone?) and came across an interesting page that listed “miscellaneous geographic information of significance not included elsewhere.” That’s wonderful, I thought, a page of international odds-and-ends that didn’t fit within the book’s prescribed format. Yes, I live for moments like that. It listed little tidbits on…
