  • 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…

  • No Names and Nameless

    The article on Public Streets seemed generate more than the usual amount of interest and lots of great comments, as well as a hint of familiarity. Input from loyal reader David Overton sent me down an interesting tangent. He mentioned No Name Street, which he believed might be “another contender for ‘laziest street name’”. He…
