  • Portage in Canada

    The United States Geological Survey is a Federal government agency. It has been impacted by the government budget impasse that exists as I write this article in October 2013. Guess what? It also means that the Geographical Names Information System was turned off. Only websites “necessary to protect lives and property” are running at the…

  • Odds and Ends 9

    I’ve collected another raft of small discoveries not nearly meaty enough to stretch into an entire article on their own. 12MC readers have also been kind enough to make me aware of some unusual situations. That must mean it’s time once again for an installment of Odds and Ends, our ongoing collection of bite-sized morsels.…

  • I Call Bull Shark

    What a glorious day for boating on the tidal Potomac River around Mason Neck, south of Fort Belvior. A friend asked it we’d like to join him and his family for a day on the water and of course I couldn’t turn down such a generous offer. We spent most of the afternoon on the…

  • 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…

  • Island Became Mainland

    Twelve Mile Circle is always up for a good challenge. So, loyal reader Greg laid-down the gauntlet yesterday in the friendliest way possible. He commented on Largest Artificial Islands: “A more common phenomenon, surely, must be islands joined to a mainland by landfill. So what about the opposite of this post, the largest former islands?“…
