Twelve Mile Circle – An Appreciation of Unusual Places

  • Narrowest Point in Maryland

    Maryland is about 250 miles long and about 100 miles wide at its greatest extremities. However, at one point it narrows to less than two miles where it forms its western panhandle. This is due to one natural geographic feature and one artificial line determined by humans. The Maryland-West Virginia border along this stretch hugs…

  • Tombolo!

    I love this word. Almost as much a thalweg. A Tombolo is a narrow neck of land that forms between the mainland and an island, or between two islands, as sand and sediment deposit between them. Waves hit a landform at a specific angle determined by surrounding currents. Over time this can build up to…

  • Lowest Road in Canada

    Recently I focused on the highest contiguous highway in the United States. Today I’d like to focus on the opposite situation in another place in North America. What is the lowest road in Canada? I love a good trick question. Canada’s lowest elevation is sea level, so the obvious answer would be any road that…

  • Trail Ridge Road

    As covered in the prior post, Trail Ridge Road reaches stratospheric elevations. It climbs to become the highest continuous highway in the United States. There it cuts straight through the splendor of Rocky Mountain National Park. Visitors scaling the summit from Estes Park, Colorado encounter another noteworthy feature along this remarkable road. This happens after…

  • Highest Contiguous Road in USA

    Mountainous roads climb to great heights in the western United States. But which one climbs the highest? As with many topics on Twelve Mile Circle, the answer depends. Does the road have to cross a mountain on the way between two points or can it stop at a dead end at the top? Does the…

  • State of the Circle

    It’s difficult for me to believe, but I just hit the six month point with Twelve Mile Circle. So I thought I would take a moment to look back at the site by reviewing some highlights. Maybe I’ll even reflecting briefly upon the path that lead to this point. I wasn’t sure I’d last even…

  • Washington, DC Highpoint Dedication

    Elevation highpoints captivate me from from time-to-time. I’ve visited a couple of state highpoints before (Mount Washington in New Hampshire and Timms Hill in Wisconsin). I also wrote about my triumphant climb to the summits of both the smallest self-governing county and the smallest independent city in the United States on the same day. It…

  • When Categories Collide!

    Here I explore a mashup of two wonderful topics covered in previous posts. I’ll combine the County Highpointers Association and the epilogue to my Smallest County Series. I decided to see whether I could reach the highpoints of both the smallest self-governing county in the United States and the smallest “county equivalent” location recognized by…

  • Lowest Elevation in England

    When one considers elevations below sea level, England doesn’t normally come to mind. Maybe someone thinks of the Dead Sea or Death Valley or parts of the Netherlands as natural choices. But England? Indeed, England’s lowest elevation actually sits below sea level by almost three metres. This spot exists at Holme Fen (map) in Cambridgeshire.…

  • Georgia Border Dispute

    Several news outlets have highlighted a resolution proposed by Rep. Harry Geisinger of the Georgia General Assembly’s House of Representatives. It would seek to move the Georgia border 1.1 miles further north. News media on both sides of the border took immediate attention. For example, the Atlanta Journal-Constitution covered it with”Border war with Tennessee gets…
