Northernmost Romans in Britain
Romans occupied and controlled a large southern swath of the island of Great Britain as they expanded their empire. How far north, I wondered, did they extend their empire there before it began to contract? What was their high-water mark? Hadrian’s Wall The Romans arrived on Britain in the year 43 and would remain as…

Longest Natural Straight Line
I once featured a stretch of completely straight railroad track across the Nullarbor Plain. It ran an amazing 478 kilometres (297 miles), in Australia’s Longest Straight Line. I’ve also focused considerable attention on the Canada-United States border. That one hugs the 49th degree of latitude north for something like 2,000 km (1,250 mi) — although…

State Centers of Population
The concept of population centers fascinates me. In the United States the U.S. Census bureau defines the Mean Center of Population. “The point at which an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if weights of identical value were placed on it so that each weight represented the location…

The Pinetree Line
I’m not sure how I stumbled upon the Pinetree Line. It seemed to be a particularly descriptive term though. So I guess I tucked it away on my list of “things to ponder later.” It was a Cold War manifestation, an effort by Canada and the United States to provide an early warning system should…

Better Sister Cities
Sister Cities International’s mission promotes “peace through mutual respect, understanding, & cooperation — one individual, one community at a time.” I find that laudable although I wonder how they establish these relationships. Does it involve some sort of affinity perspective or does someone simply say, “hey, wanna be our sister city?” My hometown — Arlington,…

Utah Adventure, Part 1
The hunt for geo-oddities in northern Utah is well underway. The family will want to visit more recognizable sights so I’ll have to mix in a few “normal” tourist activities along the way. I have to maintain a careful balance. Thus I need just enough to keep them entertained while giving me an opportunity to…

Back to the Lines
My fascination with lines returns as a recurring theme once again on Twelve Mile Circle, like previous articles such as Wisconsin vs. Florida, Reno vs. Los Angeles, and Glasgow vs. Madrid. I found myself thinking about lines of latitude and longitude this morning when I noticed a random search engine query that pondered whether Portland,…

Odds and Ends 2
Previously I composed of a collection of random thoughts, none of which merited an article on its own. It seemed to make sense to call it Odds and Ends. So I plan to do the same thing again today. Logically I should call this one Odds and Ends 2, like any good Hollywood blockbuster. Salt…

Bull’s Eye
It’s been awhile since I’ve given much thought to the Degree Confluence Project. I featured them in the earlier days of the Twelve Mile Circle, nearly three years ago as I recall. The project has its roots in a time before the complete ubiquity of the Internet, when the web was still capturing public attention…

Definitely Halfway
I think it was back in January when I focused on the little town of Halfway, Oregon. I was pretty impressed when I thought they’d named it that way because of the nearby 45th parallel of latitude north — i.e., halfway between the equator and the North Pole. That turned out to be a false…
