A Single Point on the Border
I encountered a number of interesting situations as I pulled together my recent series of borderlocking articles. One of those revelations pertained to Jeff Davis County(1) in the State of Texas. Examine its layout closely. Clearly it borders on Mexico. However that happens only at a single point along the Rio Grande River at its…

Closest Border Monuments — Found!
I wrote recently about the many thousands of tiny segments that form the boundary between Canada and the United States. Fittingly, I called the article Canada-USA Border Segment Extremes. I’d been following up on a query from loyal reader “Greg”. Back then he asked if I knew where he could find the shortest of those…

Canada-USA Border Segment Extremes
Many superlatives describe the border between Canada and the United States. It’s the longest non-militarized border on the planet. It touches three different Oceans (Atlantic, Pacific, Arctic) plus the Great Lakes. It extends 8,891 kilometres (5,525 miles). While impressive, this isn’t about any of that. No, I’m more interested in the extremes in the opposite…

Cross-Province Municipalities
Usually towns that rest upon a border are distinct entities. They may have the appearance of a single contiguous municipality but often that’s deceiving. Two separate local governments actually administer the two separate portions. Kansas City along the Missouri/Kansas border comes to mind: one metropolitan area; same name; different municipal governments. However there are two…

Coordinate Palindromes
I noticed an odd query on the site earlier today. Someone was searching for “Coordinate Palindromes in Nebraska.” I know exactly how they arrived here because the search engine linked them to one of my previous articles featuring Place Name Palindromes. However, I had no familiarity with what could possibly be considered a coordinate palindrome.…

American Meridian
The international community recognizes a prime meridian that runs through the Royal Observatory at Greenwich in southeast London, England. It serves as a reference point for universal time and distance. However, that has not always been the case. Latitude is easy. The equator divides the planet into northern and southern hemispheres quite logically. Longitude is…

A Week in Maine, Part III
I’m quickly approaching the end of my way-to-brief holiday to Maine’s midcoast region. There’s time for one more set of vignettes and then I’ll get back to all the geo-oddities I’ve held in reserve awaiting my return. We spent another day relaxing on the water followed by a day meandering our way further up the…

Just How Wide is Hudson Bay, Really?
Everything about Canada is larger than life. It’s difficult to wrap one’s mind around its incredible breadth and scale. I came across a tantalizing fact that I thought might help conceptualize its vastness. Actually it’s a clever little illusion, some geography-slight-of-hand. In fact I think it’s more enjoyable as a mind-bender than as a trivia…

Mountaineering by Subway
Let’s climb to the summit of a significant highpoint. This video approaches and then transitions to a panoramic view from the summit of the highest point of elevation in the District of Columbia. But that’s getting a little ahead of the story. Let me explain how I found myself here recently. Here is “Point Reno”…

Greatest Time Zone Jump
People seem more interested in time zone anomalies than many other quirks I discuss. I know this because I get lots of random one-time visitors to the Twelve Mile Circle via search engines. Invariably they are searching these kinds of queries. I like them too, but I try not to overwhelm my regular readership with…
