Southernmost Northern Permafrost
Permafrost is defined as soil that maintains a temperature at or below freezing for two complete summers and an intervening winter. Actual “frost” doesn’t need to be present. Also the extent of permafrost in the Northern Hemisphere varies dramatically. It depends on many factors including topography, seasonal weather patterns, and permanent climate change. There are…

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”…

Do you notice anything remarkable about this little patch? It seems like this must be the middle of nowhere, just a sea of red soil and desert scrub removed from any hospitable place. However, according to some calculations, this is the centre of Australia. Am I the last one on the planet to know that…

Two invisible lines cross near the small town of Poniatowski; one representing 45 degrees north latitude and one representing 90 degrees west longitude.

Mac and Cheese
I’ve gone Mac! Actually it happened a few weeks ago but it took me a little while to feel proficient. Even so, I don’t want to turn this into a Mac versus PC discussion. People make choices based on personal preferences and that’s fine. Instead, I’ll focus on a couple of different mapping features I’ve…

Canadian Border Anomalies
I’ve discussed border anomalies between the United States and Canada before. Previously I focused on little areas of the U.S. separated from the rest of the country such as Point Roberts, the Northwest Angle and Alburg, Vermont. Here I give equal time to the Canadians. I’ll outline a couple of instances where citizens of that…

Australia’s Shortest Internal Border
What is the shortest border in Australia between any state or territory? Take a look at the map and see if you can figure it out. You won’t, but try anyway. Australian Capital Territory and New South Wales? If I were forced to guess quickly I’d probably say that a likely choice would be the…

Colorado is NOT a Rectangle
Take a look at Colorado. Go ahead, stare at it for awhile. How would you describe its shape? Here’s the question: (a) It’s a rectangle. (b) It’s not a Rectangle I’ve already given you the answer and it’s not a trick question so there’s no way you can earn anything less than an A+ on…
