I once climbed to the top of the not-too-impressive highpoint of the District of Columbia, which in fact is subway accessible. I’m all about easy highpointing. The District highpoint is kind-of equivalent to a state highpoint — some lists include it and others do not — so that was a convenient loophole to add another location to my list. I thought about that recently and wondered whether it might be possible to replicate my feat in another nation with a similar capital district.
That required a mashup of two separate lists. There weren’t very many situations like DC although a few were included in Wikipedia’s List of Federal Capitals. I cross-referenced that to the peak lists available on Peakbagger.com. It was sort-of hit or miss since most nations did not have a separate list of state, provincial and/or territorial highpoints. The lists depended upon the good graces of individual contributors to develop them. For example Abuja, Nigeria was a Federal district although nobody posted a list of individual Nigerian states so I couldn’t feature it. I wouldn’t be able to do that for Russia either unless loyal 12MC reader "January First-of-May" just happened to have the highpoint coordinates available for the Federal City of Moscow. I don’t have the data to determine these places on my own.
I found online information about several places though and I’ll list them from lowest to highest elevation.
El Palacio de Aguas Corrientes, Buenos Aires by pandrcutts, on Flickr

The summit of the Ciudad Autónoma de Buenos Aires might be a fair comparison to Washington’s highpoint at a diminutive 38 meters (125 feet) in an urban area. Buenos Aires had a much more impressive water tower, though. The summit was crowned by the impressive Palacio de Aguas Corrientes — the Palace of Flowing Waters — a garish structure that contained a pumping station, water company offices, and even a museum dedicated to water and sanitation. As described by Welcome Argentina,
Down Córdoba Avenue, those who catch a glimpse of this building realize at once that it belongs to another time. Extravagant and ridiculous for some, fascinating for others, the Palacio de Aguas Corrientes… has been a symbol of the pomp of the generation of 1880 and at the same time a key piece for the health of a developing city.
Peakbagger even included an Ascent Trip Report, albeit a bit tongue-in-cheek.
Pico do Roncador
The Distrito Federal in Brazil included Brasília, and of course a highpoint summit which in this instance fell within a rural area of the northwest corner. Various online sources called it Pico do Roncador. Translation software told me that Roncador meant "Snorer." A little digging uncovered a species of fish called Umbrina Roncador or Yellowfin Croaker, and croakers do make a grunting noise that I guess might sound something like snoring (listen).
Was Pico do Roncador named for the fish or was it given the name because it was really boring to the point where it might put someone to sleep? Because I’m thinking the latter. The highpoint fell on a plateau at 1,341 meters (4,400 feet), hardly distinguishable from the surrounding terrain except for the presence of a communications tower visible in the distance on Google Street View.
I felt a little better when I noticed the summit of Bimberi Peak, the highpoint of the Australian Capital Territory. At least it resembled a mountain, and actually a pretty notable one for the area at 1,913 meters (6,276 feet). It’s part of the Brindabella Ranges and straddled the border between ACT and New South Wales in Namadgi National Park. The park’s website claims that the park covered "46 per cent of the Australian Capital Territory" which was an interesting point. Is there any other Federal district covered by national parkland to a greater degree?
Bimberi isn’t supposed to be a particularly technical climb although the peak does extend high enough to make vegetation sparse and it can be covered by snow in the winter.

México won the 12MC award for most extreme federal capital summit, with Cerro Ajusco in the Distrito Federal rising to 3,937 meters (12,917 feet). Like many other mountains nearby, Ajusco had a volcanic origin and was formed as part of a lava dome. One might think the altitude would be daunting however Ajusco may be the most commonly climbed summit in the nation. Why? Because something like 20 million people live within the greater Mexico City metropolitan area, and the heart of the city is only like 40 kilometres away from Parque Nacional Cumbres del Ajusco. Crazy!
Summit Post provided advice to prospective climbers.
… droves of Mexicans flock to its slopes on holidays and on weekends to escape the press of the most populated city on earth… I would suggest the best time to climb Ajusco would be early on a weekday morning so one could enjoy the peak with a degree of tranquility… it should take no more than 2-4 hours (depending on one’s level of fitness) roundtrip to complete.
That’s a little more complicated than the Washington, DC highpoint.
I’m not sure the title adequately conveyed what I’m trying to describe, although I can’t think of a better concise title to replace it either. Conceptually, I wanted to know the northernmost and southernmost places in the world and in the United States where one could cross an international border by automobile via a road connected to the larger grid. There are plenty of places farther north where a crossing could be accomplished on foot, perhaps after a long ship voyage or an airline flight, but not by a motorized vehicle on an established road. Those road crossings would be cardinal direction border extremes for the average tourist as opposed to the adventurous explorer. You know, ones that I might actually experience someday.
These were the best examples I could find. I’d love see improvements.

The absolutely farthest northern road that crossed an international border that I found occurred between Polmak, Norway and Nuorgam, Finland at an astounding 70 degrees north of the equator. By contrast the Arctic Circle is at about 66.56 degrees north. Barrow, Alaska — about as far north as one can get in the United States — is only slightly farther north (71 degrees) and it’s not connected to anything by road, much less internationally. This is crazy far north.
Both nations are part of the Schengen Area so one could cross the border freely. It looked like a former border station had been converted into shops in the Street View image.
NORTHERNMOST UNITED STATES (AND CANADA)

The United States and Canada share the same northernmost international border crossing at Poker Creek, Alaska / Little Gold Creek, Yukon (map) along the Top of the World Highway. It’s located at about 64 degrees north.
This also demonstrated how few roads crossed this rugged, isolated terrain because the border extended another 380 miles (612 kilometres) due north without a single other road crossing it. This border station closes in the winter so I’m willing to concede that purists may wish to look farther south to the Alaska-Canadian Highway for a more complete example, one that remains open 24X7 all year long (map).
What about the Lower 48 states? I think the northernmost crossing would be the place where the border jogs around to form the Northwest Angle (map). Weekend Roady visited this one in person and I won’t try to improve upon his first-hand description.

The record wasn’t clear-cut at the southern end, nor was it quite as extreme. I think it may be a spot on Isla Grande de Tierra del Fuego around 54 degrees south, although it’s not even as far south as Ushuaia (featured on 12MC previously), the southernmost town of significance in Argentina. There may also be an error on the Google Map too. Google seems to have issues with borderlines, a condition I’ve observed before. Notice the vertical fence line about 100 metres west of Google’s line. Could that be the true boundary?

I thought perhaps there might be a car ferry between Ushuaia, Argentina and Puerto Williams, Chile. It seemed natural and I’d be willing to bend the "road" rule to accommodate a ferry. It wouldn’t violate the spirit, right? Nonetheless, Wikipedia said of Puerto Williams, "There is no regular link with Argentina and connection to Ushuaia is restricted." Puerto Williams exists primarily for the Chilean navy to assert national sovereignty at the farthest tip of South America. It was once a rather sensitive military area although tourism has begun to creep in.
Another source said it was possible to travel between the two places albeit not very conveniently, "Ushuaia Boating in Ushuaia, Argentina, has regular zodiac service to Isla Navarino October-March or April. The trajectory is boat from Ushuaia to Puerto Navarino (40 minutes, immigration), then minibus to Puerto Williams." However that wouldn’t qualify as an automobile crossing by any stretch of the imagination so I’m not going to count it.
SOUTHERNMOST SOUTHMOST USA
Eyeball estimates led me to believe that the southernmost border crossing in the United States would be found at Brownsville, Texas where it provided access to Matamoros, Tamaulipas, México. That was located at about 25.9 degrees north. A whole bunch of the world can be found farther south than that.

That’s not what I enjoyed the most, though. I was amused by Southmost Boulevard. That’s southmost not southernmost. A shorter word with the same meaning. It sounded a little odd. Maybe I could get used to it?
Does México have a quadripoint? That’s not intended as a trick question. Ideally this should have an easily verifiable solution. Either four Mexican states touch at a common spot — a quadripoint — or they do not. The answer however is considerably more elusive. I remain at a loss as I attempt to uncover whether someone should reasonably conclude one way or the other.
There are a couple of candidates, and the Mexican states of San Luis Potosí and Zacatecas are common denominators.

Notice the relative proximity of the states of Jalisco, Guanajuato, San Luis Potosí, and Zacatecas. A small notch of Zacatecas protrudes just far enough south to prevent Jalisco and San Luis Potosí from sharing a common border according to Google Maps, with all of the usual caveats about the accuracy of Google Maps. The situation seemingly separates the two states by about 1.88 kilometres (1.17 miles) according to my quick calculation.
This is an agricultural area farmed and ranched fairly intensively judging by satellite mode and confirmed by proximal Street View availability (sample image). There’s even a ranchero within the Zacatecas notch, which would be an interesting geo-oddity homestead for the lucky resident: a click east to San Luis Potosí; a click south to Guanajuato; a click west to Jalisco. It’s easily accessible from the nearest town, Ojuelos de Jalisco, less than 12km down a road called Deportiva (which translates to "sports" and runs by the town’s athletic fields as it departs town). A driver would also cross the border between Jalisco and Zacatecas a couple of times for good measure too (map).
This happy confluence of multiple borders didn’t seem to be controversial. It did in fact appear to represent two tripoints falling in very close proximity to each other. A cube of Zacatecas less than 2km on a side blocked a rare opportunity for a quadripoint.
The other potential Mexican quadripoint takes place in the vicinity of Coahuila, Nuevo León, San Luis Potosi and Zacatecas either where they all join together or where they all nearly do so, depending on the evidence one chooses to accept.

Google Maps sides clearly with the camp that believes in two tripoints in close proximity to each other rather than a single quadripoint, once again considering that Google isn’t the arbiter of all things geographic. However, notice the distance between to two tripoints: 12.17 km (7.56 mi). It would hardly seem to be a question with such a sizable gap. Yet, other maps are much less clear including some published by the Mexican government. The Yahoo! Group "boundarypointpoint" which specializes in just these types of situation appeared to have reached a consensus that a quadripoint did not exist, after lengthy discussions and earlier research.
However, a monument exists at what many would call the northern of the two tripoints, the "Mojonera de los Cuatro Estados" (Marker of the Four States). There are various photographs of the marker posted on the Intertubes although none that I could find with Creative Commons licensing so I couldn’t embed them here. Feel free to open a photo from Panoramio or from Flickr in another tab and observe the results. The marker would be readily accessible albeit after enduring a jarring 8.1 km (5.0 mi) ride down a rough road. I think the guy in the Flickr image with the mountain bike had the right idea.
Wikipedia bought into the idea of a Mexican quadripoint, for what that’s worth. It was presented as fact without citing any evidence, and was immediately flagged as such. Wikipedia attempted to weasel-word around the issue by stating that this is the place where the four states "effectively" meet. Right. I’m not sure de facto or close-enough provides a decent standard for a concept that implies precision. Even the contributors on boundarypointpoint seemed conflicted after the revelation of the Mojonera de los Cuatro Estados.
Examining the Mexican Geological Service website, Servicio Geológico Mexicano, provided nothing definitive and Internet searches using the Spanish-language term "Cuadripunto" yielded no better results either.
Was it a situation created by imprecise surveying techniques like the Delaware Wedge? Is it so rural and effects so few people that the governments involved simply don’t consider it enough of a priority to figure it out? Or has it been overtaken by events with a named boundary stone, the Mojonera de los Cuatro Estados, converting a close-enough approximation to an exact declaration?
In my mind, the elusive Quadripoint of México remains a mystery.
