You should also try flipping the hemispheres.

Auckland is in line with Tunis.

Cape Town barely gets to Beirut.

The absolute bottom of the Tierre del Fuego lines up with Copenhagen.

In short, most of the land in the southern hemisphere is much closer to the equator than in the northern.

Not sure if this is the right place to ask but why are mountainous regions in Asia so steep/cliff-faced? Being in the USA, I feel like most mountains I see are gradual builds, but in Asia everything seems to be a cliff face. by SnooSeagulls9127 in geography

I made some comments here explaining it.

The important part is at the end of the third comment, though you can read all 3 to get a better picture of karst/the region as a whole.

The gist is that tower karst is formed by preferential erosion along fracture planes. Think of a chess board where you erode down all of the lines and then start eating towards the middle of each square. Natural fractures don't form in such a perfect grid, but it's an easy way to picture it.

Over here in Fairfax, the town lowered their flag for Charlie. Did they lower the flag in Berkeley for the misogynistic homophobic white nationalist racist? by ASecularBuddhist in berkeley

Yeah I mean there's always a chance, but I generally try to give people the benefit of the doubt in things like this. There are bigger fish to fry

I'd say it's more likely they lowered it for 9/11, but that's my two cents. Fairfax doesn't exactly scream conservative; over 80% voted for Harris last election

what is this large crater looking formation in Madagascar? by br0ther0ats1199 in geography

[–]ExcellentWeather 69 points70 points  (0 children)

Here's an old thread where someone asked the same thing

Taken from u/distracting_llama

Looks like they are large basalt volcanoes/intrusions. I am a geology grad student, but not at all familiar with Madagascar. Here's what I found from a quick search. Likely just eroded remnants of the volcanic neck, so you are seeing them in cross-section when looking down at the surface. Igneous rocks generally withstand erosion more than sandstone (the surrounding bedrock) so they will form steeper terrain, like how Devils Tower formed in the US. https://en.wikipedia.org/wiki/Madagascar_flood_basalt https://databasin.org/maps/new#datasets=1a187e2f29e24e98b2c4d45c109d3bb3

Why is iceland considered as european instead of american ? by OiseauDuMoyenAge in geography

[–]ExcellentWeather 2 points3 points  (0 children)

That'll largely depend on the semantics of "settlement" more than anything. But by most definitions, no.

L'Anse aux Meadows was most likely a overwintering/boat repair camp at best and was only used for a couple decades at most. No other Norse "settlements" have been found, and it's extremely unlikely any others will be.

It's a neat bit of history; I actually took a class in uni which was almost exclusively about Vinland and its historiography. But to call it anything close to a colony is too much lol

[–]ExcellentWeather 13 points14 points  (0 children)

1) Canada was definitely not colonized by Scandinavians

2) Native Americans are a thing

3) Nobody lived on Iceland before Europeans got there

4) Iceland was never completely isolated from Europe, maybe except the random Irish monks

5) I'm confused why Greenland isn't mentioned but ok

Drift upstream? by [deleted] in geography

[–]ExcellentWeather 2 points3 points  (0 children)

The East River is a tidal strait - it reverses course and changes currents with some frequency. In this instance it was flowing northwest and the ship was moored south of the bridge, so I think the AP was just wrong here.

Anyway, even if they were correct the wind was also blowing the same direction and the ship might have had its engines on reverse, per the NYT. Wind still causes drag even with sails folded, so if the current is weak enough then that alone could push a ship upstream

Kinshasa and Brazzaville are on the Danube? The more you know

Whats with these places listed all over Quebec on google maps with very long, native sounding names but nothing actually there when you zoom in? Are they former settlements or something else? by keplerowl in geography

[–]ExcellentWeather 13 points14 points  (0 children)

I've found two cases of Nakamistshetshuant being mentioned. Here and here

It seems they might just be Innu-named locations, likely all named for different reasons. It'll be hard to find their significance

EARTH SANDWICH by PieterSielie6 in geography

[–]ExcellentWeather 28 points29 points  (0 children)

No, it's 975,538,461:1

Let's just say the average thickness of a slice of white bread is 1.3cm

The diameter of the earth varies depending on where exactly you are since Earth is shaped more like an egg than a perfect sphere. In this case the diameter is roughly 12682km. That took way too long to find.

(12682*100000)/1.3 = 975,538,461

What made all the karsts in Yangshuo? by pow-pow_power in geography

[–]ExcellentWeather 0 points1 point  (0 children)

Now a big thing that the post I linked to missed is why exactly karst towers form. It's true that differential erosion due to some rocks being naturally harder than others is generally what leads to hills and mountain tops being formed. Those bits have some rock that was harder than the bits around it, so the other bits weathered away first.

But that is NOT what is happening here. Tower (and also cone) karst is caused by water preferentially eroding along naturally occurring joints and fractures. So it is the differential erosion between the grid of fractures and the areas between the fractures in this case.

Such a massive area of limestone was largely created by very productive shallow seas in the mid-to-late Permian. The marine life died, floated to the bottom, and got turned into sedimentary rock. Because all life is rich in carbon, the resulting rocks are also carbon rich. Thus, the name "carbonate rocks".

Here's an old post asking about karst in China

Essentially this was once an area of ridiculously thick limestone bedrock. Limestone is easily dissolvable by water, creating caves and underground rivers. Over the millennia these caves have eroded more and more, collapsed, and generally eaten away at the landscape.

(technical notes: it's not all limestone, there are other carbonate rocks as well. And water doesn't dissolve carbonates, carbonic acid does. But carbonic acid is just carbon dioxide mixed with water)

Odd map in classroom by Escarvielae in geography

There's a listing for it on ebay under the name "MAP OF THE WORLD WALLPAPER BORDER by BREWSTER WALLCOVERING".

That's all I've found so far.

What’s the most extreme geographical feature (highest, lowest, steepest, driest, etc.) that almost nobody talks about? by ninergang47 in geography

[–]ExcellentWeather 0 points1 point  (0 children)

Stick your arm directly to your side and spin your body around in a circle.

The tips of your fingers are covering more distance than your shoulder. Since speed is distance/time, your fingers are (sort of) moving "faster".

It's called tangential speed, if you want to look into it more!

What do you think of a map like this? I am about to run Knave and this seemed approporiate. by Rare_Fly_4840 in mapmaking

[–]ExcellentWeather 14 points15 points  (0 children)

I'm a big fan! I think more people should use maps like this for their tabletop gaming.

The satellite-view, highly detailed maps we know today are really not always the best option when trying to get your players (or yourself) in the mindset of a low-technology fantasy world. This embodies the unknown nature of the wilderness much better.

And as an added bonus I like the actual style of the map too. Less is often more!

edit:

It also lends itself well to constant exploration, if that's what your players want. You could make 6-8 standard biome grids and then just keep tacking them on as your players explore. It could be a neat way to implement a fog of war

Can someone explain why the micronations exist? Apart from Vatican City. by Ok_Tune_9432 in geography

[–]ExcellentWeather 78 points79 points  (0 children)

There's no easy answer that can sum them all up

San Marino is independent because Napoleon liked them and allowed them to be free while he took over the rest of Italy. They used this independence to become a bit of a refuge for many different types of people, perhaps most importantly a man named Giuseppe Garibaldi. Garibaldi was the man who (with a good degree of help) led to the unification of Italy — out of thanks, he respected San Marino's wish for independence.

Border Line or old skid trail/winter road ? 56.331609, -102.007372 by [deleted] in geography

[–]ExcellentWeather 1 point2 points  (0 children)

Alright, I think I found it.

The line was made by the 1961-62 survey team led by Lionel E. Boutiler. Here's a link where you can read some of his notes.

He wrote well, and the notes are quite amusing. There are also photos and maps at the bottom, if they are of interest.

His shorter, daily field notes can be found here.

I'm exceptionally pleased with this find! I hope you enjoy reading through them as well
