What happens in meetings: a draft map of part of the Unspoken world

Notes: The text along the left says "can there be a river here?"

I have doubts about the lower river, by Orschëst, because an unposted story (waiting for y'all to help me name the city... here) has a desert to the west of that dot under Orschëst... also river placements weird. But Orschëst needs to have a reason to be where it is...

Thoughts? Oh mappy people?

Orschëst's location may be due to resources other than water - could there be a mine there?

With the desert, what latitude is it at? Is there a feature that blocks the prevailing moisture bearing winds? Is the desert even natural?

The desert is def. not natural, but it can't be on the river. I think.

Mine's a good idea.

A mine or similar natural resource is a fine idea.

Why can't you have a river running through a desert? See the Nile, the Los Angeles River, ...

That said, I don't grok geography and weather patterns well enough to say you need this-this-and-this to make a desert. Prevailing winds and mountains and bodies of water and a bunch of other things all matter. You get effects like air being pushed up and over mountains getting colder and dropping all of its water before hitting the desert ... but that's only one of many things that can happen.

Can you? I'm not very familiar with deserts.


Very simple map of Africa with Sahara Desert and Nile
Much of Egypt is desert. Water for irrigation is all pulled from the Nile, which also used to be the source of most of the fertile soil during the spring floods. (That changed with dams and hydro power and stuff -- more reliable water, less rich silt.)

A desert is IIRC about precipitation in the area. Deserts can border oceans and have rivers running through them. Deserts can have flash floods. Desserts don't have to be hot (most of them are cold at night -- dry air doesn't hold heat well -- and high deserts can be cold all the time) or sandy.

Joshua Tree is what I thought of as desert as a kid -- rocky, red and gold, grey-green plants adapted for low or intermittent water. That sort of desert can have spectacular blooms on very short notice when there's a storm or flood.

And even the Sahara (which I think of as the iconic endless sand dune desert) has springs and oases -- their effects are just very local.

<meanders off distracted by wikipedia>

Okay! (Thank you!!)

So the desert can go up/over there *moves it mentally* I like that.

Shiny distraction: Endorheic basins.
(ETA: I was looking up the Rio Grande, which I think also runs through dry and desert areas ...)

I f the e-mail I have for you is still correct, I e-mailed you a thing.

Indeed you did!

Another shiny distraction: the Dry Valleys of Antarctica, which are very cold deserts.

(Boggle?) Which ....

OH! "A mine's a good idea", not "My idea's a good one." Boingggg.
