Calling all Geologists and Geographers!

[AdmundfortGeographer]

Hey all,

Just got my Bachelor of Science in Geography. Been working towards it for the better part of a decade. I've drawn a collection of semi-realistic maps of (parts of) the Flanaess of the Greyhawk setting. Do a search of my name on Canonfire! and you'll find some of them.

Now that I finally got my degree if I can only get a job!

In geology there are rarely "new" systems - simply old systems that have changed.

And it is not that the two outlets would merge together but rather that one would cut a deeper channel faster than the other leaving it high and dry.

If something were to block the orginal channel the lake would continue to fill until the water was high enough to flow out elsewhere. If the blockage was removed at just the right time then you could have two outflowing rivers, but again it is hard to conceive of the situation lasting.

Hey all!

I'm the guy who suggested this thread, after I saw four or five geologists/geographers reply to one of the threads mentioned by Maldin.

I'm earning my Masters in sedimentology and sedimentary petrology, working on the Triassic-Jurassic Deerfield basin in Massachusetts.

In fact, the late Triassic Pangea-rifting world is the baseline ecology/climate/tectonic setting for my campaign, mega-monsoon and all. My PCs were disappointed when I revealed that the biggest dinosaur they'd run across was a dilophosaur (damn your lies, Jurassic Park!).

As for the two-river lake problem, I would suggest that it's simply a mass transfer problem. If you have a lake with one inlet and one outlet, but change conditions such that in>>>>out, the initial response would probably lead to multiple outlets. If the increased inflow conditions persisted, the original channel (longest lived, therefore most developed) would eventually incise to the point of accomodating all of the outflow, and the secondary outlets would dry up. It's a similar situation to humid alluvial fans, where a single channel persists until a significant rainfall event, after which multiple streams form across the slope.

Thanks

Hmmm. I was actually going to post in the help wanted forum for a cartographer with a "scientific" background, and then I found this thread.

This seems like a much better place to get the kind of help I am hoping for.

Anybody here want to help me (privately) with a map I'm struggling with?

The continents are more or less "fixed" but I need someone to place mountains, rivers, and towns; discuss human migration patterns/travel times; glaciers; etc.

Send me a PM if you're willing to help on any level.

Here's a question someone might be able to answer here.

Volcanic islands generally run in chains and drop off fairly steeply. I want a set of volcanic islands that has a large number of reefs around them. Am I going to have any problems with this, or is there a particularly apt explaination I ought to be using?

Reefs grow in shallow waters - with fantasy it is easy to fudge the depths a little as long as you stay within the layer light can penentrate. Just show some restraint and look at a real world map.

Also remember volcanos don't have to erupt out of the top, they often erupt from weak spots in the side which means the underwater topography isn't necessarily a smooth cone reaching to the ocean floor.

That can open up the areas your reefs appear in.

Another option with volcanic chains, consider that volcanos can can collapse and sink after a period of violent activity. There is a volcano in the Mediterranean Sea that as appeared and disappeared over the past few centuries. It was last claimed by the British, but then it sank. Now that it has reappeared the Italians are claiming it.

The point is that if you say that the volcanos in the chain were once much more active, them some collapsed in, and are now active again, you could have your rings of reefs around newly forming volcanos.

Not sure why...

Email is good too: ben@badaxegames.com

I was thinking of something like this, but since there are so many geology experts on EN World, I thought I'd ask for ideas.

Thank you very much.
