Depends. Topographic maps were a big part of the test last Saturday at the Atlanta Westminster Competition, but it really depends on the event supervisor.
Do you happen to have any tests that you could scan onto the test exchange, regardless of the event?

It is really hit-or-miss. The rules say: "topics include, but are not limited to:", which mean that the test could be all about one topic, evenly distributed about every topic, or it could include absolutely none of the topics listed on the rules. Rfscoach got it as it is entirely up to the event supervisor and what they want to write a test about.

The topics listed on the rules are very important in studying, as that is the first place event supervisors do, or at least should, look at when writing the test, but in order to really be good at the event, you should go beyond the topics in the rules.

Anyway, if you can basically learn how to understand the topographic maps, such as what the contour lines are and how to use them, and the symbols are a good thing to put on your resource sheet.

I'm currently studying for this event but I don't know much about it and I'm curious to see examples of questions. If anyone can post links/upload/send practice tests, that would be awesome :)

So I'm kinda confused about the difference between an artesian and a non-artesian well. From what I can tell from the diagram on one of the links that the wiki provides, is it just one that penetrates the saturated zone instead of penetrating the unsaturated zone and then the saturated zone? In other words does it not penetrate the water table?

well an arttesian well is one that does not require a pump where as a normal well requires a pump or a bucket

This picture really tells it all:
http://geology.com/articles/bottled-wat ... n-well.gif
The aquifer is between the two impermeable layers, but the zone or recharge (the place where water is added to the aquifer) is up hill and the aquifer slopes down enough to put the top of the well below the water level. This means that the water can rise up a well simply by water pressure. You will notice in the image that the Artesian well on the left is still a bit higher than the zone of recharge. So you would still have to pump the water up a little bit.

EDIT: Sorry, the picture showed up in the preview...

When it comes to the future, there are three kinds of people: those who let it happen, those who make it happen, and those who wonder what happened.

Am I the only one who can't see the "image"? Can you put just the link to the picture because the description is kinda hard to understand without it. Thanks for trying either way

Let's see if this will work.

Could someone help me with karst features? I have basic information about what karts is and how it forms, and I have a whole list of features, but I can't find one source that just goes through each feature and explains how it's formed and what it looks like, etc. I know there are plenty for caves and sink holes, but I keep skipping over that looking for something that explains everything. Has anyone found a resource like that?

Edit - I think I actually have enough now, never mind :)
