I would think with a cross section you would be able to see the offset strata layers in the dip/slip fault but with just a top view there wouldn't be a difference.

So I've done science Olympiad as a middle schooler and now that I'm in highschool my friends have started a SCIOLY team there so we are all new to this and as treasure of the team my job is to get the supplies and I was looking at the geologic compasses and saw that they were a bit pricey and we're pretty tight on money so I was wondering if you guys could send me links to geologic compasses that you guys use for these events that are good but still somewhat cheap. Also do you guys actually use the geologic compass or would it be ok to just use a regular one?

We borrowed one from somebody, a friend of the team works for the USGS so that was convenient. Honestly I wouldn't worry too much about the geologic compass as I've never actually used it in competition.

Geologic compasses are new to Geologic Mapping this year, and they are not very different from normal compasses; buying an expensive one would not be worth it. I'd say get a basic compass that is accurate, or use one that you have.

The second one.

Oh OK. Then I'd probably also watch out for quality when buying those because some of those types of compasses out there on the market are probably super cheap but dysfunctional (I've seen them, they're horrible). By no means do I mean that you should spend a lot of money on a compass, but don't buy one that malfunctions and wastes your money. But having done this event for two years without one, I'm not exactly sure what you'd need to use it for. I mean, to point out which way north is makes sense, but maps usually indicate that on a compass rose drawn on the map...I think. :?

Well, sometimes you can get sections of maps (happened to me when I competed). I did mention some other reasons on the first page relating to structural orientation as well. I think there might be some other explanations/links on the Geomaps topic last year or somewhere, but I can't remember.

Hello! I'm new to this event this year, and I was wondering what the rules mean by "geological principles"? Thanks!
