In section 3.n. the rules mention that we must know methods of studying glaciers: Altimetry, radar . . . but as far as I can tell radar is a type of altimetry. Does altimetry refer specifically to laser altimetry, while radar refers to radar altimetry? Did I misunderstand something?

An altimeter measures altitude. Radar can be used for altimetry while it can also be used to study the interior of glaciers, measure thickness of ice, etc.

Agreed^ Here's a great source to see different types of altimetry and different radar instruments in action: https://visibleearth.nasa.gov/

Can anyone explain the differences between a finger lake and a ribbon lake? I have seen both terms refer to what appears to be the same thing, so I feel like there is something I am missing, but I haven't been able to find any definitive information.

Okay, thanks. Like, do you need to know what rogen moraines and H,N, and R channels?

I would learn about them


Is this advice for Div C only or Div B as well?

On the Scioly Test Exchange, is there anyway to bulk download them? Kinda a pain to have to click dozens of links like that. Thx

You should learn as much as you can for either division as long as it's within the scope of the rules :)

Well, that is the question. Neither 'rogen moraines' and 'h, n, and r channels' are mentioned in the Div B Rules.
They are not mentioned in Div C Rules either, but since "other" moraines are mentioned, maybe div C is usually expansion of the standard rules. I am coaching Div B.

Since neither are explicitly mentioned, your students shouldn't spend a lot of time learning about them, but be aware event supervisors occasionally branch out from what's explicitly listed on the rules in their tests. For example, h, n, and r channels could fall loosely under glacial hydrology

Like what UTF said, I think it’s good to have the knowledge, but as far as notes, if it isn’t in the sheet or very closely related, it’s just better to learn the idea, because chances are it may pop up again when doing a test with it. Anything goes, and this is a common axiom with every scioly test and lab event.

Well, what you can do, is just download a full set on the text archive.

Are there any guides on how to read glacier maps and diagrams? I feel like I struggle in these questions and I need to learn how to manage them.

What type? Topographic maps?

Those as well as the diagrams of a glacier with fill in the blanks.

Just go online and take a look at all of them you can find. You'll get the general concept of them, and memorize the common ones; most of the fill in the blanks are just diagrams found online with certain parts whited out,
