does it affect the show pack in the Sierras?

6) What did the research find about the difference between the Lyell and Maclure Glaciers in

Your main post is worth 10 points.
For your required two reply posts, make sure that you continue the discussion of the main post you
are replying to by using information from the article.
Your two replies are worth the other 10 points (5 points each).
Once five students have replied to a student’s main post, you cannot reply to that post unless you are
one of the original five and you are conversing back and forth continuing the conversation. This rule is
to insure that all students get at least one or two replies to their main post. Remember that a reply
does not count if you just say things like: “I agree with you”; “I disagree with you”; “I would have said
the same thing”; and so forth! This is a dialog between you and other students based on things you
found interesting, surprising, and/or new from the article. So you can obviously agree or disagree but
you must give reasons, examples, or insight into what you have learned. Think of this as an in-class
discussion if we were meeting face to face. You also must respect each other and be polite!
Make sure to read through and understand the two grading rubrics for discussions. Points are
rewarded or deducted based on the grading rubric so you will need to follow them if you are looking
for all 20 points.
