Sample Week-long Timeline from February 2011
Homework Policy
Homework is due on the day listed below. Late homework will be accepted, for half credit, for one week past the due date (i.e., through the following Weds). Late homework will not be accepted after one week past the due date, unless the instructors ok it ahead of time.
ASSIGNMENTS
Dates listed are the due dates.
Friday January 13
Look over the beacon search diagrams (we will practice during lab).
Read McClung 90-91 (Snow Slab Nomenclature), and McClung 109-118 (Avalanche Terrain)
Homework 1 due
Wednesday January 18
Read McClung 21-36
, Elements of Mountain Snow Climates and Weather. You can skim pp 26-29, focusing again at the Local Wind Flow section
Homework 2: MetEd module: Avalanche Weather Forecasting. Complete module, take quiz and print it out to hand in.
(Give yourself a couple hours for this intro, it's a bit a long). Feel free to skip or skim cases 4 and 5 in the Forecast Exercises near the end.
Timeline Part I due. Check out this Sample Week-long Timeline from February 2011 for guidance on formatting. You can find links to the CLN and AMB data sites on the Mesowest network under the Resources section of this website. The key from the in-class exercise can be found above under the "Timeline Stuff" section.
*optional: Read Atwater, "The Avalanche Hunters," chapter 2. This is a fun chapter by one of the legends of the avalanche world, Monty Atwater. It's a good introduction to avalanches and snowpacks, and has some fun Alta history.
Friday January 20
Read AAA - Snow, Weather and Avalanches Sections 2.1-2.5 (Snowpack Observations)
Read AAA - Snow, Weather and Avalanches Appendix F. Recommend you print this appendix for easy reference if you are reading it online.
Reminder: this book is available online here if you didn't end up buying it
Wednesday January 25
Read McClung 36-40 (Heat Transfer)
Read Cline 1997 (Surface Energy Balance, Heat Transfer in the Snow Pack)
Read Ahrens 10-12 (Atmospheric Pressure) and
Ahrens 91-95 (Water Vapor)
Lab 1 and Pit Profile 1 due
* All labs include a full pit write up like we practiced in class for the pit you dug during the field session. Refer to the AAA book for more guidance.
*optional: Read Fraser, "The Avalanche Enigma," chapters 2-3 (link under Readings)
Wednesday February 1
Read Armstrong, "The Mountain Snowpack"
Read 95-98 (Dry Slab Avalanche Formation)
Read AAA - Sections 2.6 and 2.7
Know AAA Appendix F inside and out!
Lab 2 (including pit profile) due
*Practice for beacon test*
Friday February 3
Beacon tests!

Atmospheric Snow Crystals Homework due. We will talk about this more in class, do your best with the readings that were due last week.
Wednesday February 22
Exam 1
Pit Profiles Due
Wednesday March 1
Watch Inclined Plane Force Components.
