Themes of the Week:

The geologic themes this week include the roles of glaciers, rivers, volcanoes, and earthquakes in shaping the Pacific Northwest in recent geologic time.

To fully explore these themes you will:

• Discuss how a boulder from elsewhere can be placed onto a landscape by natural geologic processes, and in particular discuss how to recognize whether a boulder was placed by either a glacier or by an iceberg that floated to the area on a glacial lake outburst flood.
• Estimate the current level of earthquake hazards in your neighborhood.
• Describe the current volcanic hazards to your neighborhood.
• recognize and distinguish avalanches, glacial till, stream sediments and lahars
• Recognize moraines as indicators of previous glacial advances.
• Analyze another unconformity, this time a real one.
• Outline the similarities and differences between the effects of the Holocene and Pleistocene epochs on the geology in the Pacific Northwest.

By completing the following:

1. Read Lecture 2-The Quaternary period in the Pacific Northwest, Pleistocene ice ages to present and its linked Basics and Focus pages and refer to them in your assignments.
2. Participate in the Week 2 Discussion in the online classroom. See Weekly Discussion Rubric
3. Read Week 2 Lab Assignment. Complete Lab Assignment #2 by:
   1. submitting the Lab #2 answer form in the online classroom
   2. completing and mailing, via postal mail, the two images that you have printed and labeled
   See Lab Rubric
4. Take Quiz #2 in the online classroom. See the Weekly Quiz Rubric.
5. At the end of the week, compose a summary of the main things you learned about the geology of the Pacific Northwest and post it in the online classroom Week 2 Summary. See the Weekly Summary Rubric.
