• Remember that we will be having a field trip this weekend:
  • Leave at 8 am on Saturday April 19 and return approx 7 pm on Sunday April 20
  • We will camp in the Coconino National Forest, dispersed camping (no campground/no facilities) near the Arrowhead Sink, just south of the Wupatki National Monument.
  • On Saturday, we will map the area around the Arrowhead Graben and Sunday we will look at other faults, cinder cones, and the Little Colorado River
  • It is likely to be freezing on Saturday night, so please plan accordingly in terms of your gear
  • Food groups (same as last time) should coordinate for dinner on Saturday and you will need on breakfast and two lunches
  • I will need help on Friday afternoon with the vehicles
• Note that I also suggest reading this paper (and the numerous others on our website and in the references) to help with the final DEM exercise: Wobus, et al., 2006, Tectonics from topography: Procedures, promise, and pitfalls, in Willet, et al., eds., Tectonics, climate, and landscape evolution: Geological Society of America Special Paper, 398, p. 55-74, doi:10.1130/2006.2398(04).

• Some background information is available for last week's lectures from Arrowsmith's Geomorphology course: Look in the middle of lecture 5.

January 16, 2008

• Assignment: Review the basics of Airy Isostasy. Make sure you know and feel comfortable with the concept and math behind this simplest form of isostasy: what sets the fraction of a rectangular block of ice that rises above the water line? You should be able to write a relation for this in terms of the two densities: that of ice and that of water.
  
  DUE at the beginning of class tomorrow, January 17, 2008.
  
  Answers can be found in many Intro Geology text books, in Geodynamics texts, and almost certainly can be found online.
• There is now a 490-level course number: GLG 490 Tectonic Geomorphology - #35523 (3 credits) Registration is restricted to require instructor permission. Discussions with Ramon and Kelin about pre-requisites and preparation is required.
