Ge121c: Advanced Field Geology
Instructor: Michael Lamb
TA: Ajay Limaye
Goal: In this course we will employ geomorphic mapping, topographic surveying, sediment size measurements, and sediment transport calculations to investigate landform evolution. The first half of the class will focus on the record of climate change preserved by channel entrenchment on pediments and alluvial fans in the Mojave Desert and Death Valley. The second half of the class will focus on the record of tectonics recorded in drainage basins of the Dragons Back Ridge, Carrizo Plain. We will focus on addressing the following questions: 1) Why are pediments and fans different? 2) Why are alluvial fans entrenched? Is this a signature of the climate change? 3) How do hillslopes and channels respond to a change in uplift?
Post trip activities: We will meet once per week spring quarter to work through the analysis of data collected in the field. Tentative meeting time is Friday 3-5 pm, 267 Arms.
Deliverables: 1) Field notebooks. 2) Geomorphic maps from Death Valley and Dragonís Back Ridge. 3) Digitized data (Excel) from channel and sediment-size surveys. 4) Data analysis results (to be completed as a group after the trip).

Required Readings (read before trip and bring on trip!):
Other useful Readings:
Logistics: We will map for a total of 9 days. The first night will be camping in a remote area of the desert with no facilities. Day 2-5 will be in a campground with toilets and water. Days 6-9 will be in a campground with toilets but no water.
The GPS Division will provide group camp gear (stoves, lanterns, tables, chairs, water jugs, ice chests, pots & pans, dishes). We also will bring measurement gear (hand levels, measuring tapes, pebble count tapes, stadia rods, shovel, field books, maps, gps, laptops, colored pencils). We will shop for food together on Day 1.
Students are responsible for their own field equipment. Please also bring your personal copies of the required readings. You may choose to bring your own laptop for calculations.
