Welcome to UC Santa Cruz! We are looking forward to introducing you to some of the spectacular Earth science in our backyard. Over the course of this three day fieldtrip, we will journey from the current plate margin of the North America through the spectacular peaks of the Yosemite Valley to a burbling, active volcano in the Long Valley Caldera.
Your part in this adventure is to become an expert on a specific topic that we will study during the trip. You will team up in pairs and attack one of the topics listed below. When we get to a key location, we will ask you to give a 5-10 minute presentation on your subject. The glacial striations team will present on the polished surface of the Sierran granites, the volcanic dome team will be on a obsidian dome, etc. Remember, you only have 5-10 minutes, so do not attempt to explain everything. Pick a few key points and discuss them. You may find it useful to prepare a handout to focus your thoughts, but this is not required.
We have assembled a few resources to get you started on each topic. You can follow the references in these papers or weblinks to find more. The ISI database server is an excellent source of articles that can be accessed from any campus computer. Also, please use this opportunity to check out the Science and Engineering library, which is just a few steps away from the Earth Science building. If you want to do a topic that is not on the list, please check it through with Profs. Brodsky and Hourigan.
If there are an odd number of people on the trip, we can have one group of 3. A topic sign-up sheet will be available in class.

Logistics
We will be meeting at the Earth & Marine Science loading dock at 6:45 amd and departing at 7 am on Friday, Oct. 5. We will return before 10 PM on Sunday, Oct. 7.
We will be camping in Yosemite at Crane Flat one night and staying at SNARL, a UC-owned reserve, the second night. SNARL provides bunks with mattresses, bathrooms and a full kitchen. You will need your own bedding and towels that night.
Please bring the following items on the trip:
Your own packed lunch for Friday
Comfortable outdoor clothing
Warm hat and warm jacket. (The Sierras are cold at night!)

A job sheet will be going around in class. Please sign up for a job. Everyone needs to sign up for a chore. Driving does not count as a job.
We will cook and eat as a group for the trip. A suggested menu is below. The food shoppers can decide on a different menu, but please be aware of each other's eating issues.
We also need drivers for the trip. If you have some prior experience, please volunteer. We should have at least 6 drivers checked out for the trip. Drivers, please bring your drivers license to Laura Jackson in the front office so that she can take a copy. Also sign on job sheet in class so that we know who you are and can coordinate vehicle pick-up Thursday night.
