The San Andreas Fault Field Trip
What:
To identify and determine the relationships among the common rock
types found in So. CA San Andreas Fault area.(This trip will follow
lessons on Earthquakes, volcanoes, and rock identification. As we
progress, in the earth sciences unit in Int. Science II). Students
will examine rocks using hand lens and classify them based on prior
knowledge (pre-trip lessons). They will draw relationships of various
geological formations/processes. They will at the end of the day describe
the geologic history of the region (inferred)).
When: Spring 2001.
Who: Int. Science II Students (10th graders).
Why: To practice rock identification skills and sharpen understanding of how geological processes shape the Earth's surface (also to appreciate nature's forces and its underlying energy -this definitely reinforces our semester theme: "Energy"!!!).
Where: San Bernardino Co., CA, near San Andreas Fault.
How:
1. My own research of the area. Contact University geologists, USGS, maps, and Roadside Geology of CA.
2. Determine field trip route and stops (I'll first explore them).
3. Write a grant proposal (compasses, rock hammers hand lenses, transportation)
Field Trip Outline:
- At least 1 site for each of the following: igneous, metamorphic, sedimentary rocks.
- A "panorama" vista point.
- A site showing dike (cross - cutting), fault line, and tilting (if applicable).
- Each student will have a field note packet w/ guiding questions for each stop. At the end of the day, they will have a chance to gather all of their observations and write a brief summary of the area's geologic history. Rock samples will be used in future lessons.
