38.0400° N, 122.7400° W: Marin Headlands
We spent the morning hiking in the California county of Marin. Marin is just north of San Francisco, across the Golden Gate Bridge.
Mount Tampalias is a well known and much loved landmark in Marin. They call it the 'sleeping lady' because that's what it looks like. Look at the photo. Can you see the sleeping lady?
The Golden Gate National Recreational Area has beautiful trails perfect for hiking and biking. The hiking trails are quite hilly. One moment you are hiking up a hill and the next moment you are hiking down a steep slope. These rolling hills were caused by the San Andreas fault. This fault is the slippery yet sticky boundary between two of Earth's tectonic plates. It is responsible for the biggest earthquakes in California, up to at least magnitude 8.1.

Notice how the hills seem to have been pushed together, like the wrinkles in a blanket. It's the movement of the North American Plate and the Pacific Plate that are doing the pushing. They push the land together to make 'wrinkles' that we hike up and down. The San Andreas fault is the land where these two plates meet.
Missing my students!
