The Marin Headlands is a hilly peninsula at the southernmost end of Marin County California. It is located just north of San Francisco across the Golden Gate Bridge. This place has beautiful view of Golden Gate Bridge and downtown skyline. The trail was not very hard, but it had some incline and long zigzag trails. This was where the filed quiz was taken so it wasn’t easy for me to take time and look around. The variety of plants such as lupinus, coffeeberry, and other flowering plants were there living in habitat of grasslands and coastal scrub.

We left the school at 1pm and arrived in 20minutes. It was a field quiz day and I was keep looking at notes on the way. It was surprising that the weather is good, despite the fact that it was raining all week. We looked at about 55 species (including the bonus questions) and got out little early about 30minutes. It started to rain again right after we arrived at school.
