We left the parking lot around 1 pm and it took about half an hour to get there. The reserve was open grassland area that consists of variety of wildflowers and Stonehenge around the trail. It was a beautiful area except it was cloudy with very very strong wind. I thought if we were there at the right time, the view would be unbelievable. It was so windy and everyone had hard time listening to Dr.Paul and taking picture of the plants. The wind got little better after an hour or so. We also took picture at the top of the giant rock mountain. I realized that serpentine soil holds extensive amount of wildflowers during the spring and overall we enjoyed the trail.

It has variety of habitats of woodlands, coastal shrubs, wetlands and grasslands perfect for hiking or walking dogs. There were great amount of poison oaks on the side of the trail that had to be looked out for. The overall trail difficulty was moderate since there were some big slopes in between. There were great amount of new flowers we learned at this field trip. The tidy tips, pineapple weed, blue eyed grass, shepherd’s needle were some of the flowers we have encountered.

We left on time around 1pm at the parking lot. This field trip was quite a drive that it took longer than the others. There was a giant hill right at the beginning of the hike that completely burned my thighs. There were many poison oaks on the side of the trail, so we managed to stay inside of the trailroad. We saw many wildflower plants that we haven’t seen in the previous field trips. My favorite one was the pineapple weed because it really looks like a mini pineapple. That was the first time that I actually agreed on how they named the plant. I wish the weather could be better since it was cloudy all the time.
