Narrative:
We left USF around 1 pm on Thursday 4/19. The weather was sunny and warm. It took us around 25 minutes to get to Ring Mountain. This site was surrounded by gorgeous views of San Francisco and beautiful luxury houses. The hike was not too intense and was enjoyable. We did not get to see the famous Tiburon mariposa lily, however we were able to study some new plants and review some old ones that we had observed in other sites. There were also a variety of insects and lizards in this site that hid behind the rocks. Overall, the hike was interesting and the views were stunning.
