Narrative:

We left USF around 1 pm on Thursday 5/3. The weather was sunny and warm. It took us around 30 minutes to get to the upper section of Mountain Tamalpais. We hiked in the lower section this time and climbed down a 10 feet ladder in order to cross to the other side. This site was surrounded by gorgeous views of water and there were a variety of wildlife present such as salamanders and lizards. The hike was downhill and uphill and we got to review many of the species and learn new ones.
