Location: Ring Mountain: 37.9099° N, 122.4858° W; Elevation: 604 Feet

Ring Mountain is on top of the Tiburon Peninsula and has one the most beautiful views of the city. Ring Mountain is known to have serpentine soils, limiting the available species on this mountain. The Tiburon Mariposa Lily can be found on this mountain and only on this mountain. With its open fields and beautiful views many hikers come to this mountain to relax and enjoy this site.

Layia Platyglossa is a dicot, annual herb that is native to California. It has typical Asteraceae characteristics of ray flowers and disk flowers. However, the defining characteristic is the two-colored petals. The petals on this flower have a lobe-like tip that is white while the rest of the petals and disk flowers are yellow. The leaves are green and usually linear to lanceolate. These were scattered all over Ring Mountain. The maximum height is 2 feet.

Information About Our Trip

We left USF around 1:00 pm and the weather was really warm, around 60 degrees. This area is breath taking with its beautiful view of the city. The people that live in those homes there must be rich because they were gorgeous and huge with a beautiful height. I was honestly stressed out during this field trip because I had an evolution exam right after so I couldn’t really focus on what was going on. However this hike was really just about reviewing past species we’ve seen so it was a really nice hike to get my mind off of my exam.
