Ring Mountain Geology and Wildflowers

Ring Mountain Geology and Wildflowers
Saturday, May 30, 2026, 2:30 to 5 pm
Leaders: Nicole Myers and Kristin Jakob
Please sign up for this field trip on Meetup.

Join geologist Nicole Myers and botanist Kristin Jakob for a late afternoon ramble on Ring Mountain in Tiburon. Learn how the amazing and unique geology of this mountain is the basis for its landscape, rocks, and soils. We will see the relationship between these landforms and the plant communities that they support.
Geologic highlights are serpentinite outcrops and metamorphic rocks of basaltic origins in the upper portions and sandstone and shale formations on the lower slopes. The nutrient poor serpentinite supports rare plants like the Tiburon Mariposa lily and Marin dwarf flax. Along our route, we will encounter an array of native plants and flowers depending on weather. Wavy-leaved soap plant blossoms start opening about 4 pm, which will make our descent from the mountain enchanting.

Directions:
Meet at the end of Westward Dr. off of Paradise Dr. in Tiburon (near 208 Westward). We will connect with the Phyllis Ellman Trail part way up.
