San Bruno Mountain Watch/Dune Defenders
May 21 @ 10:00 am - 1:00 pm
San Bruno Mountain’s sand dunes formed 100,000 years ago when higher sea levels flooded the edges of the mountain. Join in protecting the native dune vegetation, including an endangered wildflower, by removing invasive weeds!
Meet at Hillside Park (parking at 222 Lausanne Ave, Daly City)
Register in advance.
