Mountain Lake Science Saturdays


Mountain Lake Science Saturdays is a lively new series of talks by scientists studying topics relating to Mountain Lake and its ecological restoration. On the second Saturday of every month, gather at the lake to hear researchers from a variety of disciplines talk on topics ranging from Archaeology to Zooplankton. Here’s your chance to ask the experts your questions about the science behind saving this precious San Francisco natural wonder! 


Reintroducing the Western Pond Turtle to Mountain Lake


Come out to Mountain Lake to learn about the local reintroduction of the Pacific coast’s only native freshwater turtle! The Western pond turtle is a threatened species with very little natural habitat remaining, due to development and the growing dominance of non-native turtles. We’ll hear about the benefits of reintroducing this species from Sonoma State Professor Nick Geist, a local Western pond turtle expert, who collected and cared for the pioneer population of turtles planned for release very soon into Mountain Lake.


Nick Geist is a Professor of Biology at Sonoma State University. His research focuses on the evolution of reproductive behavior of reptiles, and current research includes the reproductive biology and conservation of the western pond turtle. He is a collaborator on the North Bay Western Pond Turtle Project with the Presidio Trust and the conservation departments of the San Francisco and Oakland Zoos.

Talks are held at the outdoor classroom (north end of the lake), approximately a 15 minute walk from the parking lot at 14th Avenue and Wedemeyer Street (Free Parking). Follow the signs from there or join a guide leaving at 1:45 pm. Get Directions >>
Second Saturdays aren’t just Science Saturdays! Join your neighbors at Mountain Lake every Second Saturday from 9 am to noon for Service Saturdays. Volunteer and help restore Mountain Lake’s precious natural resources. For more information, email Jason Lisenby at
