Park History Deep in Manure (bike ride)
Oct 2 @ 4:00 pm – 6:30 pm

Thinkwalks presents an exploration bike ride:

Park History Deep in Manure

The Park was built with rich waste from 19th Century street sweepings on what was considered a poor wasteland of shifting sand dunes.

We’ll ride our bikes around to explore and find the oddities… A railroad right-of-way in the Park? A 900-year-old building? A quarry-turned-pond-turned-pregnancy-test-eradication-zone? A living fossil third species of redwood (coast redwood and giant sequoia being the first two)? Yes, amazingly, all of the above.

We’ll also see historic photos at the sites of… A mini Brooklyn Bridge? The ship that found the Northwest Passage? A virtually unknown plan for a superhighway from 1928? Yes, true!

Ride without rush, appreciating how the dunes became today’s lush garden. We’ll unearth how the Park was made, and make it more ours.

⭐ Rain or shine

Living in the Plate Boundary

Superstar Geophysicist Tanya Atwater, will present an incredible and amazing series of images and ideas on the geologically active San Francisco area. She’ll also throw in some climate-related stuff because it’s amazing.

Tanya is a retired faculty member from UC Santa Barbara. After the initial theories of plate tectonics were established, Tanya was deeply involved in completing the theories. Her early papers on the topic were incorporated directly into text books and set the standard for geology education. She also is well known for using animations as an educational tool. More animations.

Sky Phenomena

Joe Jordan will come back with new material after having really wowed and inspired us with his slides on this topic in 1997.

Joe is the kind of excitable guy who, when he sees the conditions are just right for unusual cloud formations at the North Pole, hops on a specially instrumented plane commandeered from NASA just so he can go photograph and study them. (Well, he did, back when he was working at NASA Ames.)

Joe has recently focused his attention on energy planning and will regale us with some details of that project as an added treat.

Ice Plants, Mattress Wireweed & Other Onslaughts

A talk at the Randall Museum

Ice Plants, Mattress Wireweed & Other Onslaughts

Lew Stringer of the Presidio Trust and formerly with the Golden Gate National recreation Area (GGNRA) will give us a presentation about the creepy plants that seem to be creeping all over the place. Invasives aren’t 100% evil. They’re 100% complex and give a real challenge to restoration efforts in the parks.
