This reservations-only Thinkwalks Natural History tour will include:
- 2 hours of walking, presentation and discussion about
- Waterways that once flowed in Hayes Valley & Civic Center
- Waves of population shifts in the neighborhood
- Sand dunes, rock strata and old maps
- Groundwater research!
What is now the city’s center was once the edge of town. There was a large marsh right beside Market Street that emerged from the underground Hayes Creek. We’ll discuss and explore the creek landscape as it exists today and as it did when this part of the city was built.
As always, we’ll talk about how the city came to be what it is today: a natural landscape deeply influenced by human activity and politics.
