Thinkwalks presents an exploration hike:
Hike Our Most Hidden Watershed
San Francisco’s first major reservoir started as a natural lake and again has become just a lake.
An empty Laguna Honda Reservoir after the 1906 quake.
This watershed on the west side of Twin Peaks near 7th Avenue has been through a lot. Sewers flow under the deteriorating concrete bottom of the abandoned reservoir at Laguna Honda. Muni Metro trains run under the creek. We’ll examine the secret back woods of the watershed where no official trails go. Recently, renegade trails have been appearing.
Highlights: springs, hidden tributaries, dunes, private neighborhood, WWII Victory Gardens, rail tunnel vent, SF’s first imported water aqueduct, water for Golden Gate Park, early development, artful hospital detritus.
Be prepared to visit sandy or muddy remote places, some not on any known map.
