1. Watershed History Marker

Inscription. Historically, the underlying soil of the North Shore Watershed was primarily sand with serpentine outcroppings. The basin's shoreline and soil composition changed when large sections of Yerba Buena Cove (now the Financial District), Fisherman's Wharf, and the Marina District were filled in with sand, bay mud, and urban rubble to make new land for development. Because of urban fill, substantial sections of the North Shore Watershed are subject to liquefaction. The natural dunescape of the North Shore Basin also contained a number of freshwater bodies, though they were rare and their water precious. The most famous was Washerwoman's Lagoon in Cow Hollow, used first for drinking and later for laundry. By 1882, the lagoon was also filled due to water contamination and a cholera outbreak. The North Shore Basin's remaining significant natural areas are located in Golden Gate National Recreation Area, primarily in the Presidio.

4. Cow Hollow, showing Washerwoman's Lagoon

This is a picture of Cow Hollow, showing Washerwoman's Lagoon (the body of water on the left), as denoted and depicted on the marker. The marker photo of Cow Hollow is dated circa 1888, and is virtually the same photo in content, perspective, and lighting as this photo from the Bancroft Library, which has dated it to 1896 - although somewhat confusingly, "1856" is visible on the photo where a date would be expected. (NB: Bancroft possesses the negative.) That the marker and Bancroft photos are one and the same seems fairly certain - if one looks at the Loveland residence in the foreground of the Bancroft photo, the shadow of the chimney and the positioning and amount of ivy growing up the side of the house are identical. The San Francisco Public Library's History Center also has the same photo, and dates it to circa 1866-67. To further muddy the waters, the Bancroft Library has another extremely similar photo by Carleton Watkins, dated tentatively to circa 1857-62. Regardless of the photo date, what remains today of the lagoon is a street name - Laguna Street.
