Ask a Scientist: SF’s Primeval Waterscape – 12.09.09

by Eric on December 9, 2009

Christopher Richard, Curator of Aquatic Biology, Oakland Museum of California, will be the featured speaker at this month’s Ask a Scientist. He’ll be describing San Francisco’s long-vanished watershed environment:

Did you know that the southeastern portion of San Francisco was once dominated by the watersheds of two large creeks, Mission and Islais, while large parts of the north and west of the city had no creeks at all because they were covered with sand dunes? Our waterscape has changed dramatically over the years, from the natural creek- and dune-scape to today’s modern sewersheds. Come learn about the unique features of San Francisco’s primeval waterscape and find out how the city used and abused its many creeks and lakes as it grew into the modern metropolis we call home. The Oakland Museum of California’s Christopher Richard will explain the geological and political history of this transformation and will take us on a virtual tour of the remaining free-running creeks in San Francisco (which you can visit!).

Ask a Scientist takes place at 7pm at the Axis Cafe, 1201 8th Street (btw. 16th & Irwin) San Francisco. Admission is free, but come early for indoor seating. Some (cold!) outdoor seating may be provided, weather permitting.
