Sand mining in San Francisco Bay is a little known industry that has existed since the early part of the 20th century. Come learn about this activity that occurs in the deep subtidal areas of the Bay and provides sand for construction projects throughout the Bay Area. The talk will include some of the latest science, a discussion of mining effects on the marine environment and outer coast beaches, and a look at known concerns about sand mining. Ten-year permits for mining have recently been issued, so it’s a great time to understand the efforts and advances being made in the science and industry of local Bay sediments

JULY LECTURE NOTES -- SEEP CITY
http://sfnhs.com/2015/08/15/san-francisco-citys-seeps-springs-and-assorted-creeks/

Joel spoke at the Exploratorium on July 15th, 2015 exploring in conversation and images “Seep City” – a catalog of water discoveries in the city of San Francisco.

Joel’s map of Seep City shows today’s landforms, but overlays the springs, water, and waterways of the past (I like how the map is a lacking in any streets — makes it funner to try and identify the places you know). Crissy field used to be much larger (the current marsh is a “sculpture of a marsh”), and there were large marshes on the eastern side of the city, a tidal waterway running up to the Mission District, and Islais creek wending it’s way into the peninsula. The sands also held many temporary lakes and water ways that would come and go with storms (and the shifting sands). They are barriers and dams, but could be blown away in a storm. Creeks flowing out of the dunes were often temporary or seasonal...
