Natural History

A Reference for Ecological Restoration

Before the City of San Francisco was fully built and streets and parks were lined with trees, San Francisco was a rich mosaic of grassland hilltops, rocky radiolarian chert outcroppings, rolling sand dunes and hundreds of creeks, springs, lakes, and wetlands. Take a look at these images to get a glimpse of what natural history has to share about San Francsico. 

 
 

About These Photos

A collector who wishes to remain anonymous selected these historical San Francisco nature images. The complete collection can be found at OpenSFHistory and may be the greatest in private hands, amounting to over 100,000 negatives and prints. 

Thanks to OpenSFHistory, a project of the Western Neighborhoods Project, for sharing these images and those from similar private collections, with the world!
