Islais Creek Former Urban Reach

[Islais Creek](https://en.wikipedia.org/wiki/Islais_Creek) was once one of San Francisco's major watersheds, but most of its lower urban course has been culverted, narrowed, or filled. Only fragments remain daylighted, while the former creek and wetland system can still be inferred from the valley floor, infrastructure, and the interpretive focus at the surviving channel near the bay.
