Points of Interest

In this video, John Fournet of the San Francisco Public Utilities Commission explains the origins of the Pulgas Water temple.




In 1934, the first rush of Hetch Hetchy water flowed through the gravity-driven tunnel system, across the California's central valley. It swooshed through the base of the Pulgas Water Temple and into nearby Crystal... More

2. John Fournet, San Francisco Public Utilities Commission

Our guide for the day, John Fournet, is the Community Liaison for SFPUC Natural Resources and Lands Management Division.

Ringing this blueschist bolder is Dipsacus fullonum, or Common Teasel. This non-native, thistle-like plant has been used for combing out... More

This view from the top of the hill is no ordinary vista. The body of water is Upper Crystal Springs reservoir, one of several that holds San Francisco's drinking water. The San Andreas fault runs through the valley under Crystal Spring. This means you are standing on the North American tectonic plate (which is moving south) and looking across the ... More
