This pond rests atop the San Andreas Fault, causing an indentation that later filled up from an underground spring. Unfortunately, the water isn't easily visible due to the overgrowth of cattails in the area. Nonetheless, it remains a beautiful natural spot worth the effort to explore.

Highest point with a view across Palo Alto, Stanford, the Silicon Valley, and across the Bay. Note the Kaiser Permanente limestone quarry right below, ringed on the south by Permanente creek: Kaiser started it in 1939 and it gave the name to his business empire and the hospitals til today.
