Heading west, past Jerry Garcia Amphitheater, soon reached the upper reservoir (third pic), with the usual wet dogs, taking the inner trail next to the water partway round: ducks in residence. A short stairway at the reservoir's north end took me to a third musing station (this a map, fourth and fifth pix) and a Philosopher's Way plaque near the parking area and trail up to the blue water tower (sixth pic).
The westside water tower is encircled by a paved walkway with big rocks to sit on and to-die-for views. Here I came to my fourth, and favorite, artstation of the day (seventh pic), part of which says: "The highest part of the park looks out over a neighborhood of immigrants." Besides the cityviews, you can also look down into backyards in the upper Excelsior neighborhood (eighth pic).
Circling for a while on some isolated middle and southwest-ish openspace and forested trails (pics 9 through 13): Wildflowers, including yellow mustard and California poppies … tall grasses, bees and butterflies … various kinds of beautiful trees. So many inviting trails in this park it's difficult to choose which to take.
On a forested trail just above Mansell near Brazil came upon a fifth mounted infotablet: a 1929 photo of Visitacion Valley residents at "Sandy Beach" … "A collection of moments … "
Have I now seen them all? More about the art stations:
Near the bus stop at John F. Shelley and 1700 Mansell is now another of those colorful new park infosigns (last pic: an old bench here).
