High-grade wall

27 November 2010

As you walk up Broadway Terrace from Broadway, you pass the Claremont Country Club and its golf course, then reenter the residential area of Upper Rockridge. At the corner of Country Club Drive and Broadway Terrace is a bus stop and this marvelous stone wall.

The entire wall is faced with local rocks from the Franciscan mélange that underlies Piedmont and its surroundings: high-grade altered chert like this stone, greenstone, sandstone, serpentinite, radiolarian chert, basalt. It slows me down every time I pass. I don’t know where such an assortment was ever quarried. It seems more likely that the stone came from around the neighborhood, maybe even the lot itself. That is exceptional. The next lot also has a wall, but it’s a pale and homogeneous thing made of quarry rock, conventional and boring.

More Rockridge Rocks

Lately I’ve returned to Upper Rockridge in search of the elusive Rockridge Rock. On Bowling Drive I captured this view of Cactus Rock, which perches high above Acacia Avenue. (A reader took the same photo in July 2008.)

Cactus Rock is impressive, but I still have trouble believing that picnic parties would come up there regularly; it’s 1000 feet and almost a 200-foot climb from Broadway Terrace. The climb to “Mount Ararat” would have been shorter; but I still lack evidence that a large rock sits up there.

That leads me to 5920 Broadway Terrace, where the owners have recently finished a major upgrade to the grounds revealing some very impressive rocks. (A commenter mentioned it last year.)

Click the photo for a larger view. You can’t quite see it, but the rock beneath the porch now has a fountain installed that spills in a waterfall over it into a pool. Could this house be sitting on the original Rockridge Rock?
