My secret chert

3 October 2007

If you walk up in Mountain View Cemetery you’ll see all sorts of exotic stone. Nowadays fine stone is a worldwide product. There’s a fabulous anorthosite you’ll see sometimes that comes from Scandinavia. Rapakivi granite too. But I think the older stones include marble possibly quarried across the bay—across the San Andreas fault, actually. Some of the old granite undoubtedly comes from California, whether the Sierra Nevada or the Salinian block in Monterey County. I enjoy all those. But here and there you’ll see stonework incorporating the local stuff, chert and calc-silicate from the Piedmont hill, part of the Novato Quarry terrane in the Franciscan complex. And even more charming is the occasional outcrop, left wild, like this dignified chert.
