North knocker, Mountain View Cemetery

30 April 2008

knocker

Continuing my inventory of the knockers of Mountain View, this is on the far north end of the cemetery, along the lowest of the three roads back there. It appears to be the coarse, tough sandstone—technically a metagraywacke—that makes up the majority of the Piedmont block. I can’t always tell what a rock is at the cemetery because I can’t whack it with my hammer. Don’t you try that either.

Managing the lake

Lake Merritt needs a lot of care and attention to perform at its top level. This view of the pergola at its east end shows one of at least three aeration fountains in the lake. Without the oxygenation provided by these fountains, the organic matter brought in by the tides and streams, and deposited by the abundant bird population, would periodically overwhelm the natural oxygen dissolved in the water and turn the lake into a stinking anaerobic pond.

Without upkeep, this site would quickly revert to the tidal marshland that it once was. That would be nice in its way, but city-dwellers would probably complain about it. Click the photo for a postcard-type view of this end of the lake taken last weekend.
