Gardens Granite

One of the most characteristic features of The Gardens area is Gardens Granite, now called Gardens Granodiorite. It is this stone which provides the grey backdrop on which the contrasting orange lichen grows. Some tourists from San Diego told me that the lichen is a good indicator of water quality - they have not seen it in San Diego for some years.

The Gardens Granite plus the white sand are the dominant geology of the area. Soil is not deep and close to the beach is pretty much non existant. At The Gardens house, my parents grew vegetables in pots in a small glass house.

I've added a link to the official Stratigraphic entry on this stone. It's not the most rivetting piece of prose, but it's yet more evidence of the unique nature of The Gardens area.
