Indians are buried everywhere from Mugu Lagoon to Malibu Creek. Every bulldozing operation brings their bones and artifacts to light, as one did just across Broad Beach Road from us - a dozen huddled skeletons, four or five hundred years old, talking no notice of their noisy resurrection. Our germanium garden, falling to Encinal Creek, is sure to be a burial ground, the gofers tell us. Mary Austin writes of the residue of personality that always haunts a place once inhabited by man. Jeffers' poetry is full of these hauntings. But I cannot say that I have encountered sprits here on the Malibu. Perhaps the diesels drive them away. I have no fear of them however. The Chumash were a gentle people, living on shell fish, roots, and acorn meal. We who are carnivorous may leave a different residue. Sometimes I wonder who will follow us here, and what they will make of our artifacts - books on discs ... and less tangible, though perhaps more lasting, our love for this marine mountainscape this world called the Malibu.
