Here are some shell and rock art collage pieces I made today. I love walking on the beach and finding interesting shells and rocks. There are a lot of Pacific oyster shells and some volcanic rock here. There is a sea shell midden (A midden is the archaeological term for trash or garbage heap) from the native people on one end of the beach and it is interesting to see all the broken sea shells that they dumped there over the years. It is about 10 feet high. But most of the shells and rocks I use are from the shore line.
