N. Clark writes to portablerockart.com: "Two years ago, I started to find rocks with carvings of animals, showed them to family and friends and to the local archaic rock expert. Same response. All nature made. Until I showed them to this friend who saw what I saw. I do not have any archeological background. I just like rocks, appreciate beauty, creativity. I am looking at them with an artist's eye. I have been totally amazed by all the things I have seen and have been thinking: This is a BIG puzzle! (Nothing in the specialty books around here could give me a clue)."
American anthropology must begin to formally, rigerously, evaluate anomalous finds in a scientific manner or they risk losing credibility with their public constituency by lazily explaining all of them away as "lusus naturae."
