Fuzzy sets have previously been applied to photographic target stimuli. In this paper, we use the same technology to construct a set of natural sites in the San Francisco Bay area. We created a Universal Set of Elements containing 13 items which created five orthogonal categories: Buildings, Ponds, Towers, Gardens, and Bridges; 22 sites were identified and were independently coded by two volunteers. Thus, the fuzzy sets that represent these sites are a reasonable consensus of their content. This paper describes the construction process in detail, and the appendix shows each site and its associated fuzzy set.
