If a horizon is taken to be "a primarily spatial continuity represented by cultural traits and assemblages whose nature and mode of occurrence permit the assumption of a broad and rapid spread" (Willey and Phillips 1958: 33), then Wallace's archaeological cultures are not, strictly speaking, horizons. While Warren's 1968 article failed to resolve the problems of horizons, Warren (this issue) does make the useful observation that Wallace's (1955: 228) brief discussion of southern California coast cultural development was one in which horizons became very much like stages of cultural development.
