Ochre mineral pigment sources in the Kenya Rift Valley Sampled in 2012 for Zipkin's dissertation research project. Each entry represents a sample of ochre collected. Each sample has a unique identification code beginning with the prefic "KEN". Multiple samples were often collected from the same source in order to assess intra-source chemical variability. Source names are associated with each waypoint.
