Taxonomic list

• shown as SW of K-5 on large map but SE of K-6; the latter therefore puts it across the county line in Natrona County
cannot be correlated with standard Buck Spring section (K-5 area), apart from occurrence of DR Stratum
not the same as either CM loc. 1039 (K-5 area) or Guthrie's Locality 3 (UCM loc. 81029, "Dark Red Stratum")
