Ashworth, A. 1999
Climate Change in North Dakota Since the Last Glaciation: Review of the Paleontological Record. North Dakota Academy of Science 53:171-176.
Sites discussed: Spiritwood Lake, Moon Lake. Reviews several pollen records from across North Dakota (including Moon Lake). Mentions bison remains found in Spiritwood Lake basin by divers. Based on horn core dimensions, Ashworth suggests that these may be from an extinct form (Bison bison occidentalis) and hence may be associated with a mid-Holocene lower lake level (but no radiocarbon dates reported).
