 The most accurate and comprehensive account of the expedition was produced by Aubrey L. Haines, the Yellowstone National Park historian in 1965 when he produced "The Valley of the Upper Yellowstone" which was masterfully reconstructed from all the previous fragmented accounts.The Cook–Folsom–Peterson Expedition did not name any park features discovered during the expedition that have persisted to the present day.In their journals they did refer to many features incorrectly (based on incomplete or inaccurate maps made from previous accounts), thus causing some confusion that had to be sorted out by later explorations and surveys.
