Northern Prairie Wildlife Research Center
Prince Paul's expedition represented the second scientific expedition through Montana. It is believed that Prince Paul ascended the Missouri River to the Three Forks and then crossed over to the Yellowstone River and returned to Fort Union and subsequently back down the Missouri River. Prince Paul apparently collected a variety of plants and animals on his expeditions and recorded his observations of wildlife and habitats in great detail. Unfortunately, his notes were not published at the time of his death (1860) and remained lost until 1928 when they were found at the Royal State Library in Stuttgart. Before historians were able to publish Prince Paul's journals, all was lost in a World War II bombing raid on Stuttgart.
