If you get the chance to see/read/purchase - An Indian Winter by Russell Freedman - I think you would enjoy it. It covers the 1833-34 Maximilian-Bodmer Expedition uo the Missouri River passing from St. Louis to Fort McKenzie near the present day Great Falls, MT. The signifigance for North Dakota is that it mentions a tribe of Indian I'd not heard tell of before - Hidatsa. It also speaks of the Mandan. It is full of beautiful art work showing Indians in native dress as well as old paintings and sketches of the area. In the back of the book there is a 'places to visit' section that includes - Fort Clark - Mercer County; Knife River Indina Villages - Mercer County; Ward Earthlodge Village - Bismarck plus the North Dakota Heritage Center also in Bismarck. Even though your particular county may not be mentioned, it is a very interesting read. The book I'm refering to was published for Scholastic, Inc for $12.50 new, paperback - which is laminated. While this was published in 1992 - it can be had relatively cheap - even used. The ISBN number is 0-590-48070-7. My copy was acquired through half.com - for 99 cents plus shipping and handling or about $3.50. I was also unaware of the website half.com - but highly recommend it as a way to save money on book purchases. Tim
