Antique Map Auction Sale No. 115 - closed 6/21/2006
Carl Wheat hypothesizes that Capt. William Ludlow (1843 - 1901), Corps of Engineers, was assigned the task of surveying the road from Carroll, Montana on the Missouri to Fort Ellis near Bozeman as a reward for good service, since it allowed him to inspect the wonders of Yellowstone without a furlough. These three maps were produced to accompany Ludlow's official report. In his report, Ludlow says "My own interest in this land of wonder is so keen as to lead me again to hope that it will be protected from the vandalism which it has already suffered, and that the suggestion of an accurate topographical and geological survey, to complete the work so well inaugurated by Professor Hayden, may be made the subject of favorable consideration and recommendation by the Chief of Engineers."
