A fascinating report written and compiled by Doris M. Wilbur, offering a geological survey of the Baraboo and Blue Mound areas in Wisconsin, illustrated with hand-drawn diagrams and tipped-in photographs, and accompanied by numerous printed topological maps. The work was completed for a summer field course at the University of Iowa taught by noted Professor Arthur C. Bainbridge, who coined the term “sedimentology.”
As per the report’s introduction, the area primarily studied “is about 26 miles in extent from east to west and 53 miles from north to south, including approximately 1145 square miles. This does not include the region studied to the south and south west of the Blue Mounds area but it does include areas only slightly studied on the Dells and Briggsville Quadrangles.”
The report gives a thorough view of the area’s unique geological features, and traces the area’s from the precambrian era to the present. A few of the photographs are commercially-produced photo postcards, but most were likely created by Wilbur. There are also a number of finely-rendered, detailed diagrams and drawings done by Wilbur. In the back of the album there are paper sleeves containing government survey maps showing the Briggsville Quadrangle, the Denser Quadrangle, the Dells Quadrangle, the Blue Mounds Quadrangle, and the Baraboo area. Also included are also photographic-enlargements of certain sections of these maps, which have been hand-colored to illustrate points in the text.
Overall, a unique and compelling geological study.
