The Elk Point Folio, South Dakota-Nebraska-Iowa, by J.
E. Todd, was published in 1908 by the United States Geological Survey.
The Folio was located while searching for Lewis and
Clark and is significant because the Lewis and Clark Expedition covered
this ground 100 years before the USGS, and today we are again looking at
this area. The Folio was located in the Richardson Collections,
Special Collections, I. D. Weeks Library at the University of South
The Elk Point Folio was surveyed in 1898 and illustrates
the river and terrain prior to the damming of the Missouri River. The contents of the Folio include: Descriptive Text, Topographic Map,
Arial Geology Map, and Artesian Water Map. This map covers all
disciplines of the USGS and serves as an example of the work that the
USGS was doing 100 years ago. The Folio was a multidiscipline approach
with a price of 50 cents.
