U.S. Geological Survey Circular 1190


First printing: October 1999
Second printing: February 2000
Third printing: September 2003 (with a revised map on p. 11)
Circular 1190   This Circular describes the Central Great Lakes Geologic Mapping Coalition. The plans developed by the Coalition provide a new model for State-Federal collaboration in research, information delivery, and outreach, as well opportunities for collaborators to work more closely with the various information-user communities. Although this Circular deals primarily with the geologic foundation for sustainable growth, the program it describes will also serve as the cornerstone in a new integrated science effort that will focus all of the capabilities of the USGS (biology, geography, geology, and hydrology) to address societal needs in the Central Great Lakes region.

The text and graphics of Sustainable Growth in America's Heartland: 3-D Geologic Maps as the Foundation are presented here in two versions: a 72-dpi PDF [1.4MB] and a 150-dpi PDF [3.9 MB] suitable for printing. If you are connected to the Web through a modem, you should be aware that it may take some time to download the larger file.
