-------- Original Message -------- Subject: Mystery maps WI, MN, & UP Date: Sun, 30 Jul 2006 19:43:35 -0400 From: Weessies, Kathleen <[log in to unmask]> To: Maps, Air Photo & Geospatial Systems Forum <[log in to unmask]> Some maps landed in my lap (figuratively) and I'm trying to identify their origin. They could possibly be supplements to a federal government document that came through depository in the last 10-15 years, or maybe not. I'm hoping someone from Minnesota, Wisconsin, or Michigan will recognize the following description. 27 color maps on good quality paper, 86cm wide x 58 cm high (33.5" x 22.5") All are 1:1,000,000. Several sheets have footnotes, the newest reference is 1983. The first 18 are made by Envirosphere Company with computer cartography by Northwest Cartography, Inc. of Seattle. Each sheet title of the first 18 is prefaced with "North Central Region" Each plate is in 2 parts: A always shows Minnesota, B always shows Wisconsin and Michigan's Upper Peninsula Plate 1 A&B: Index (revised draft) Plate 2 A&B: Federal Lands (revised draft) Plate 3 A&B: State Lands: State Park Systems, State Wild and Scenic River Systems, State Forest Lands (revised draft) Plate 4 A&B: State Lands: State Wildlife Management System, State Wilderness Preservation System (revised draft) Plate 5 A&B: Highly Populated Areas (revised draft) Plate 6 A&B: Population Density (revised draft) Plate 7 A&B: Water Bodies (revised draft) Plate 8 A&B: Federal Designated Critical Habitat (revised draft) Plate 9 A&B: Wetlands (Revised Draft) Now come some sheets with similar paper, size, and coloring, but because of the sheet numbering duplicating the ones above, I think they must be supplementing a different but related publication. Plate 3 A&B: Overburden thickness in the north-central region Plate 4 A&B: Faults and ground acceleration in the north-central region Plate 5 A&B: Rock and mineral resources in the north-central region Plate 6 A&B: Groundwater basins and potential major discharge zones in the north-central region Plate 7 A&B: Groundwater resource potential of the north-central region Any help would be appreciated.
