Abstract

This map is the result of seven days of field mapping by the authors in 2008, as well as a compilation of information gathered from Van Hise (1901), Gruner (1941), and Chandler (1991). This map was created by PRC Field Camp students under the supervision and guidance of Dr. Dean Peterson, NRRI Senior Research Associate, and Dr. George Hudak, professor at UW-Oshkosh. The purpose of this map is to aid in understanding the nature of the basal contact between the Duluth Complex and Wawa Subprovince Archean metavolcanic-metasedimentary rocks, which was last mapped in the early 1940's. Additionally, this map will serve as a basis for additional undergraduate honors theses studies. Access to the 663 outcrops mapped for this project was provided by extensive canoe shoreline mapping and traverses in the blown-down bush of the Dissapointment and Ima Lakes field area. This map was made at a 1:10,000 scale, and is the first detailed map done in an area previously mapped on a reconnaissance scale.
