Miller. Four students along with a TA and Dr. Miller mapped the southern shore of Lake Three of the Boundary Waters Canoe Area Wilderness, Lake County, Minnesota in order to establish a better understanding of the contact relationships of the Anorthositic Series of the Duluth Complex and the Lake Three Troctolite which is a discrete unit of the Layered Series of the Duluth Complex. Building on previous shoreline mapping (Miller, J.D., 1986), several traverses inland were completed to determine the extent of the Lake Three Troctolite, establish the contacts with the Anorthositic Series and describe the internal structure and lithology of the Lake Three Troctolite. Based on the four days of field work this 1: 10,000 scale map and cross section were produced for use in future research projects.enPrecambrian Research CenterUniversity of Minnesota Duluth2013 Precambrian Field CampMap
