Reconnaissance Geologic Map of the Central Boundary Waters Canoe Area Wilderness

Abstract

This map was created by PRC students under the guidance of Mark Jirsa, Minnesota Geological Survey, over an eight day period between August 7-14, 2011. The purpose of the map was to build upon and improve previous geologic mapping (e.g., Jirsa and Miller, 2004; Jirsa et. al. 2011). It was also done to re ne contact locations and locate sheer and fault zones amongst the Knife Lake Group, the Newton Lake Formation, Basswood Lake granodiorite and associated sheared rocks. Reconnaissance-style shoreline mapping was completed by students along a 44 mile traverse through 22 lakes and includes 240 outcrops in the central Boundary Waters Canoe Area Wilderness.
