Dec 07, 2005 (A Wilson) - The Baltimore Lake Deformation Zone (BLDZ) is located in northwestern Stover Township where it is defined by by a 1.2 km wide, SE-trending zone of folding, transposition and shearing. The BLDZ can be traced fro approximately 6 km southeastward across Stover Township. The BLDZ is characterized by rootless isoclinal folds of bedding/schistosity, sinistral and dextral shear folds, transposition and ductile shear zones axial planr to the folds.

Aug 19, 2013 (A Wilson) - The iron formation is intruded by narrow porphyry dikes and dioritic masses. Multiple units of iron formation are interbedded with chlorite schist and sheared andesite tuff. The iron formation has been traced for a length of 250 ft and has a width ranging from 8 to 30 feet. The zone strikes N55W and dips vertically.
