Ref.:Diabase Dikes of Franklin, NJ, quadrangle, Milton, C.; Jour. of Geol. Vol. LV(6)(Nov 47): 522-526. This locality is only described as at the bottom center of the Franklin Furnace quadrangle and therefore appears to be in Sparta Twp. It is also described as being about 1 mile South of the old Mt Sherman prospect (?). This diabase dike is only 10 feet long and a few feet wide with no surface expression. Host rock is Losee diorite gneiss.
