Near Source Lake an exposed breccia zone in metavolcanic rocks contains pennanite crystals.
Note: There is some confusion with this locality as Cannon (1975) lists it as being along "Guye Creek" which is not a named creek in the area. He was likely referring to the headwaters of the South Fork of the Snoqualmie River.
