Slag Hill is a subglacial mound in the Mount Cayley Volcanic Field in British Columbia, Canada. It consists of glassy, augite-phyric basaltic andesite in steep-sided, glassy, finely jointed domes and one small, flat-topped bluff. The finely jointed domes are similar to those of Ember Ridge. There are quench features at Slag Hill, which is suggesting that the volcanic activity was subglacial. It is believed Slag Hill last erupted in the Pleistocene age.[1]
