The mountain's name was officially adopted in 1957 by theGeographical Names Board of Canada.[3]
Like other mountains in Banff Park, Mount Erasmus is composed ofsedimentary rock laid down from thePrecambrian toJurassic periods.[8] Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during theLaramide orogeny.[9]
