Mount Barr is one of several magmatic features just north of the Chilliwack batholith. It is part of a large circular igneous intrusion that was placed along the Fraser Fault 16 to 21 million years ago.[2][3] The intrusion is part of the Pemberton Volcanic Belt, an eroded volcanic belt that formed as a result of subduction of the Farallon Plate starting 29 million years ago.[2][4][5]
