The historical Berkeley Pit in Butte, Montana was developed during open-pit mining of polymetallic veins that overlie a porphyry stockwork vein deposit at depth. The veins are hosted in the Butte granite, one of many granitic phases of the Boulder batholith. View is to the north-northeast.

Pioneer Mountains metamorphic core complex – gray peaks (middle) are in the lower plate that is separated by a detachment fault on both sides, overlain by Ordovician through Silurian yellow metasedimentary units (right and middle left) that make up the middle plate which is separated by another detachment fault overlain by later Paleozoic units (left).
