About PitWatch

PitWatch.org is the Web version of PitWatch, a print periodical previously published by the Berkeley Pit Public Education Committee for the purpose of educating Butte residents, students and visitors about the Berkeley Pit and related issues. The Committee welcomes your questions and comments.

PitWatch introduces concepts essential for understanding the science of the Berkeley Pit, including its geology and hydrology (water). History, research, and news related to the Berkeley Pit are also available. Our committee members contribute to the PitWatch blog to share our perspectives on current projects, findings, and conclusions related to the ongoing management of the Berkeley Pit.
