The Butte Archives has a large historical collection of complaints about the underground mining and the open pit mining in Butte. Join us at noon on Wednesday, April 12, as David Armstrong talks about the Dave Piper Collection which documents subsidence complaints in Butte. His talk will focus on the area bounded by Utah Avenue on the east to the Travona Mine on the west, and from Front Street on the south to the Emma Mine on the north. This area was primarily impacted by mining at the Emma Mine and Travona Mine, mainly around the time of World War II.

After working for several decades in the mining industry, David Armstrong came to Butte to teach at Montana Tech. Since retiring as Head of the Mining Engineering Department, he volunteers at the Butte Archives, the Butte Food Bank, and the World Museum of Mining.

The Brown Bag Lunch will begin at noon and run about an hour at the Archives, 17 W. Quartz Street. Coffee and water will be served and guests may bring a sack lunch. Brown Bag Lunches are hosted on the second and fourth Wednesdays of every month. For more information, contact the Archives at 406-782-3280.
