The Butte-Silver Bow Public Archives will continue its Brown Bag Lunch series on Wednesday, July 26, with a presentation by Kaleb Scarberry about the volcanic activity that shaped Butte’s landscape. Scarberry is a field geologist/petrologist with primary interests in igneous processes, including volcanic deposits and ore formation. He has worked at the Montana Bureau of Mines and Geology for 10 years and enjoys the work. His work involves geologic mapping, rock sampling and bulk geochemistry, and geochronology for quadrangle-scale field studies. Scarberry holds a B.S. in Geology-Anthropology (Minor) from Central Washington University and graduate degrees in Geology from Idaho State and Oregon State Universities.

The presentation will begin at noon and run for about an hour at the Archives, 17 W. Quartz. Guests are encouraged to bring a sack lunch. Coffee and water will be provided. Brown Bag Lunches are held on the second and fourth Wednesdays of every month. For more information, contact the Archives at (406) 782-3280.
