MBMG Calendars through the years

For three decades the MBMG has produced wall calendars featuring different aspects of Montana's scenery and culture. As our calendars evolved, a geologic description, an area history, and interesting facts were added to the back of the calendar.

We are always looking for great photos, sketches, and ideas for our calendar, so if you have any photos with interesting geologic facts, send them along and maybe they will become part of our calendar collection.

MBMG 2017 Calendar

Big Butte — Big Butte is part of the Lowland Creek Volcanic field. Volcanoes erupted ash and lava across portions of central and western Montana throughout the Late Cretaceous–Tertiary periods (85 to 40 million years ago). One of these volcanic episodes, from 53 to 49 million years ago, produced the Lowland Creek Volcanic field. This field consists of 340 mi3 of volcanic rock covering 600 mi2 in the hills and peaks north and west of Butte.
