One night in 1981 Doug Richmond and Tom Pratt decided to offer an avalanche class at Montana State University for both students and people living in the community. Seven nights of lectures for $7. At the time a beer was a dollar, and they figured each lecture was worth a beer. Now, 33 years later, we only charge $30. The class has four lectures over two nights followed by a field day just out of bounds at Bridger Bowl which has been a supporter of the class from the beginning. In the last ten years, we have taught this class to more than 3,000 people. It is called Introduction to Avalanches with a Field Session.
