Welcome to the Home of the Jammer Trust

The Jammer Trust was founded in 2005 as a Montana Public Benefit Corporation and a qualified 501 (C) 3 educational organization under the rules of the US Internal Revenue Service.

The primary objective of the Trust is to encourage the preservation of historic touring and transportation vehicles that once were used in the National Parks, as well as memmorabilia, photographs and objects related to the operation of those vehicles. The Jammer trust is also committed to making it possible for the public to see and experience what their parents and grandparents enjoyed in the early days of motorized touring in the Parks.

With  the benefit of visitors to the parks, in mind, the trust acquires and restores vehicles of historical value.  Additionally it facilitates the preservation and restoration of historic vehicles by private parties, with particular emphasis on making it practical for owners to maintain the vehicles in as near original condition as possible.

The Trust has worked in close cooperation with the Yellowstone Park Transportation Co. LLC and Glacier Park Transportation Co. LLC, as well as the National Trust for Historic Preservation.  

The principal office of the Trust is located in Bigfork Montana.  Directors live in Nye and Bigfork, Montana, and Garland Texas.

The Trust organizes and sponsors tours in several National Parks, as well as provides vehicles for numerous parades, charitable, and educational events.



The Jammer Trust was pleased to provide vintage touring buses from Yellowstone and Glacier National Parks for the Tournament of Roses Parade on January 1, 2016 for the seventh consecutive year.

One Yellowstone bus and one Glacier bus will be included in the parade for 2016. Thanks to   Barbara Carlsberg of Jackson, Wyoming, owner of the 1925 Yellowstone touring bus and  Sage Olson of Billings, Montana, owner of the 1925 Glacier touring bus. 

The Trust also wishes to recognize Xanterra Parks & Resorts - the nation's premier Park concessioner - as the proud caretaker of the fleets of historic vehicles in both parks and stewards of the environment in some of the world's most beautiful places.

January 1st 2016 marks the first day of Xanterra's stewardship in Glacier National Park.
