Cooperating Association

Drawing of covered wagon in Mitchell Pass

The Oregon Trail Museum Association (OTMA) is one of many cooperating associations to be found throughout the United States. Cooperating Associations developed early in the National Park Service history to provide visitors with inexpensive trail guide brochures, pictures, maps, and other interpretive literature not otherwise available through the use of federal funds. Their primary function continues to be the support of park interpretive and related visitor service activities. Cooperating associations operate small bookshops and sales counters in park visitor facilities. These bookshops make literature and other items that assist in the public understanding of the parks available. Monies from these sales are used to sponsor various activities that support the park’s interpretive programs.


Since 1956, OTMA has provided support for both Scotts Bluff and Agate Fossil Beds National Monument. Here are a few ways your contributions support the park:

  • Printed self-guiding trail brochures and other interpretive literature
  • Provides exhibit materials, such as the wagon replicas used on the Oregon Trail
  • Supports living history demonstrations of life on the Oregon Trail
  • Provides park research materials
  • Purchase photographic material to assist interpretive program development
