The Idaho Chapter was first chartered on October 19, 1985, and has had a strong history of involvement in Idaho teacher education workshops as well as the study of and work on the Lewis and Clark Trail. It is one of 35 chapters affiliated with the Lewis & Clark Trail Alliance and has hosted an Annual Foundation meeting in 1990 and in 2010.

Each Chapter charges a membership fee, which generally includes a local Chapter newsletter (membership to the Lewis & Clark Trail Alliance is usually not included in a Chapter membership).

The Lewis & Clark Trail Alliance, headquartered in Great Falls, Montana, was formed in 1969 (and originally named the Lewis & Clark Trail Heritage Foundation) as a result of a US Congressional Commission recommendation to form a non-profit organization to preserve the story of the Lewis & Clark Expedition and the route it traveled. As our parent organization, the Alliance oversees the general operation of the local Chapters and Regional Meetings, helps coordinate preservation of the Lewis & Clark Trail, and sponsors the annual meetings that are held in various historical locations throughout the US.

The LCTA charges a separate membership fee, which includes two quarterly publications: The Orderly Report newsletter and the We Proceeded On magazine. You must be a member of the LCTA to receive these two wonderful publications.
