Preservation Training

If you don’t know where it is you can’t preserve it! Resources for mapping and marking our nation’s emigrant trails so we can protect them are available here. Preservation activities occur at the chapter level, and are driven by people like you – people who are excited to get out on the trails and who are interested in acquiring the skills and knowledge needed to preserve our country’s emigrant trails.

Take a look at these resources and make sure to contact your local chapter's preservation officer to learn more about how you can get involved in preserving trails in your area!
