OSTA’s chapters generally support membership and Trail issues in geographic locations where they are formed. Some chapters exist to serve members specific topical interest in the Trail – such as the Descendants and Travelers of the Trail Chapter. Although in the following listing, OSTA chapters are generally listed by their geographic, administrative location, most chapters have some degree of interest in Trail-wide history and issues, or adjoining regions.
OSTA members may choose to affiliate with one or more chapters, or not affiliate with any chapters at all. Affiliation is encouraged as it allows local contact among members and provides chapter voting rights to members affiliated with particular chapters. Join here!
