Our international membership includes scientists, educators, and authors who are leading the study of natural arches as well as hobbyists who simply enjoy visiting and learning about them.

Our newsletter, SPAN, provides news, information, and special interest articles on both the scientific and non-scientific study of natural arches, including their discovery, history, measurement, location, and general appreciation.

Any person with an enthusiastic desire to visit, study, photograph, or write about natural arches, and who supports the preservation of these features, may become a member.
