About Us
The Natural Arch and Bridge Society (NABS) is an all-volunteer non-profit organization promoting the study, appreciation, and preservation of natural arches and bridges. You can contact us at info@naturalarches.org and you can join online below.
NABS was formed in 1988 as a tax-exempt 501(c)(3) educational organization to support the interests of both amateur arch enthusiasts and serious researchers of natural arches and bridges alike. 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. See newspaper article about the late former NABS President Larry Beck.
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.
Membership entitles you not only to receive our quarterly newsletter SPAN, but also to participate in our field trips, meetings, presentations, and all other NABS activities. Members also have access to back issues of SPAN in PDF format.
