You can join online by credit card (credit cards are processed by Stripe) using the form below. Alternatively, you can join by mail by sending a check to the address below. Please complete and mail-in our membership form.

New members are eligible for a 20% discount on a 1-year subscription to the World Arch Database (not owned or controlled by NABS), a searchable database of the arches of the world with photos. This discount is available in the Members-Only section of our website.

NOTE 1: The Natural Arch and Bridge Society provides an annual membership roster to its members to facilitate the sharing of arch information and trip planning, and this has been a popular member benefit. If you do NOT want your contact information included in this roster, please indicate “no roster” in the special instructions box.

NOTE 2: If you don’t want a printed color copy of SPAN mailed to you, you can request a digital-only (PDF) copy instead. Just put “digital only” in the special instructions box. If you decide later you want to change to or from digital-only, you can just email us.
