List of longest natural arches

From Wikipedia, the free encyclopedia

This list of longest natural arches ranks the world's natural arches by the length of their span as reported by the Natural Arch and Bridge Society.

As a disclaimer, the NABS states that the information in this list, and therefore the rankings, are subject to change due to a variety of reasons that may include updated measurements, changes in span due to natural forces, and the discovery of previously unknown arches. ^[1]

As of 2008, the ten largest natural arches are also the only arches with a span known to exceed 200 feet.
