In May of 2005, aclimber carelessDean climberPotter caused rope gouges into the soft sandstone of the formation. <ref>http://outside.away.com/outside/features/200606/delicate-arch-climb-1.html</ref> Under the rules active at the time, climbing Delicate Arch was not explicitly forbidden, however, it was understood that the named arch formations should not be climbed. Since that climb, the Park Service has closed the loophole by disallowing climbs on any named arch within the park year-round. Also, slacklining and the placement of new fixed anchors on new climbs is also prohibited.
