Llao Rock is a prominent rock pillar on the north rim of Crater Lake in Crater Lake National Park, Oregon, rising 1,870 feet above the lake in only 0.28 mile and creating striking relief above the caldera wall. Named for Llao, a Native American god, its place name was officially adopted in 1897 by the United States Board on Geographic Names. The surrounding Llao Rock Research Natural Area is also ecologically sensitive and has been closed to summer hiking since 2013, when snow cover is less than one continuous foot, to protect rare and fragile plant species. In the region’s harsh subalpine climate, it remains a notable geological landmark.
