. It is in Sullivan Bay, part of a channel that separates Bartolomé from nearby Santiago Island. The rock is part of a now largely eroded volcanic dike that once connected the two islands.

Tourists dive in scenic reefs offshore of the rock.

This was originally a part of the volcanic mass that now occurs behind it on the island. If subsequently marine erosion separated it from the island it would be a stack. After that volcanic boulders and a sand beach appear to have connected it once again to the mainland, to which it is very close. If so it would be a tombolo. The other scenario would place it, as a proto-stack if never completely severed from the island at its base (now covered by boulders and sand). {{cite news , url = https://vancouversun.com/travel/international-travel/galapagos-evolved-land-based-pikaia-lodge-embraces-green-living/ , title = Galapagos Evolved: Land-based Pikaia Lodge embraces green living , work =
