Pinnacle Rock (Galápagos)

Pinnacle Rock, is a celebrated volcanic plug on Bartolomé Island, one of Ecuador's Galápagos Islands.[1][2] It is 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.

The rock is the site of ramalima lichen.[3]

Travel writers describe the rock as one of the most spectacular views in the Islands.[1][4][5][6][7] A colony of penguins makes its home at the foot of the rock.[8] Tourists dive in scenic reefs offshore of the rock.

One morning, we woke up at 5:30 a.m. for a hike on Bartolomé Island, where we climbed 326 steps to take in one of the most iconic formations in the Galápagos—Pinnacle Rock.

At the northern end of Sullivan Bay, Pinnacle Rock rises to a sharp pointed prominence (Fig 12). 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).

There are few better than those glimpsed from the top of Bartolome, a spot that looks out on one of the most famous and photographed panoramas in the Galapagos. Gazing east, there the pockmarked remains of several splatter cones. To the west, there are remains of an eroded tuff cone known as Pinnacle Rock. CS1 maint: discouraged parameter (link)
