Southern rock of Marotiri

Marotiri is a group of four uninhabited volcanic rocks protruding from the sea (and several submerged rocks), forming the southeastern end of the Austral Islands of French Polynesia. Marotiri is also known as Bass Rocks (Îlots de Bass in French),[2] maybe according to the name of the European explorer George Bass. Marotiri is very isolated,[3] located about 1,167 km (725 mi) west-south-westward of Pitcairn Island.[4] The closest island is Rapa Iti, 75 km farther northwest, but separated from it by an ocean depth of more than 1,500 meters.[5] The rocks are part of the municipality of Rapa.

The climate is wet temperate. The rocks are almost devoid of vegetation.[4] They are important as a seabird rookery. Fish abound in the adjacent waters. The rocks emerge from a submarine platform 100 meters deep and 5 km in diameter. They lie at a distance between 1.5 and 3 km from one another. The total land area is 43,100 m², which is broken down as follows by the individual rocks:

Rock Area
(m²)
Northern Rock 5,800
Central Rock 1,800
Southern Rock 22,400
Western Rock 13,100
Marotiri 43,100

The southern rock is the largest, with a height of 113 meters at its highest point.
