'''Redonda Rock'''{{efn|The name sometimes also appears as '''Redondo Rock'''.{{sfnp|McEwen|1988|p=235}}<ref>{{citation |last=Kitchin |first=Thomas |title=Kitchin's General Atlas... |publisher=Laurie & Whittle |location=London |date=1797 |contribution=[[:File:1795 D'Anville Wall Map of South America - Geographicus - SouthAmerica-laruiewhittle-1794.jpg|South America]] }}.</ref>}} ({{lang-es|Roca Redonda}}, "Round Rock") is a flat-topped, steep-sided [[Earth:Islet|islet]] located roughly {{Convert|25|km|mi|abbr=on}} northwest of the island of Isabela in Ecuador's [[Earth:Galápagos Islands|Galápagos Islands]]. Redonda measures {{Convert|100|m|ft|abbr=on}} long and {{Convert|50|m|ft|abbr=on}} wide with a maximum elevation of {{Convert|67|m|ft|abbr=on}}.<ref name="SI">{{cite gvp|vnum=353807|name=Roca Redonda |access-date=2016-09-16}}</ref> Its isolation and inaccessibility coupled with its rocky cliffs riddled with crevices and crossed by ledges has made Redonda a haven for nesting seabirds.<ref>{{cite book|title=The Galápagos: Exploring Darwin's Tapestry|last=Hess|first=John|page=42|year=2009|publisher=University of Missouri Press|isbn=978-0-8262-1837-7}}</ref>

This small volcanic island is the remains of a large [[Earth:Shield volcano|shield volcano]] that has vastly eroded away below sea level. Potassium–argon dating of Redonda indicates that the islet is at least 53,000 years old.<ref name="SI"/> However, it remains unknown when the last eruption occurred from the shield volcano. Several shallow submarine fumaroles exist around the island and may indicate that the volcano is still active.<ref>{{cite web |url=https://www.researchgate.net/publication/225670475 |title=The emergence of a Galápagos shield volcano, Roca Redonda |publisher=[[Physics:Springer-Verlag|Springer-Verlag]] |access-date=1 October 2023}}</ref>
