'''Ball's Pyramid''' is an uninhabited [[islet]] in the [[Pacific Ocean]] located {{convert|20.|km}} southeast of [[Lord Howe Island]], between [[Australia]] and [[New Zealand]]. The steep rocky [[basalt]] outcrop is the eroded [[volcanic plug|plug]] of a [[shield volcano]] and [[caldera]] that formed 6.4{{nbsp}}million years ago.<ref name="bpe"/><ref>{{Cite web |last=Woodroffe |first=Colin |title=Balls Pyramid and the efficacy of marine abrasion |url=https://serc.carleton.edu/vignettes/collection/35376.html |access-date=2023-06-28 |website=Vignettes: Key Concepts in Geomorphology |publisher=Carleton College |language=en}}</ref> It is {{convert|572|m}} high, while measuring {{convert|1100.|m}} in length and only {{convert|300.|m}} across, making it the tallest volcanic [[stack (geology)|stack]] in the world.<ref>{{cite web|url=http://www.lordhoweisland.info/conservation/geo.htm|title=Geography and Geology|archiveurl=https://web.archive.org/web/20140912073751/http://www.lordhoweisland.info/conservation/geo.htm|archivedate=12 September 2014|work=Lord Howe Island Tourism Association|accessdate=2009-04-20}}</ref>
