What is Olia chain?
{{coord|25|29|S|130|10|E|type:mountain_region:AU-NT|display=title}} The '''Olia Chain''' (or '''The Olias''') is a [[mountain range]] in the southwest of the [[Northern Territory]], [[Australia]]. It forms the southeastern end of the [[Petermann Ranges]], and connects these ranges with the [[Musgrave Ranges]] further south. The Olia Chain consists of scattered outcrops of rocky hills, separated and surrounded by [[Sand dune|sandy]] [[plains]]. It extends from Katamala Cone (828&nbsp;m) at its northern end to [[Mantarur]] (including Butler's Dome, 1102&nbsp;m) in the south. The centre of the chain is dominated by Stevenson Peak (1025&nbsp;m). A few kilometres northeast of this peak is a [[Pitjantjatjara]] [[outstation]], called Pirrulpakalarintja. The Olia Chain mostly consist of flat-topped ridges composed of [[sandstone]], [[slate]], [[quartzite]], and [[limestone]] rock beds. {{geo-stub}} [[Category:Mountain ranges of Australia]] [[Category:Mountains of the Northern Territory]]
