Combined with our results of dune and spit formation, the existing data clearly imply active sediment supply from the Flinders Ranges at ~6e7 ka leading towards peak mid Holocene lake levels of ~3e4 m AHD at Lake Frome with the formation of the spit shortly
after 5 ka. This scenario is in general agreement with other proxy records from around the Flinders Ranges documenting wet conditions between ~7 and 3 ka (Gliganic et al., 2014; McCarthy and Head, 2001; Quigley et al., 2010).
