Two Main Mountain Ranges in South Australia

South Australia's principal ranges:

1. Mount Lofty Ranges — Southern SA, ~250 km N–S. Highest: Mount Lofty (727 m). Includes Adelaide Hills.
2. Flinders Ranges — Northern SA, ~450 km N–S. Highest: Mount St Mary (1,170 m). Dramatic folded ridges, Wilpena Pound.

The Lofties are ancient, eroded, Mediterranean-climate; the Flinders are younger, arid, geologically spectacular.
