2022: The West MacDonnell Ranges, as photographed with new Mavic 2 Pro drone from Honeymoon Gap. Strike ridges of Heavitree Quartzite (~800Ma) delineate the east-west orientation of the range. They are overlain by the madly-folded formations of the Bitter Springs Group. The ranges were uplifted as part of the Alice Springs Orogeny (500Ma to 300Ma), which was unusual in that it occurred mid-continent as opposed to on a plate boundary.
