The landscape of the upper Todd River catchment is complex, reflecting a vigorous but staged evolution since possibly the early Tertiary. At that time, bedrock and sediments in a prior valley were subjected to intense weathering which resulted in the development of a deep mantle of saprolite.
The valley floor sediments were silicified then dissected, and detrital laterites later developed in drainage floor environments. Rapidly aggrading piedmont deposits flanling adjacent uplands subsequently buried this prior valley and culminated in the development of an extensive palaeoplain which is now drained by 16 Mile Creek. The Todd River drainage system has dissected this palaeoplain to form the present catchment, partly exhuming the landforms of the early Tertiary valley floor in the process.,
