Geosonnet 62



Charles Sturt believed there was an inland sea
Where westward winding rivers could discharge
This destination proved illusory
And yet his name’s on desert, gorge, litharge.
Among the rocky features labelled Sturt
An ancient glaciation bears his name
Geologists today wish to assert
Exactly when this global ice age came.
But Glac’ers oft erode what lies below
Entire sections thus are hard to find.
A dozen million years post-Inslay show
The isotope and ice are not entwined.
Seven one seven million years from then
Sturt chased mirage hypotheses again.
