Perhaps one of the most recognised landmarks of Lake Eyre, by name at least , is the Warburton Groove.
It’s where the Warburton Creek runs into the lake at the very northern, or top end.
Over time when it floods, which isn’t too often, the waters have cut a channel in the lake bed.
I imagine it sounded a better option to our explorer forefathers than calling it the Warburton Ditch
