Babbage traced Chambers Creek into Lake Eyre, and was thus the first discoverer of this lake, which he called Lake Gregory.
He found a range which he called Hermit Range, but from its crest discerned no sign of Lake Torrens, thus settling a certain limit to its extension to the north.

He made further explorations to the west of Lake Gregory, now Lake Eyre, and found some hot springs.

Meanwhile, during the time he was making these researches, the Government had, in a very high-handed manner, appointed Warburton to supersede him.

Warburton started out to find Babbage, taking Charles Gregory as his second.
Failing to find him at the Elizabeth, he followed and overtook him at the newly-discovered Lake Gregory.

Warburton made a few discoveries while seeking for Babbage, amongst them the Douglas, a creek which was afterwards of great assistance to Stuart, and the Davenport Range; and he also came upon some fair pastoral country.
Babbage's surveys and explorations had done much to clear up the mystery and confusion that had hitherto obscured the geography of the salt lake region.
