Burke split the expedition at Menindee and the lead party reached Cooper Creek on 11 November 1860 where they formed a depot. The remaining men were expected to follow up from Menindee and so after a break, Burke decided to make a dash to the Gulf of Carpentaria. Burke split the party again and left on 16 December 1860, placing William Brahe in charge of the depot on Cooper Creek. Burke, Wills, King and Charley Gray reached the mangroves on the estuary of the Flinders River, near where the town of Normanton now stands, on 9 February 1861. Flooding rains and swamps meant they never saw open ocean.
