Nathaniel Buchanan

In 1850 the brothers went to the California Gold Rush, but returned to Australia after a short stay to find that their station had been mismanaged and lost in their absence.

In 1859 Buchanan explored new country with William Landsborough, principally on the tributaries of the Fitzroy River, Queensland, when both suffered many privations and were found just in time by a rescue party.

In October 1877, with a companion, Sam Croker, Buchanan began to investigate the country from the known regions round the Rankine to the overland telegraph line, around 800 kilometres (500 mi) away.

About two years later, with another man and an aboriginal boy, he started with camels and equipment provided by the South Australian government to find a stock route from northern Queensland.

Returning to Flora Creek he prepared a report for the South Australian government which added much to the knowledge of the country, though Buchanan had failed in his main object.
