This photo taken on the 1932 Endeavour Expedition to Central Australia, on the northern side of the Rawlinson Range, shortly after leaving Circus Rockhole. It is not known whether Lasseter marked the tree on his outward journey or return from Lake Christopher. Therefore the usual convention is assumed, that is the tree was marked on the outward journey, thus placing Lasseter at Lake Christopher on 2/12/30 or 3/12/30.
