The expedition was the culmination of several varying investigations over the previous decade: Madigan's first aerial reconnaissance in 1929, Colson's crossing (practically along the 26th parallel) in 1936, and a journey by truck around the northern end of the desert in 1937. This pioneering scientific expedition, of nine men and seventeen camels, left Andado in early June and reached Marree on 8 August, after a journey of 800 miles in a little over ten weeks.
