Another team of surveyors visited the area in 1926, led by Donald Mackay and Herbet Basedow. On 1 July, they climbed a hill that Basedow identified as both Mount Unapproachable and Mount Harris. He found them to be the same mountain after comparing his own observations with those of Giles and Tietkens. Basedow decided that this hill was the Mount Unapproachable that Giles had described, and that Tietkens had mistakenly renamed it Mount Harris. But, on modern maps, Mount Harris and Mount Carruthers are the names given to two peaks in the Bloods Range.
