Dennistoun's claim to have reached the top was disputed by Donald Sutherland, who had claimed that Mitre Peak could not be climbed. In 1914, Dennistoun's handkerchief was found in a small cairn on the top of the peak by Jack Murrell (1886–1918) and Edger Williams (1891–1983) when they completed the second ascent of the peak. When J.H. Christie and G. Raymond completed the third ascent in 1941 they found remains of the handkerchief, as well as two halfpennies left by Murrell and Williams.
