carried out numerous expeditions partly financed by the government. In 1897 from a base at Nullagine, Hann explored the east Pilbara, and noticed creeks in the area flowed inland. He followed them expecting to find a large fresh water lake, but to his disappointment the lake turned out to be salt. Consequently, he named the feature Lake Disappointment. Hann's explorations covered a great deal of the state while searching for mineral wealth and pastoral prospects. From 1903 he based himself in a tent about east of Laverton. His expeditions from the locality (shown as "Hann's Camp" on modern maps), extended as far as the Petermann Ranges in central Australia and Oodnadatta in South Australia. He left a legacy having named over 500 geographical features, including the rivers Rudall, Isdell, Charnley and Phillips (now the Hann); lakes Yeo and Rason; and ranges Mackay, Sir Frederick Bedford and McFadden Range. In 1909 Hann shocked people in Perth by a report saying that he had an encounter with Wongi warriors north of Laverton, and regretted not shooting one as he wanted to get a skull for Fred Brockman to send to London. When outrage followed, he retracted his statement and later the authorities stated that he was just exaggerating, but was also no longer in the employ of the Surveyor General. Brockman subsequently wrote that Hann did get him a skull but it was from a person who had died four years earlier. Later life In 1918 Hann was injured in an accident which left him on crutches after which he retired to Perth, where he died in 1921. He was buried in the Karrakatta cemetery in Perth, and in October 1986 a memorial plaque was added to the gravesite. Legacy Frank Hann National Park, Hann River and Mount Hann () are named in his honour.
