We are in the process of deciding whether or not to return to walking in the northern Flinders Ranges in 2021. The two options currently on the table are either walking in the Gammon Ranges with Suzanne’s walking friends under the umbrella of the ARPA Bushwalkers; or doing another camel trek, this time from Blinman to Lake Frome.
I have returned to looking through the archival photos made on the earlier 14 day camel trek in the northern Flinders Ranges we did in 2018. This picture is from the morning of day 2 just before we started the days walk:
Day 2 was a short walk and it enabled us to spend the afternoon exploring the ruins of Yudnamutana mine and the smelter site. Yudanamutana also refers to the copper field of this name.
This mine was worked intermittently for copper from around 1862; work was abandoned in 1867, then picked up by the Flinders Copper Mining Company and worked between 1914 and 1918.
At the end of the first day of walking we camped at a wonderful campsite close to Blue Mine Gap on the north western edge of the Gammon Ranges. We were walking in there of Sir Douglas Mawson’s 1906 explorations into the geology of the northern Flinders Ranges. In the 1920s and 1930s Mawson amongst others concentrated his research and fieldwork around the mineralization the northern Flinders Ranges, eruptions of the pre-Cambrian glaciation throughout the Flinders Ranges, the Cambrian strata of the Flinders Range, and the identification of uranium at Mt Painter Inlier, which is about 100 kilometres north east of Leigh Creek and south of the Mawson Plateau. South Australia is one of the world’s focal points for the study of the late pre-Cambrian era and glaciation.
After lunch on the first day we crossed a creek bed. The camels were playing up a bit, and this gave me 5-10 minutes or so to do some photography in and around the creek bed. Surprisingly, the light was still soft due to the continuing cloud cover, and the malaleucas in the creek made a welcome change to the bareness and environmental degradation of the stony hills with the loss of endangered plants and animals from the history of extensive pastoralism since the European occupation of the land.

We had left the Umberatana Station track to walk in, and along, the Blue Mine Creek on the way to the campsite for the night. It was dawning on me that there was a history of extensive mining in the region for copper in the 19th century, and that the systematic regional mapping of the northern Flinders Ranges after 1945 centred around finding coal, petroleum and uranium. Mining was just as crucial as pastoralism in terms of land use. Increasingly it is now eco-tourism that provides the income and employment in the region. Continue reading →
