Dr Kelsey Lowe (from UQ’s School of Social Science) walking a grid pattern with a ground penetrating radar. This tool is measuring the magnetic signature at a stone arrangement on Mithaka Country in 2021. Changes in the magnetic signature of the soil can reveal any changes beneath the soil such as evidence of a hearth or fireplace, if the soil is different to the surface or if there is anything buried beneath such as a grave site. “Soil magnetic studies combined with experimental burning show that magnetically enhanced sediments in Gledswood Shelter 1 are the result of anthropogenic burning of hearth fires, which burn hotter and for a longer time than natural wild fires”(Lowe, et al, 2016). Using Ground penetrating radars provide an indication to researchers of a good place to start an investigation/excavation pit.
