“Deep weathering” is a geologic process that takes millions of years of seasonal wetting and drying of certain rocks to produce high levels of iron-oxide. The result is a rich, red soil, perfect for crops like sugar cane and sweet potatoes. Evidence of deep weathering is in the fertile soils of Bundaberg, a regional town in Australia with a violent colonial past, yet a key part of the nation’s food production and hub for seasonal migrant workers. The region is a hive of mobility, millennia in the making, that epitomises contemporary debates on housing, migrant labour, global supply chains, and ecological destruction. This visual essay presents a series of creative experiments of making jam at roadside rest areas. Using a hiking stove, third-grade fruit the farm workers bring home, locally produced sugar, a hint of soil, the process is a creative conversation across geologic and human mobilities in the region.
