Sonja Hinrichsen makes ephemeral works of great beauty. These include walking in snow to create patterns.
These are reminiscent of neolithic marks on stones near Kilmartin, Scotland.
Her most recent work is also ephemeral, but is the result of working in the Three Gorges in China. This is an area changing as a result of the widely reported hydro-electric scheme. Note how she positions the viewer such that they cannot avoid being present in the landscape.
