A raft of ancient glacial dropstones are set adrift on North Terrace in front of the South Australian Museum.
Carved and polished by the glaciers that ice rafted them to what is now the dry interior of South Australia, the dropstones contain the liquid memory of a remarkable 120 million year old history of water and continental drift in SA.
In Adrift, the desert’s dropstones, once suspended in frozen water on their original journey to the inland sea, are now resuspended, afloat and adrift in shallow waters on Adelaide’s North Terrace.
49 smooth dense stones approximately 650mm in diameter are set in an open grid on a partially submerged 7 metre square raft. Underwater jets gently buffet the raft around a 13 metre square pool. The raft aerates the water above it, creating an energetic zone around the stones in contrast to the calm water of the pool. The different qualities of water reference the meeting of glaciers with the warmer waters of the inland sea, whilst the defined square of aeration ‘holds’ the stones reminiscent of the glacier that once ‘held’ them millions of years ago.
Evocative of ‘journey’ in all its poetic guises, the raft beckons the mind to travel in time and place from the urban present.
