I photographed this image in the winter of 2004 near Gatlinburg in Tennessee.  I found this composition along a mountain stream early one morning when it was very cold.  Intricate patterns were produced as the water and trapped air moved beneath the ice.  I used the Mamiya RZ67 with the Mamiya Sekor 140mm Macro lens, tripod mounted and mirror-up, to expose this image on Kodak Portra 400VC negative film.
