At 1142pm AKST (1241pm AKDT) Monday the tripod on the Tanana River at Nenana was still standing (as seen in this photo) making this now the latest break-up of the winter ice of record (since 1917). The previous record was 1141 AKST May 20, 1964. The tripod fell three hours later, at 341pm AKDT as the ice began running.
