When I see this phenomenon where I’m now living, I’m reminded of an ice floe stampede one Sunday afternoon on the Susquehanna River back in the winter of ‘71. For two hours or so after an ice jam upstream had been dynamited, the river was a racetrack of large jagged white wedges three or four feet thick crashing down the riverway. Viewing it was terrifying, mystifying and unforgettable. Slabs of the ice that had been thrust into shrubs along the riverbanks remained visible until nearly May.
