Island Rebound (September 6, 2007)

Island Rebound
Resembling Pac-Man, Canada’s Akimiski Island—located in James Bay, the southern tip of Hudson Bay—is a reminder of the power of glaciers. During the last glacial period, a massive ice sheet covered Akimiski. When the climate warmed, the ice sheet retreated and as the weight of the ice was removed, the island “rebounded,” just like a mattress that springs back up after a person gets out of bed. Waves created a series of “bathtub rings” around the island’s coastline as Akimiski slowly rose and sea level changed.
