The Bruce Museum's exhibition, Double Exposure: Aerial Photographs of Glaciers Then and Now, documents one aspect of the warming climate through fourteen pairs of panoramas of glaciers once grand but now receding, as shown in large-format, fine-art photographs of mountains and glaciers from Alaska and Switzerland.

Museum hours are: Tuesday through Saturday 10 a.m. to 5 p.m., Sunday 1 p.m. to 5 p.m., and closed Mondays and major holidays.
