Canada's Prairie Pothole Region
Alyssa Vibert — July 1, 2021The Canadian Prairie Pothole Region (PPR) encompasses 467,000km² of wetland and grassland area stretching from Alberta’s Rocky Mountain foothills to Manitoba’s Red River Valley. The appearance of these ‘pothole’ structured wetlands, were formed by the movement of glaciers across North America, where the ice melted into the pools that are now the potholes wetlands we have today. The formation of the pothole region took tens of thousands of years during the Wisconsin glaciation period.
