Our engorged rivers are reshaping the Canadian landscape to the extreme this year. Water, in its eternal compulsion to conform to gravity, etches its slow-hewn language through valleys and onto flatlands. Now a new sinkhole has opened up along the Souris River in an undisclosed location near the town of Souris, Manitoba.
Similar in features to the Dauphin sinkhole, it appears calling either of these a sinkhole is a misnomer. Landslide appears to be the official explanation of the phenomena at both sites. The adjacent rivers and their abundant flows this year have eaten away enough of the banks for masses of earth to slide into the valleys. At the Dauphin site, the Vermillion River takes a sharp deep turn just below the landslide. At the Souris site, the valley wall appears to have collapsed and slid toward the river.
