Souris River Capture

At some point in time, headward erosion by a stream running through the Tiger Hills reached a point where the Souris River was captured and sent northward to the Assiniboine River.  The capture occurred at "the elbow" region, just east of highway 10.  Previous to that event the Souris River continued in the Pembina Valley.  Below are some pdf files of research done on the area and southwest Manitoba in general.

General photos of southwest Manitoba: spring and summer 2016

Below are a few photos taken on 22 May 2016 showing some of the elbow region and the Souris/Pembina valley close-up.  On this particular day a local thunderstorm had just passed nearby and to the North.  One could hear both the storm's distant thunder and the Souris river running over the rocks of the river bed.
