The Magpie river then leaves Esnagi Lake at the south end where the Canadian Pacific Railway transcontinental mainline crosses.

It continues south, passes over the Jean Falls, and takes in the left tributary Peckerwood Creek at an elevation of 339 metres (1,112 ft).

The Soderston Creek enters from the right, and the river passes over the Toolong Rapids, where it once again heads south.

The river takes in the right tributary Catfish Creek, and reaches Wawa, where it is crossed by the Algoma Central Railway branch line to Michipicoten Harbour and Highway 17.

To protect the natural landmark, the Innu Council of Ekuanitshit and the Minganie Regional County Municipality declared the Mutuhekau Shipu a legal person in 2021.
