Shear Walls on the Hay River

Shear wall left behind after an ice jam release event on the Hay River, NWT (Canada), May 6, 2008

Shear walls are left behind when an ice jam releases.  The shear line, between the moving and stationary ice, is near vertical and these particular shear walls were several metres high.  Although breakup happens in late April or early May, this remnant ice along the banks often does not melt away until early June.
