Anchor ice has been wreaking havoc on some Jackson residents and businesses this week. Also called frazil ice, it’s a rare phenomenon in which the river freezes from the bed up, so flowing water spills out from the sides of the waterway.

Teton County Emergency Management Coordinator Rich Ochs says Jackson’s Flat Creek is one of the few places in the country with prime conditions for anchor ice to form, winter after winter. Ochs says this year has been particularly tough because of the constant freezing temperatures.
