WebJan 16, 2024 · Multiyear ice tends to be thick, sturdy and reflective. Young, thin ice is darker and absorbs more energy from the sun. Rafted ice happens when the wind pushes thin sheets of ice on top of each other. Leads are large cracks that open between ice floes. When the ice pushes back together, it can form pressure ridges — small mountain chains of ice. gas stations in brady tx
