How ice forms on the big lake

In her blog entry on Monday, Barbara Spring — who lives along the big lake in Grand Haven, and is the author of environmental books as well as poetry — took an excerpt from one of her books that explained how ice forms.
"The first crystals of ice begin where water meets the shore," Spring wrote. "Ice crystals must have something solid to cling to in order to form. This is why ice does not form out in the middle of lakes first, but begins to build along the shoreline.
"When the temperature plummets and the water takes on a steely sheen, ice gains a toehold on the shore. Crystals of ice build into a formation known as an ice foot. The ice foot builds out into the lake and eventually becomes a strong seawall that will protect sandy beaches from erosion during fierce winter storms."
