Ice dunes are produced by ice washing ashore, snowfall, and the gradual freezing of wave spray that accumulates on to the shore. They form when the air temperature is below freezing and the water temperature is near freezing. Ice dunes are commonly at least 6 feet (1.8 m) tall, but the dune’s size depends on the beach and the weather. The “storminess” of the water and the topography of the beach all can effect the size of the dunes. The dunes will also stop forming if the body of the water they border freezes over, which often happens on Lake Erie. Ice dunes will usually break up in the early stages of spring thaw. – source, Wikipedia
These photos were taken at Wildwood Park in Cleveland. We usually head here every winter for photos but I don’t remember seeing ice dunes this size in this spot before. At Presque Isle State Park in Pennsylvania even larger ice dunes form. Looks like it would be fun to walk on them huh? It is extremely dangerous as they are often hollow. Despite it’s appearance, I assume that the ice must not be very thick at this spot because we usually see ice fishermen and there were none.
Euclid Creek flows into Lake Erie and it was frozen solid. These dogs looked very happy!
