You can find hexagonally-patterned rocks in Petoskey, MI, that are actually fossilized corallites. Petoskey stones were formed during a prehistoric ice age that scattered them to the shores of Lake Michigan. The dark spots were the coral’s mouths, and the tiny lines were tentacles that reached out for food. Source Source 2 Source 3


The bitter cold and windy winter weather of the midwestern US has transformed frozen sand on the shore of Lake Michigan in St. Joseph, MI into a sea of tiny wind-sculpted towers. The Department of Awesome Natural Phenomena is currently debating whether they look more like features from an alien landscape or part of a miniature national park. Photographer Joshua Nowicki happened upon this incredible sight, and captured these marvelous photos of what turned out to be a short-lived phenomenon. As soon as the sun came out, its warmth caused the wee sand castles to disintegrate.

Last Friday afternoon, photographer Nick Ulivieri was on an aerial photoshoot for a client when the helicopter pilot took a long turn out over Lake Michigan so he could better capture the shadow of the Hancock Center. After reviewing his photos later he quickly realized the exaggerated autumn shadow of the skyline looked fantastic when he flipped the photo.
