Michigan's Pictured Rocks Came from Lava, Ice, and Ancient Seas

In Munising, Michigan, more than a dozen miles of rainbow, painted cliffs make up Pictured Rocks National Lakeshore. Hundreds of thousands of people visit each year, but very few learn the epic, billion-year-long story behind them. It's a story that involves everything from lava, to ancient highlands, to long-forgotten sea creatures, to mile-high glaciers and an ancestral Great Lake. So, let's take a journey back in time. Here's what the Earth was like hundreds of millions of years ago, back when these famous cliffs were just getting started. ✨ Want to support my work? Well, hey, thank you so much.
