Human History Recorded In Mud

When you step into mud, it kind of slurps up between your toes. What if someone found your mud-slurping footprint 15,000 years from now?

Scientists have uncovered 15,000 year old fossil human footprints, with incredible, mud-slurping detail. What do they tell us about the people that lived there? 

Follow The Foliage!

The fall is a beautiful time of year here on the East Coast, and in North Carolina, we have a resident expert who has long been the go-to scientist for local leaf-peepers: Dr. Howard Neufeld, professor of biological sciences at Appalachian State University. He is learning how and why trees turn color in the fall, as well as why some turn red, while others turn yellow. 

Alaskan Glaciers Tell A Story Of Deep Time

Rock, once a seafloor of mud, sand, and pebbles, towers into the sky, only to erode away, becoming a new and different seafloor, layered like pages in a book.

Appalachian State University's Dr. Ellen Cowan reads these pages, most recently off the coast of Alaska. They tell the full story of geological changes on the continent, as written by glaciers over millions of years.
