Fossilized Footprints - White Sands National Park

For 80 years, only a small collection of fossilized footprints were known to exist at White Sands. However, in 2006, a group of scientists noticed dark spots dotting the expanse of the lakebed that appeared to be footprints. Their curiosities lead them to dig up these dark spots in 2009. This led to the discovery of both Harlan’s ground sloth and human footprints.
