Today, the site of Voorhies's discovery is called Ashfall Fossil Beds State Park, and it has a stylish new visitors' center and museum, with thoughtful displays on the geology of Nebraska and the history of the fossil beds.
The Ashfall Fossil Beds of Antelope County in northeastern Nebraska are rare fossil site types called lagerstätten that, due to extraordinary local conditions, capture a moment in time ecological "snapshot" in a range of well-preserved fossilized organisms. Ash from a Yellowstone hotspot eruption 10-12 million years ago created these fossilized bone beds.
