🌙✨ Tonight's the night! We're heading into the Fossil Butte Member for a night dig in the legendary 18-inch layer — one of the richest fossil fish beds on Earth, hiding 52-million-year-old secrets just beneath the surface.
Headlamps on, tools ready, and our guests are buzzing with excitement. You never know what's waiting in this layer — perfectly preserved Knightia, maybe even something rarer. 🐟🔍
Follow along as we uncover a piece of ancient Wyoming, one layer at a time.
