My favorite memory of Mongolia is the first day we found Ukhaa Tolgod in 1993. We found nearly 100 dinosaurs, mammals, and lizards that day. It didn't look like much from a distance, only a few red brown hills. But we practically tripped over skeletons of Protoceratops, lizards, and mammals as we got out of the car. Within an hour, we knew we had found the "field of dreams" of our collective lifetimes.
It's hard to describe the feeling of elation and the shock of disbelief that such a discovery brings.
