Landowner Ann Hoff discovered this site several years ago. The locality consisted of a juvenile duckbill dinosaur skeleton spread out over a large area. The bones were preserved in an iron carbonate concretion, but were beautifully preserved. While this site was not as complete as several other skeletons collected in 2008, it was important because it was from a juvenile individual.
