@llundgren, @mackenzie-white: Wow, you guys are right – the Chinle Formation is stunning! I like the idea of possibly doing a mini conference with the Southwest Paleontological Society or connecting with a regional GSA section meeting. Looks like the Chinle Formation is technically in the Rocky Mountain Section of GSA, while the rest of Arizona is in the Cordilleran Section. (Weird that they split a state between sections!)
