Thanks. Here’s what I found as far as locations:
The series was primarily shot in New Mexico, spanning locations like Las Vegas, Santa Fe, Eagle Nest, and Red River. Multiple seasons of the show shot interior scenes at Garson Studios at Santa Fe’s University of Art and Design. For the third season of the show, a majority of the exterior scenes were shot in nearby locations in Santa Fe.
Beautiful country up there. If you don’t mind altitude that is.
Looked up film locations for Yellowstone after remembering seeing the Utah Film Commission mentioned in the credits. Most of the first 3 season were filmed in the Park City area with the ranch being near Darby Montana. Since they weren’t going to get enough tax credit/rebates/incentives for the new season the production moved to mostly Montana for season 4.
