IIRC, although Longmire is ‘set’ in Wyoming, it was actually filmed in New Mexico.
Good series. I did think the finale was a bit stretched.
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.
