"Love them".

"So good to see them back on location!"

Bartley also posted another photo on his Instagram account this week of his costar Katee Sackhoff, who plays "Vic" Moretti. The actress is seen staring at the camera with her very expressive eyes and her hair down. The actor simply added the caption "Gorgeousness" to describe his costar.

The cast and crew of Longmire are currently underway on the third episode of season 4. Netflix picked up the Western drama for a 10-episode fourth season after A&E surprisingly cancelled it. The show had been A&E's top rated scripted series before cancellation but its ratings in the 18-49 demographic were apparently too low for the network to keep it around.
