An old picture from a long time ago, but they were doing a study on the snakes when I was their. They were keeping males separate from females for a few days then introducing them to see what their behavior was like. So they didn't use the same males they marked them like so.
Picture from last week. 8 Kilometers from the den and this female was making her way back to the dens before winter comes.
