I am sure that I know the general area of 2 dens. Big rocky cliffs across the road and on the other side of the river. I kill a lot of the little young ones on the road below that. You know those foot long one button snakes aren't far from the den. I kill them on the road around the sheep sign. The other is around Big Rock which is over a mile up the hill behind the house. A picture of my wife by Big Rock. You see less than half the rock in this picture. Lots of big broken rocks on the other side of it. She is standing by a spring fed water trough. Rocks and water. The snakes really like to have both.
