While doing some work on their property in Central Texas, a family discovered more than a dozen diamondback rattlesnakes in a den.

Chrissy Fox Fink said she lives on 13 acres of land in Niederwald. When they bought the property 16 years ago, the owner stored landscaping supplies, including huge piles of limestone, in the area. In the past few weeks, they offered some of it to a neighbor working on his own landscaping.

When he started moving the rocks, the venomous snakes were disturbed, too. Fink said he shot the snakes with his pellet gun while he stayed on the tractor. She snapped a picture of more than a dozen dead snakes on a rock.

“We stopped because of dark but there are for sure more in there,” Fink said.

Snakes often make dens on large rock formations. Being off the ground can protect them from flooding, and the rocks can help keep them warm.
