The cows, after meals, wander up under the tall fir trees during snowy weather for protection. When the temperatures drop and the cold nights freeze the ground solid, the herd heads on trails in the snow that they had established weeks ago.
Single file on these trails are the safest for the cows and the calves that they are carrying. One slip on the hard crusted snow could break a hoof, fracture an ankle or displace a hip.
The herd has been able to stay upright and healthy through this cold stretch of winter.
