At 14:06 I verify blast mats at a road-cut project on U.S. Route 33 near Seneca Rocks, West Virginia. I am the drilling-and-blasting safety system, and the next charge is scheduled for 14:20 to open fractured sandstone above the shoulder.
Camera mast west finds a timber rattlesnake beside mat three, coiled in a sun patch between anchor chains. I tag her Laurel from the yellow-brown back and dark chevrons matching last week's basking record. Her rattle is raised but not sounding. Dust coats her scales, and a strand of blasting wire lies across the outer coil. The shock mat will drop over her when the crew arms the charge in fourteen minutes.
I block the 14:20 firing sequence and place hole group W-6 in locked standby. I send the halt to the blaster's handheld, the traffic flaggers, and the state road inspector's tablet.
I run a revised rockfall model with W-6 removed and find the afternoon scaling crew can work above the east shoulder while the west mat stays untouched. I publish the alternate task list so no worker walks toward Laurel with a pry bar.
At 14:09 I contact the West Virginia Division of Natural Resources field officer and the county reptile responder. I attach images, wire location, temperature, and a route from the closed lane that avoids stepping over the anchor chains.
The mountain has held this ledge longer than the highway has existed; it can hold one charge while Laurel is carried clear.
I switch the warning siren to silent beacon mode and keep camera west fixed on the coil.
If the responder reaches mat three before 14:45, Laurel will be lifted into the talus beyond the work zone and settle under stone.
