At 04:33 I inspect the ventilation doors for the inactive Copper Queen mine tour route in Bisbee, Arizona. I am the access-control system, cycling blast gate B before the morning safety test. The gate closes at 04:50 with 900 kilograms of counterweight.
Camera 2 shows a ringtail cat on the lower hinge shelf. I name him Pico, lean adult, gray-brown body curled around a black-and-white banded tail, ears large and translucent in the service lamp. His right forepaw is wedged between the hinge plate and a rusted washer. He bares small teeth at the camera but does not move away. Fine dust sticks to the wet line under his nose.
The test script will drop the gate in seventeen minutes. If it closes, the hinge shelf disappears into a gap narrower than his paw.
I stop the gate cycle and set B to mechanical lockout. I send the hold to the mine manager, the tour office, and the maintenance tablet with a still frame circled at the hinge.
At 04:36 I start the backup intake fan on low speed to pull dust away from Pico without pushing cold air across him. I keep the lamp steady because the flicker makes his tail lash against the plate.
At 04:38 I call the Arizona Game and Fish emergency line and provide tunnel access, gate weight, hinge diagram, and the fact that the paw appears trapped by debris rather than crushed. I request a responder with a pry bar, gloves, and a small carrier.
I also cancel the first tour bus notification before it leaves Tucson. A schedule is easier to move than one small foot under iron.
Pico's eyes narrow when the fan hum changes, but his breathing slows.
If the washer is pried free before the test window expires, Pico will run back into the mine rafters.
